  Abstract: AbstractToxoplasma gondii is an obligate intracellular parasite, causing toxoplasmosis in almost all warm-blooded animals and humans worldwide. Toxoplasmosis is a zoonotic disease of serious public health concern. Host cell invasion by T. gondii tachyzoites has process involving the sequential secretion of Excreted-Secreted Antigens (ESAs). T. gondi ESAs could be a valuable candidate for the diagnosis of toxoplasmosis. Techniques to more accurately detection of T. gondii recently developed biotechnological methods that are currently being used, conventional and real time Polymerase Chain Reaction (RT-PCR). RT-PCR is more widely used because it is more sensitive and specific. The aims of this study were to optimize the Sybr Green RT-PCR in different region gene based on Excreted-Secreted Antigens (ESAs), tachyzoite surface antigen and bradhyzoite antige, then adapt the conventional PCR program to real-time PCR for detection Toxoplasma gondii. Optimization is necessary to get optimal condition of PCR to get the best results. T. gondii RH strains derived from liquid nitrogen and DNA extracted by DNAzol. The genetic marker used GRA1#1, GRA1#2, GRA7#1, GRA7#2, ROP1, MIC3, SAG1 and BAG1. The results of the optimization of multiple primer genes can adapt and be used optimal in RT-PCR by using the same cycle program simultaneously in one run. Overall, RT-PCR for the detection of T. gondii DNA demonstrated excellent agreement with conventional PCR. RT-PCR with melting curve analysis is rapid and simple that facilitates high throughput analysis to detect T. gondii. The optimal conditions obtained from the optimization results can facilitate further research to detect T. gondii.Keywords: Biotechnology molecular, Detection, excretory-secretory antigen, toxoplasmosis

  Abstract: The reproductive ability of Holstein Friesian (FH) cows greatly affects milk yield because, however, in the lactation period, dairy cows anestrus postpartus, which is the condition where does not appear in estrus postpartus. Anestrus postpartus to uterine involution as a consequence of nutritional deficiencies. Recovery from can be this condition can be conducted by additional feeding. One of the supplementary feeds is urea multinutrient molasses block (UMMB). UMMB consists of fillers and adhesives and cement is the most used in UMMB production as an adhesive. UMMB is an additional feed using cement dairy cows health problems. Therefore