  • Immunohistochemical expression of proliferation markers in canine

    • Abstract: Canine osteosarcoma is an extremely malignant bone tumor that often arises in the bones of the limbs. It is a highly metastatic disease distinguished by proliferative bone lesions and a tendency for pulmonary metastasis. Overexpression of proliferative proteins are associated with bad prognosis in human osteosarcoma. Here, we tested the expression of the different proliferative proteins (p53, p16, vimentin, and mdm2) in nine archival samples with canine osteosarcoma. Paraffin-embedded tissue sections were confirmed by histopathology and stained by immunohistochemistry for p53, p16, vimentin and mdm2. Positive expression of these proteins was evaluated as the ratio of positive cancer cells and the intensity staining was assessed in several areas. Histopathologically, 95% of samples were grade II and III. All high-grade osteosarcomas were particularly cellular. The cancer cells were generally large spindle-shaped and large nucleus with distribution of osteoid between the cancer cells. Immunohistochemical detection of p53, p16, vimentin and mdm2 was 89%, 56%, 78%, and 89% of samples respectively. The staining intensity for p53, p16, vimentin and mdm2 was particularly nuclear in 81%, 66%, 78%, and 79% of the cancer cells respectively. Our present work suggests that p53, p16, vimentin, and mdm2 were detected in grade III canine osteosarcomas samples. In addition, these proliferative markers are the significant biomarkers in canine osteosarcomas and can be used as a predictor for diagnostic and prognostic value and allowing cancer differentiation. This primary data supports that both canine and human osteosarcomas share same molecular characters which are approved by expression of proliferative genes.

  • Use of black soldier fly (Hermetia illucens) prepupae amino acids as anti
           Aeromonas hydrophila ...

    • Abstract: Aeromonas hydrophila is an opportunistic freshwater. These bacteria cause gastroenteritis and septicemia in animals and humans. Hemolysin and aerolysin, are important in the pathogenesis of A. hydrophila. Prepupae Black soldier fly (BSF) can be used as an antibacterial using its active substance against hemolysin and aerolysin. This study aimed to determine how the interaction of prepupae BSF amino acids with A. hydrophila enterotoxin in silico and protein level in various substrates in vivo. The study consisted of BSF larva of T1 (fed fruit waste), T2 (fed fermented fruit waste), T3 ((fed tofu waste), T4 (fed fermented tofu waste), and T5 (fed fermented fruit waste and tofu waste). Data on the difference of protein level of prepupae among groups were analyzed statistically using the ANOVA test. The study showed that the highest protein content of BSF prepupae was found in treatment T3 dan T4. Protein docking analysis showed that L-arginine had the most hydrogen interaction (11 H-bonds) with aerolysin and 10 H-bonds against hemolysin, indicating an antibacterial role. The most favorable interacting residues of 17 amino acids against hemolysin were ARG73, ASP74, THR541, ALA523, and ASN483, while the residues of the active site against aerolysin were ASP92, ARG394, SER354, TYR348, ARG356, VAL396, PRO395, and ASP350. Amino could inhibit the hemolytic toxin of Aeromonas by interacting with binding site residues. The better the nutritional value of the substrate given to BSF larvae, the higher the protein content of BSF prepupae. Proteins from BSF prepupae can be antibacterial candidates against A. hydrophila.

  • Microscopic and PCR-based detection of Babesia bovis and Babesia bigemina
           in camel females from ...

    • Abstract: This study was carried out to identify the etiological pathogens responsible of protozoal-like disease conditions occurred in camel females from Al-Diwaniyah Province, Iraq. For this reason, 125 camel females (one blood sample per animal) that showed signs of weakness and pale mucus membranes were considered for the study. The samples of blood were explored microscopically and via the use of a polymerase chain reaction (PCR) method that the targeted glutamine-dependent carbamoyl phosphate synthase (CPSII) gene for identifying Babesia bovis and 18S rRNA gene for detecting B. bigemina. The results of the microscopic technique uncovered the occurrence of babesia spp. in 76 (60.8%) of the examined samples, which encourage the use of the PCR to identify the protozoal species. The PCR findings demonstrated that B. bovis and B. bigemina were detected in 8 (8.9%) and 11 (12.22%), respectively, of the positive microscopic samples. The study findings reveal that weakness and paleness of mucus membranes in camel females can be attributed to the presence of infections by blood protozoa, mainly Babesia bovis and Babesia bigemina.

    • Abstract: The present study was designed to investigate the protective and curative potentials of Moringa oleifera (MO) leaves powder against streptozotocin (STZ) induced type 1 diabetes mellitus (T1DM) in rats. Fifty adult Wistar male albino rats were randomized divided into five equal groups: The normal control group, the Moringa group, The diabetic group, the therapeutic group, the diabetic rats (3 days after STZ injection) were received MO for successive 8 weeks and the prophylactic group, the rats were received MO for 2 weeks before STZ induced diabetic rats and lasted for 8 weeks. The protective or treated oral administration of 1 ml freshly prepared aqueous leaf decoction of MO revealed a significant upregulation on the mRNA expression of PDX-1, Ngn3, VEGF, IGF-1 and GLUT-2. Additionally, it induced a significant downregulation of FBG level in comparison with that of the diabetic group as well as a significant reduction in the level of MDA and a significant elevation in the TAC level. Furthermore, the histopathological observations of pancreas, liver and kidneys tissues affirmed the improvement in treated and prophylactic groups in comparison with STZ-diabetic groups and the improvement in prophylactic group was most distinct than treated group.MO aqueous leaf extract can treat and protect against STZ-induced T1DM, via its antioxidant action (increase the TAC and decrease MDA). Thus, it has the potential for utilization as a prophylactic against diabetes.

           Haemonchus contortus ...

    • Abstract: This study investigated the benzimidazole resistance in Haemonchus contortus parasitic nematodes from sheep from October 2021 to December 2022 in AL-Diwanyiah city/Iraq and samples were processed at the laboratory of Parasitology in Veterinary Medicine College of Al-Qadissyiah University through the detection of E198A mutation and SNP polymorphism of the β-tubulin gene at this codon position. A total of 90 adult H. contortus samples collected from abomasum of sheep (n = 400) and then tested by qPCR and tetra-primer ARMS-PCR. Of these, three different genotypes have been found for E198A SNP: heterozygous (RS), homozygous (SS), and homozygous resistant genotype (RR). The frequencies for these genotypes were 31.11% heterozygous, 57.77% homozygous, and 11.11% homozygous resistant. The current study indicated for the first time the spread of benzimidazole resistance for H. contortus of sheep in Iraq / AL-Diwnayiah by utilizing qPCR and tetra-primer ARMS-PCR. It is speculated that the BZ-resistance is due to excessive and irregular H. contortus drug abuse and inter-species transfer between ruminants at the commonly grazing pastures and from imported sheep as well.

  • Molecular Evidence of Schmallenberg Virus Associated by Ovine Abortion
           with Fetal Anomalies in ...

    • Abstract: In late of 2011, Schmallenberg virus (SBV) was observed in Germany using genomic analysis. The virus is transmitted through haematophagus insect vectors and vertically from females to their offspring across the placenta. In adult sheep, the virus causes a short viremia followed by lethargy, abortion, and dystocia when giving birth to malformed lambs. RT-PCR for virus detection and commercial ELISAs for antibody detection were rapidly developed. There have been no previous studies to detect SBV in sheep in Nineveh province. Thus, this study was therefore intended to investigate the presence of SBV in ovine aborted fetuses and to describe the macroscopic lesions that associated with it. Fifteen aborted lambs, aged between 70 to 135 days, between October 2021 and January 2022 were collected. Brain stem, spinal cord, spleen, liver, lung, and abdominal fluid were collected and stored at -20ᵒC for molecular analysis. Viral RNA was extracted from these collected samples and reverse transcription was performed in one step. RT-PCR was applied to amplify the SBV gene (S segment). Three of fifteen lambs showed marked malformations in vertebral column, arthrogryposis, hydranencephaly, cerebral and cerebellar hypoplasia and porencephaly. SBV was detected in malformed aborted lambs by RT-PCR with 474bp product size. These findings indicate that SBV causing abortion with malformations. Further studies on this topic should be conducted and include isolation and characterization of virus and SBV epidemiology.

  • Acute toxicity events of ivermectin in chicks model

    • Abstract: Ivermectin is a very safe drug however; there are many studies on its toxic effects in different types of animals due to sensitivity, misuse or accidental overdose. The aim of this study was to further characterize the neurotoxic effects of ivermectin in chicks and to identify possible therapeutic strategies for use in cases of ivermectin toxicity. The LD₅₀ of ivermectin was determined by Dixon method. The acute toxicity signs of ivermectin were induced at doses 131.5,2629,and 394.5 mg/kg orally. The therapeutic effect of flumazenil on ivermectin poisoning was also studied. Administration of repeated doses of ivermectin for five consecutive days was recorded to measure the neurobehavioral within the open field and tonic immobility test. The oral LD₅₀ of ivermectin was 525.9mg/kg. The acute signs of poisoning that appeared on ivermectin-treated chicks were lethargy, ataxia, tremor, diarrhea, recumbency, and then death. Flumazenil at dose 0.1mg/kg significantly reduced the toxicity signs induced by the ivermectin in chicks, especially tremor and ataxia, and also prevent the incidence of death. The administration of ivermectin at 26.3, 52.6, and 105.2mg/kg doses led to a significant decrease in motor activity through a significant increase in the time of starting the movement and a decrease in the number of cross lines. We concluded that ivermectin, has a neurotoxic effect in chicks when used in high doses; the results also indicate a potential clinical application of flumazenil for treatment side effects and toxicity of ivermectin, as well as ivermectin has depressant effect in chicks represented by open-field activity

    • Abstract: The vaccination process and immunological status of chickens during their life period have great importance in the poultry industry. We aimed in the current study to evaluate the effect of ProbChick® on the immunological status of broiler chickens after vaccination with Newcastle vaccination using the LaSota strain. A total of 200 one-day-old chicks were divided randomly into five groups. The first group is considered a control group. The second group consumes ProbChick® with drinking water. The third group was vaccinated with the Newcastle vaccine (LaSota strain). The fourth group was vaccinated with the Newcastle vaccine the after 7 days the ProbChick® was consumed. The fifth group was vaccinated with the Newcastle vaccine and consumed ProbChick® on the same day. The result showed that ProbChick® enhances the weight gain, food conversion ratio, and relative weight of bursa of Fabricius and spleen, in addition to that ProbChick® will enhance the antibody titer if it's added to drinking water on the same day of vaccination and give good antibody titer in compare to control groups and in comparison to a group where it is added to drinking water after 7 days of vaccination. We conclude that adding ProbChick® to the broiler at 1 g/litter of drinking water at the same of vaccination by Newcastle vaccine using the LaSota strain will enhance the immune response during vaccination and after vaccination, this will improve the efficiency and titer of antibody production.

    • Abstract: To determine the level of food safety and sanitation practices and make comparisons between very small halal and non-halal beef slaughterhouses in the United States, we conducted two web-based surveys by using a similar questionnaire and similar data collection methods. Among the 80 halal slaughterhouses included in this study, 56.25% (45 out of 80) participated, while 63.75% (51 out of 80) participated in the non-halal slaughterhouse survey. The results of this study showed that there were no significant differences between halal and non-halal slaughterhouses in term of food safety and sanitation practices and food safety technologies and microbiological testing practices. All halal and non-halal slaughterhouses conducted generic E. coli (100%) for beef carcasses. The most common interventions used in halal slaughterhouses were a combination of treatments (cold water + hot water (180 °F) + organic acid) (31.1%). Whereas the most common interventions used in non-halal slaughterhouses were hot water (180 °F) only (33.5%). The findings of this study can be used to describe food safety and sanitation practices in the halal meat industries and find areas for the improvement.

    • Abstract: To date, information related the skeletal morphology of fish in Indonesia is still limited. Therefore, we firstly described the morphology of the cranium of African catfish (Clarias gariepinus) collected from aquaculture pond in Aceh Province, Indonesia. In the present study, research methodology included the preparation of cranium, photographing, editing images and identifying the terminology of cranium. The cranium was prepared physically and chemically. Each part of the cranium was documented using a Canon EOS 700D camera and edited using Adobe Photoshop CS6. The cranium nomenclature was determined by comparing the similarity of the shape and location of each part of the fish cranium that has been studied previously. The cranium of African catfish was divided into two major parts, namely neurocranium (ossa neurocranii) and splanchnocranium (ossa splanchnocranii). Neurocranium had four regions belonging to etmoidal, orbital, otic and occipital, while splanchnocranium had five regions belonging to maxillaris, mandibularis, arcus mandibularis, arcus hyoideus, and apparatus operculare. The African catfish had a strong and thick neurocranium structure. However, orbital, arcus hyoideus and apparatus operculare regions were not well developed. The results of this study could be used as a basic for further research, especially in the field of taxonomy and phylogeny of fish.

    • Abstract: Abstract The study was designed to determine the role of adding hyaluronic acid as a supportive filling material to improve grafting process of experimentally defective tibial bone in dog model. Eighteen local breed dogs of both sexes weighted 18± 0.4 kg and aged (12± 0.6Months) were randomly allocated in two equal groups. In the first group, twelve dogs underwent experimental tibial bone defect (2.5×0.7 cm ) and replaced with deprotenized lamb ribs. The second group were treated as that for the first, but supported by adding 1% hyaluronic acid, to their grafts. The bone in both groups was firmly fixed by cerclage wire. All dogs were; followed-up clinically, radiologically and macroscopically at (14, 30 and 60 days after the intervention. In all study dogs the systemic infections, signs of seromas, hematoma and sever lameness were not developed along the period of the study . Grossly, dogs in the second group at 60 days showed an increase in the size of the filler of bone at the edges and in the mid of the defect, improvement and acceleration in the bone healing, and formation of bone bridges compared to the first group. Radiological finding exhibited complete healing of the fixated bone segment with the surrounding area; however, some cortical irregularities denoted chronic periosteal reaction and callus formation in the treatment with hyaluronic acid. In conclusion, the study indicated that hyaluronic acid with xenograft materials exhibited remarkable beneficial effects on improvement of the tibial bone defect augmentation

  • The effects of thyroidectomy on healing fracture in rabbits model

    • Abstract: This research aims to investigate the fracture healing effects caused by thyroidectomy. The experiment involved sixteen matured male rabbits of local breed which divided into 2 equal groups (control and treated). Rabbits anesthetized by premedicated atropine sulphate, then 15 minutes later, a mixture of Xylazine Ketamine was used. The control group rabbits were induced with mid-shafted femoral fracture, with that, the fixation by intramedullary pinning was considered Meanwhile, the treated group rabbits were induced with same method mentioned above, but fracture were fixed after thyroidectomy and measurement of thyroxin a week after thyroidectomy. Results which were obtained from the clinic revealed signs of severe inflammatory reaction in control group which were higher comparing to treated group. These sings were disappeared within 4-5 days in treated group, while, it took 5-6 days in control animals. Also, radiological results of 2 groups showed that a periosteal reaction was observed towards the end of the 2nd week in the control group, whereas, the treated group showed its reaction at the end of fourth week, there was an invisible fracture line for both control and treated groups at the end of fourth and seventh week, respectively. In addition, bony bridge in the control groups became remodeled into a lamellar bone earlier than treated group. The results of measuring thyroxin hormone before and after the thyroidectomy confirmed the essential role of this hormone in fracture healing. To conclude that the fracture healing maturity was greater in control group than in treated group.

  • Renal ameliorating effect of resveratrol in hydrogen peroxide induced male

    • Abstract: The study aimed to investigate the potential effect of resveratrol (RS) supplementation in attenuating kidney injury induced by hydrogen peroxide (H2O2) in male rats. Forty adult male rats were randomly assigned into four groups (10 each). The control group was orally supplemented with distilled water, and group G1 was orally supplemented with tap water containing 0.5% of H2O2, G2: was orally supplemented with tap water containing 0.5% of H2O2 and RS 87 mg/kg BW, and G3 was orally supplemented with RS 87 mg/kg BW. Blood samples were obtained before treatment and after 45 days of daily treatment. Serum concentrations of creatinine (Cr), urea nitrogen (UN), and total bilirubin were assessed. On day 45, male rats were euthanized, and kidney samples were taken to estimate malondialdehyde (MDA) and superoxide dismutase (SOD) concentrations, and other samples were obtained for histopathological examination. The results showed a significant increase in creatinine and BUN concentrations accompanied by a significant increase in MDA and a decrease in SOD in kidney tissue in G1 group male rats compared to other groups. Resveratrol partially restored the studied criteria related to renal functions by modulating the histopathological changes in the kidney induced by hydrogen peroxide. It could be concluded that supplementation of resveratrol to oxidatively stressed rats maintains the antioxidant defenses mechanism and could be helpful in the prevention of renal oxidative stress.

    • Abstract: Many studies are still the subject of food additives to know their positive and negative effects, primarily as they are widely used globally. Therefore, this study aimed to identify the histological effects of sodium nitrite and monosodium glutamate on the histological structure of the kidney in pregnant rats. Twenty-four pregnant rats were used to achieve the aim of the study. The rats were classified into four groups, the first being the control group, the second treated with monosodium glutamate at 10 g/kg, the third injected with sodium nitrite at 115 mg/kg, and the fourth for interaction between the two substances and for the same concentrations. The results showed the occurrence of many lesions in the kidneys of experimental groups rats. The second group included interstitial tissue hyperplasia and necrosis of the glomeruli, infiltration of inflammatory cells, congestion of blood vessels, hydropic degeneration of some tubules, and necrosis of some of them. The third group included congestion, hemorrhage in the pulp area, degeneration of some urinary tubules, necrosis, and deformation of the glomerulus. However, degeneration of some tubules and necrosis were seen in the fourth group, such as glomerulus hyperplasia, reduction of Bowman's space, an increase in acidity of the cytoplasm of epithelial cells tubules, hyperplasia of the fibroblasts, and the desquamation of some tubules. The study concluded that these substances have harmful effects on the kidneys in pregnant rats, especially when they are overlapped, so they must be avoided during pregnancy to maintain kidney health.

    • Abstract: Thepresent study was carried out to describe some epidemiological facts of myiasis infestations in cattle; therefore, Staphylococcus aureus was isolated and identified from various infested sites with maggots from February to September 2019. It involved three districts (Shatt-Alarab, Al-Qurnah, and Al-Dyr) north of Basrah Governorate/Iraq. A total of 54 herds/owners were visited, with 150 cattle were found to be infested with maggots and diagnosed from different sites of the animal body. The result was indicated that 31% (95%Cl, 26.9-35.4) of examined animals were infested with myiasis, and there were no significant differences detected between sex and ages of the animal groups under study. Staphylococcus aureus was diagnosed using classical methods as morphological characteristics, physiological (coagulase tube method), biochemical tests, and growth on selective medium as Mannitol Salt Agar (MSA) at a percentage of 32% (48/150). Polymerase chain reaction (PCR) was performed to amplify the nuc gene in this isolated species, indicating the presence of nuc size (423) bp compared with a ladder used. The study clearly states that myiasis is a severe threat to cattle populations and that veterinary and agriculture authorities must recall control measures. These measures should be forged to include using a trapping/catch system, applying effective treatment, spraying pesticides, and sterilizing male flies with radiation to inhibit producing offspring.

    • Abstract: Abortion is one of the most critical factors affecting lambing rates and, as a result, sheep farm profitability. It is also significant from a zoonotic viewpoint, in addition to financial losses. In sheep flocks, Campylobacter fetus causes infectious infertility, embryonic death, and miscarriages. The study investigated C. fetus from aborted fetuses and vaginal swab samples collected from sheep flocks in the Sulaimani province by the polymerase chain reaction. Thirty-eight aborted fetuses and 70 vaginal swabs were collected from sheep flocks in three districts of Sulaimani province (Kalar, Said Sadiq, and Chamchamal) from March 2018 to June 2019. The pathogen was identified in clinical specimens using conventional PCR. C. fetus was isolated in 16 of 38 aborted fetuses (42.1%) and 13 of 70 vaginal swabs from aborted ewes (18.6 %). The C. fetus gene 16S rRNAwas sequenced and received the accession number MW694741 in NCBI GenBank. Phylogenetic analysis of 16S rRNA gene sequences designated that the C. fetus isolates formed a separate branch displayed the highest similarity and clustered with MN203686.1 and EU773268.1 accessions in a specific clade. A lower degree of affinity of C. fetus was revealed with Campylobacter coli and Campylobacter jejuni.

    • Abstract: The current work emphasized understanding the liver functions while having pre-clinical or clinical fascioliasis accurately detect the disease phase from cows in Al-Diwaniyah City, Al-Qadisiyah Province, Iraq. The experimental design included the use of 30 cows in Al-Diwaniayh province divided into ten clinically healthy cows (control group), ten acutely infected cows with no apparent clinical signs (pre-clinical group), and ten chronically infected cows with observed clinical signs (clinical group), such as yellowish discoloration of the mucus membranes. Blood samples were collected from each cow for performing the following tests: Alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST), gamma-glutamyl transferase (GGT), serum levels of pyruvate, lactate, and Cholesterol. The results showed that all the enzymes from the pre-clinical group were significantly (P<0.05) higher in their serum levels compared with those from the control group to elevate to significantly (P<0.05) higher levels in the clinical group in comparisons with those from the control and pre-clinical groups, excluding the ALT that revealed no significant (P>0.05) difference between the pre-and clinical groups. A significant (P<0.05) increase was seen in the pre-clinical group compared to those from the control group, with no significant (P>0.05) difference between the pre-and clinical groups. No significant (P>0.05) differences were recorded between all study groups at serum pyruvate and lactate levels. The present study reveals that the fascioliasis, dependent on the infestation phase, can progressively change the serum levels of the parameters mentioned above and may feasibly be used together as indicators for the accurate detection of the disease stage.

This study aims to monitor the prevalence of biofilm-forming Aeromonas species in the drinking water distribution systems in different broiler chicken farms. The antimicrobial activity of thyme essential oil (TEO), thyme essential oil nano-emulsion (TEO-N), chitosan (CS), chitosan nanoparticles (CS-NPs), and both CS and CS-NP-based coating TEO against the different Aeromonas spp.was evaluated using the broth microdilution and agar well diffusion assay. The overall prevalence rate of Aeromonas spp. was 49.3% (74.0/150). The highest rate of Aeromonas isolates was noted in water drinkers and tanks 75.0% (30/40) and 62.5% (25/40), respectively) followed by feedstuff 40.0% (12/30). In contrast, the highest percentage of biofilm-producing Aeromonas spp. was Aeromonas hydrophila 70.0% (14/20) followed by Aeromonas caviae 30.0% (6/20). The fatal effect of CS-NPs against all isolated Aeromonas spp. was achieved 100% at 1.5 and 2.0 µg/mL. Moreover, chitosan nanoparticles coating thyme essential oil (CS-NPs/TEO) verified the lethal effect 100% on both A. hydrophila and A. caviae at the ratio of 1:1 and 1:0.75 µg/mL. In conclusion, the main source of Aeromonas spp. in the drinking water distribution system was the unhygienic status of water tanks and drinkers that allowed biofilm to produce due to aggregation of Aeromonas bacteria on the inner surface of that equipment. Both CS-NPs and CS-NPs/TEO could be applied as a sanitizer and/or disinfectant for Aeromonas biofilm control.

  • Evaluation of histological changes induced by prednisolone and
           cyclophosphamide in some organs ...

    • Abstract: Prednisolone is a synthetic corticosteroid used to treat various diseases. It is known to be used to treat many conditions such as autoimmune diseases and asthma. Cyclophosphamide is a type of nitrogen mustard therapy that works by alkylation of DNA and is used as an immunosuppressant in rheumatoid arthritis and the treatment of many cancers as well. Due to the wide use of these two drugs, the study aimed to evaluate the histological changes in the liver, kidneys, and small intestine of mice. Seventy-five adult mice aged 8-12 weeks were used which were divided into three groups, the first group was orally dosed with 0.1 mg/kg prednisolone, the second group was orally dosed with 0.1 mg/kg cyclophosphamide, and the third group received orally distilled water for 30 days daily. After 24 hours of the last treatment, the animals were sacrificed and the organs (liver, kidney, small intestine) were taken out and placed in 10% formalin solution until histological techniques were performed. The results of the study showed a statically significant difference at P>0.05 of histological changes in the studied organs represented by necrosis, fibrosis, cell degeneration, congestion, and hemorrhage of blood vessels and inflammatory cells when compared with the control group, and that the highest significant difference for these changes was at grade 1 and 2. Our study confirms that these drugs cause histological changes that differed in severity between organs as well as within a single organ when compared to the control group and that cyclophosphamide causes more histological changes than prednisolone.

  • Abortion in ewes in Nineveh governorate, Iraq: A systematic review and

    • Abstract: The current study was designed to examine the evidence and knowledge gaps in studies investigating abortion in ewes in Nineveh, Iraq, and quantify the overall incidence of abortion and the prevalence of potential infectious etiology of abortion. PubMed, CABI, and GoogleScholar databases were used as search engines to track pertinent peer-reviewed studies. Additional relevant articles were identified by reviewing the reference lists of identified full-text articles and contacting colleagues who worked on pertinent topics. Identified studies were divided into two main groups, including studies that reported the abortion rate in ewes and studies that reported the potential infectious etiology of abortion. A meta-analysis was performed for each group.A total of 17 studies were qualified for review, including six studies that reported the abortion rate. All of the 17 studies examined the prevalence of potential etiology of abortion. The overall incidence of abortion was 7.32%, and the pooled prevalence of potential infectious etiology of abortion indicated that 51.43%, 31.92%, and 6.83% were for Toxoplasma gondii, Brucella spp., and other pathogens, respectively. In conclusion, it is essential to identify epicenters of abortion in Nineveh, the association between the incidence of abortion and parity, the effect of pregnancy season on the incidence of abortion, and confirm the prevalence of T. gondii in aborted ewes is high.

  • Study the role of KSper current for controlling the Ca2+ influx and
           intracellular pHi in mouse ...

    • Abstract: This work was aimed to explore the details of the ion channels gating and there physiological role in sperm in the future.Mouse spermatozoa express a pH-dependent K+ current (KSper) thought to induce hyperpolarization to enhance Ca2+ influx via alkaline-activated calcium channel (Catsper) to initial a so-called sperm capacitation by NH4Cl during travelling in female genital tract for fertilization. However, the regulating mechanism of the Ksper and Catsper channels by membrane potential and pHi remains uncertain, because the complexities of two channel kinetics in sperms is hardly to be overcame at this stage. Here we show that difference of the intracellular [Ca2+]i between the wild type (Wt) and knockout (KO) Ksper (or Slo3/) mice in the application of the Slo3 blockers, Guinidine (QD) and Clofilium, and NH4Cl, indicating that Ksper channels, encoding Slo3 gene, dominates the membrane potential of mouse sperms to increase the intracellular [Ca2+]i and [pH]i during the capacitation process to play a vital role in fertility. Furthermore, a HH model sperm built directly with the native Ksper and Catsper currents in sperms reveals two functions of membrane potential and intracellular pHi, allowing us to calculate the intracellular pHi by NH4Cl, based on membrane potentials recording from current-clamp experiments. During modeling, we found a caton channel with Vrev= +20 mV in mouse sperm from the double-KO (i.e. Catsper-/- and Ksper-/-) mice, which is definitely necessary for a model able to match the data.

           drugs on sciatic ...

    • Abstract: The ongoing work aims to compare the effect of extraneural and intraneural injection of therapeutic doses of meloxicam and diclofenac sodium on the sciatic nerve of rats. Six groups of adult albino rats were used with five animals per group. Control group (A), group (B), and group (C) received a single extraneural injection of normal saline (NS) 0.25 ml/kg/rat, meloxicam (M) 0.11 mg/kg/0.25ml/rat and diclofenac sodium (V) 1.1 mg/kg/0.25ml/rat respectively. In contrast, control group (D), group (E), and group (F) received a single intraneural injection of the same doses of normal saline, meloxicam, and diclofenac sodium, respectively. Histological evaluation reveals an increased thickening of epineurium, dilatation, congestion of epineurial blood vessels, intrafascicular edema, axonal degeneration, myelin degeneration, and vacuolization in group (C) which was higher than those in the group (B). These changes were also greater in group (F) compared to groups (D) and (E). The histopathological changes of the sciatic nerve were greatest in the case of intraneural injection of saline, meloxicam, and diclofenac sodium, which means that the damaging effect of intraneural injection of the drug was greater than the extraneural injection of the same drug. It is concluded that extraneural and intraneural injections of therapeutic doses of meloxicam cause less damage to the sciatic nerve compared to diclofenac sodium. Thus it is considered to be more secure than diclofenac sodium after intramuscular injection. Sciatic nerve injury can occur following intramuscular injection into the gluteal region, particularly if the needle hits the nerve.

  • Prevalence of avian influenza in humans and different bird species in
           Indonesia: A review

    • Abstract: Avian influenza, commonly called bird flu, is highly contagious and pandemic zoonosis of global importance, primarily affecting birds and other mammals, including humans. The present review is intended to highlight a report on the prevalence of avian influenza in humans and different bird species of Indonesia.The study is based on 27 scientific articles from 2004 to May 2021 in which the prevalence of avian influenza is determined mainly by the following molecular, virological, and serological tests: polymerase chain reaction (PCR), hemagglutination inhibition (HI), enzyme-linked immunosorbent assay (ELISA), and ®Rapid antigen detection test. A vast divergence in the prevalence of avian influenza was observed due to the diversity in sensitivity and specificity of the tests applied. The prevalence of avian influenza varies due to spatial and temporal factors, bird species, and breed differences. An average maximum prevalence (25%)) was found in poultry (domestic and commercial birds) as compared to ducks (20.13%) and other birds (10.66%). An average documented prevalence (16.3%) was found in humans. Birds sold in live bird markets showed maximum prevalence due to different geographical distribution. The already published studies dissection illustrates that avian influenza infects all types of birds and humans in Indonesia. A proper surveillance system, effective vaccination plan, and segregation and culling strategy regarding avian influenza-infected birds are desperately needed to eradicate avian influenza in Indonesia.

           esophagus between ring-necked ...

    • Abstract: The present study aimed to investigate the esophagus's anatomical, histometrical, histochemical aspects in the Ring-necked parakeet and Black-shouldered Kite. The esophagus in the parakeet was shorter and narrower than the kite esophagus. The crop was a well‐developed sac shape in the parakeet, while the crop was hardly recognizable in the kite. Histological study shows that the esophagus in both species was composed of four layers arranged from inner to outer (mucosa, submucosa, musculosa, finally serosa). These layers showed variances in the height of the fold, the glands number, and the wall layers’ thickness. The mucosa in the esophagus of the kite consisted of non-keratinized stratified squamous epithelium, while in the parakeet, mucosa consisted of keratinized stratified squamous epithelium. The esophageal glands were compound tubuloalveolar in the parakeet, while in the kite, there were simple alveolar glands. The folds in the kite were longest and contained more esophageal glands, while the parakeet glands were more prominent and had fewer numbers within the submucosa. The submucosa layer in the parakeet was thicker than that of the kite. The histochemical results showed a positive reaction of esophageal glands with Alcian blue (PH 2.5), while reacting negatively with Periodic Acid Schiff (PAS) stains due to the acidic mucopolysaccharides secretions nature.

  • Gonadotropin profile in experimentally induced hypothyroid and
           hyperthyroid cyclic female rats

    • Abstract: The current study examined the association of thyroid disorders with reproductive dysfunction by determining its effect on gonadotropin secretion in cyclic female rats. Sixty cyclic females were assigned to three groups (20 each) and supplemented, for 30 days plus two consequent estrous cycles, with drinking water (control), methimazole in drinking water (0.02% w/v) (hypothyroid group), and thyroxine in drinking water (0.002% w/v) and gastric gavage of 200 μg/kg body weight (hyperthyroid group). At late proestrus, ten females from each group (for each cycle) were anesthetized and dissected. Blood samples were obtained to assess thyroid-stimulating hormone, free and total triiodothyronine, free and total thyroxin, follicle-stimulating hormone, luteinizing hormone, and prolactin concentrations. Ovarian and pituitary tissue samples were obtained for molecular analysis of ovarian thyroid receptor genes and pituitary TSH, FSHβ, and LHβ genes. In comparison with control, the Hypo group revealed increased serum concentrations of TSH and PRL and the expression levels of pituitary TSH and ovarian TRsTRs genes and significant decrease of FT3, TT3, FT4, TT4, FSH, and LHLH concentrations and the expression levels of pituitary FSHβ and LHβ genes. In contrast, the Hyper group showed increased serum FT3, TT3, FT4, TT4, and LHLH concentrations and the expression levels of pituitary LHβ and ovarian TRsTRs genes and decreased serum TSH FSH and PRL concentrations and pituitary FSHβ and TSH gene expression levels. It is concluded that thyroid dysfunction is associated with altered serum gonadotropin secretion and reproductive failure.

    • Abstract: This study investigated the effect of resveratrol supplementation on parasitemia, oxidative stress and serum biochemical changes in the Trypanosoma brucei infected dogs. The mean pre-patent period (MPP) of infection was 5.75±0.96 (5-7) days and 9.00 ± 0.82 (8-10) days between infected un-supplemented and supplemented respectively, which differed significantly (p<0.05). There was a significant increase (P<0.05) in the activities of malondialdehyde (MDA) post infection (pi) on the infected untreated group compared with the infected treated groups and the control. The mean serum alanine aminotransaminase (ALT) and aspartate aminotransferase (AST) were significantly (P>0.05) higher than the infected treated groups. The mean ALT of infected treated with both resveratrol and diminazene aceturate (DA) was significantly (P<0.05) lower than other infected treated groups. The mean creatinine and blood urea nitrogen (BUN) levels were significantly (P<0.05) higher in the infected untreated group. The creatinine level of the infected treated with both resveratrol and DA was significantly (P<0.05) lower than other infected treated groups, whereas the BUN did not differ significantly (P>0.05) within the infected treated groups when compared with the control. The mean albumin and total protein were significantly (P<0.05) higher in the infected untreated group, but the infected treated groups did not show any significant (P>0.05) difference. However, the total protein was significantly (P<0.05) higher in the infected treated with resveratrol than in other infected groups. It was concluded that pretreatment with resveratrol is beneficial in managing T. brucei infection, as it delays the onset of parasitemia and restores damages done to the liver and kidneys when combined with diminazene aceturate.

  • Secondary bacterial infection of hydatid cysts infected livestock animals
           (In vitro study)

    • Abstract: Isolation and identificationof the bacteria-infected hydatid cystsof livestock animals were carried out. The study lasted for five months. A total of 302 slaughtered livestock were checked to find hydatid cyst naturally infected livers and lungs of sheep and goat at local Mosul abattoir/ Nineveh/ Iraq. Each cysts' aspirated fluid was cultured separately on blood or nutrient agar at 37C for 24 hours then detected secondary bacteria. Each bacterium was incubated independently with 1000 viable protoscolices in a culture tube containing tryptic soy broth at 37°C and examined every two hours for 6 hours, followed by 12, 24, 36, and 48 hours afterward.The degeneration rate of protoscolices resulting from treatment with bacteria isolated depending on viability was studied in vitro.The results were revealed that the liver was the preponderant affected organ in sheep and goats. About 57.1% of sheep and 50% of goats harbored fertile cysts. Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus, Proteus mirabilis, and Pseudomonas aeruginosa bacteria were observed in the infected cysts. The most common bacteria infect the cyst was Escherichia coli. The protoscoleces treated with the bacterial isolates had completely deteriorated, whereas 97% of protoscoleces throughout the control groups were still alive and intact even after completing the incubation time. The experiments detect a significant time-dependent scolicidal effect on decreased viability of protoscolices in vitro study. This could pave the door for more research into the scolicidal validity of bacteria or their by-products as protoscolices both in vitro and in vivo.

           avian species: A ...

    • Abstract: This study aimed to explain and compare the anatomical, histological, histochemical and histomorphometrical analyses of the trachea in different species of birds. This study includes 21 healthy birds from geese (Anser anser domesticus), cattle egrets (Bublucus ibis) and house sparrows (Passer domesticus), 7 seven from each species. Anatomically, the trachea of the goose (the proximal and distal parts) was the longest of all the studied species, yet it had fewer cartilaginous rings than those of the cattle egret. Also, the tracheal length, beside the tracheal muscle in geese plays an important role in the phonation process. Histologically, the trachea is composed of four distinct tunicae: mucosa, propria submucosa, fibrocartilaginous, and adventitia. The epithelium that lined the trachea was ciliated, pseudostratified columnar epithelium (respiratory epithelium) with simple mucous tubuloalveolar glands in either proximal or distal parts depending on the species. The proximal part is made up of overlapped hyaline cartilaginous rings that partially ossified in geese and cattle egrets but did not ossify in sparrows. In the distal part, the overlapping faded in three investigated species.

  • Transabdominal ultrasonographic determination of pregnancy and fetal
           viability in mares

    • Abstract: The study was designed to evaluate the efficiency of transabdominal ultrasonographic approach for pregnancy diagnosis and monitoring the viability of fetus in mares as an alternative approach to the transrectal ultrasonography to minimize the opportunity of misdiagnosis and prevent the deleterious effect of transrectal invasive. Forty-five mares were scanned by transrectal and transabdominal ultrasonography. Results showed that 26 mares were pregnant and 19 mares were non-pregnant. The accuracy, sensitivity, specificity, the positive and negative predictive values of both approaches were 100%. Transabdominal approach required less time in comparison to transrectal ultrasonography to reach the final decision for non-pregnant mares 5.26±0.27 vs. 8.11±0.31 min, mares at second trimester 4.36±0.49 vs. 5.57±0.29 min and third trimester 4.12±0.51 vs. 5.86±0.26 min, respectively. Both methods recorded no significant correlation between the scanning time and the gestational age. The positive predictive values for determining fetal viability were 26.9% for transrectal and 80.8% for transabdominal ultrasonography. A significant variance was reported between the positive predictive values obtained by transrectal and transabdominal ultrasonography. In conclusion, the transabdominal is an effective, practical, and often essential approach of ultrasonographic for determination of pregnancy and fetal viability in mares, especially at the second and third trimesters of pregnancy. We recommended transabdominal ultrasonographic scanner as the first examination for mares presented for pregnancy diagnosis, if this approach does not accurately diagnose, the mares can be scanned transrectaly. So, we can minimize the stress and hazard of the transrectal examination.

  • Antidiabetic of Hylocereus polyrhizus peel ethanolic extract on alloxan
           induced diabetic mice

    • Abstract: Diabetes is a disease characterized by high blood glucose due to the abnormal response of the cells in the body on produced insulin or insulin resistance. Indeed, the treatment for diabetes mellitus lasts for a lifetime and causes various side effects, such as headache, hypoglycemia, vomiting, and gastrointestinal symptoms. Interestingly, Dragon fruit has potent antidiabetic activity and without side effects. Thirty Wistar mice were included in the study. Alloxan with a dose of 150 mg/kg was injected intraperitoneally to all groups except the standard control group. Mice with blood glucose levels higher than 200 mg/dL were considered diabetic and employed throughout the study. Mice were divided into five groups: standard control group without alloxan, diabetic control group with alloxan, treatment group of 100 mg/kg and 300mg/kg H. polyrhizus peel extract, and positive control group with 600 µg/kg glibenclamide. All treatments were given orally. Blood glucose level was checked on day 1, 7, and 14 on all groups using Accu-check instant glucometer. This study revealed that administration of alloxan to the diabetic control group significantly increased blood glucose level compared to the normal control group on day-1, 7, and 14 (P < 0.05). In addition, administration of H. polyrhizus peel extract and glibenclamide effectively decreases blood glucose levels, especially on day-7 and 14 compared to the control group (P<0.05).

  • Assessment of the analgesic effect of Alpha-lipoic acid by three acute
           pain models

    • Abstract: Alpha-lipoic acids are Known as a good analgesic in neuropathic pain, especially in diabetic patients. This research aimed to assess the analgesic activity of ALA by three acute pain models using broiler chicks. We used electrical stimulation, hot water test, and formalin test to elicit acute pain. The up and down method was used to calculate the median effect of the analgesic dose. The ED50 of ALA was 45.18 and 74.56 mg/kg intraperitoneally by electrical stimulation and hot water test, respectively. We demonstrated that the peak of analgesic effect was after one hour by using different doses and different times. ALA at 0, 75, 150, 300 mg/kg intraperitoneally produces a dose-dependent analgesic effect by formalin test. In conclusion: ALA induced analgesic activity, probably by closing voltage-gated calcium and or voltage-gated sodium channels. These outcomes show that therapeutic doses of ALA can affect pain and may mask or reduce nociception induced by acute pain models.

  • Effect of dietary BHA supplementation on certain physiological values in
           broiler chicken

    • Abstract: Butylated hydroxyl anisole (BHA) is manufactured from a mixture of two isomeric organic compounds, 2-tertiary-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole, and is widely used in poultry feed as a phenolic free radical scavenger. The current search investigated the impact of different doses of BHA on some hematological and hormonal features of broiler. Fifty-four one-day-old birds were utilized in this study randomly divided into three groups, the control group was given a standard ratio, the 2ed group was given a standard diet filled up with BHA at a rate of 2.5 mg/kg feed, and the 3rd group was given a standard ration fill up with BHA at a rate of 5 mg/kg feed by 18 birds/group, each with three replicates (6 birds/ repeated cycle). The study included three age stages (15, 30, and 45) days. The results showed a significant rise in RBC, WBC, lymphocytes, MCH, SOD, and CAT for the two groups of BHA during 30 and 45 days of treatment compared with the control with a significant improvement in the stress index, as well as a significant decrease in MCV during the three periods of treatment. Supplementation with BHA in both doses caused a significant rise in T3 and T4 during 45 days of the study compared with the control group. We deduce from this research that adding BHA to the poultry diets improved physiological and hormonal characteristics due to its ability to scavenge free radicals. It promotes significant health and growth.

  • Detection of the nuc gene in Staphylococcus aureus isolated from swamps
           and ponds in Mosul city ...

    • Abstract: In most developing countries, rainwater is considered a significant water source for drinking, washing, bathing, and cooking. On the other hand, this water is the medium for transporting microorganisms such as bacteria, viruses, parasites, and fungi to humans and animals. Most domestic and wild animals drink this kind of waterborne illness that leads to various types of diseases, which causes enormous economic losses. The current study was aimed to isolate Staphylococcus (S.) aureus from the swamps and ponds in various areas, including (Qawseat, Kukagle, Besan, Al-Arabi, and Al-Shlalat) that surrounding the Mosul city during the rainfall season. One hundred rainwater samples were collected from swamps and ponds in various Mosul city areas. The classical method and polymerase chain reaction (PCR) technique had used to identify S. aureus isolates. The present study showed that the prevalence rate of S. aureus isolated from swamps and ponds was 12% (12/100) based on the classical and PCR methods used. All the positive S. aureus isolates possess the specific-species nuc gene. In addition, the results of the classical methods are similar to the results of the PCR technique. The present study concludes that the water of swamps and ponds is formed by rainwater exposed to contamination by S. aureus, which posed in the ground and is not fit for the drinking of animals and humans.

  • New surgical model to induce irreversible liver fibrosis by surgical
           closure of major duodenal ...

    • Abstract: This study was conducted to induce and evaluate irreversible hepatic fibrosis in dogs by surgical closure of the major duodenal orifice. The study was performed on six healthy local adult dogs. Irreversible hepatic fibrosis was surgically induced in all animals by surgical closure of major duodenal papilla using non-absorbable suture material for 60 days. Induced hepatic fibrosis was evaluated by clinical, ultrasonographical examination, laboratory and histopathological methods. The clinical manifestation of the jaundiced dogs showed reduced food intake, pale-yellowish mucus membrane, inflammatory signs of wound site and severe post-operative pain. Biochemically, there was significant increased values of the aspartate aminotransferase ,  alkaline phosphatase , alanine aminotransferase , indirect bilirubin, direct bilirubin and total bilirubin especially during first two days after surgery followed by a gradual decrease of these values until the end of the but still higher than normal values. Ultrasonographic examinations showed abnormal change in the liver tissue such as increase in both size and wall thickness of the gall bladder and mottled heterogeneous appearance of the liver during the first two weeks following the surgical induction of the hepatic fibrosis and lasted until the end of the study. Histopathological evaluation of liver samples revealed necrosis of hepatocytes and deposition of eosinophilic material, infiltration of inflammatory cells, recent thrombus in the hepatic vein, fatty change. In conclusion, surgical induction of irreversible hepatic fibrosis in dogs was feasible technique by surgical closure of major duodenal papilla and the results were confirmed by the clinical, ultrasonographical, laboratory and histopathological examination.

  • Morphometric and molecular characterization of Moniezia species in sheep
           in Mosul city, Iraq

    • Abstract: The current study examined 100 small intestines collected randomly from sheep slaughtered in the abattoir and butcher’s shops from different Mosul city / Iraq areas of both sexes (55 females, 45 males) and different ages. Moniezia expansa was diagnosed in 9 samples of intestines by studying the morphometric characteristics of these tapeworms, especially the mature segments, in which both the ovaries and vitelline glands appeared in the ring shape on either side of the body segments and the rosette-like shape of the interproglotidial glands. No significant difference was noticed between males and females of sheep in our study, and the infection rate was 10% in sheep less than a year old and older than two years, with no significant difference between the age groups. The results of the molecular analysis by using conventional polymerase chain reaction technique confirmed the diagnosis of these worms, which belong to the genus Moniezia, with a product reaction of 700 base pairs. The sequencing result shows two strains of Moniezia expanza, which isolated from Iraq (Moniezia expansa-Iraqi one and Moniezia expansa-Iraqi 2) were similar to each other had a significant distance to other strains. The study also showed that Moniezia expansa is different from the same species in other countries.
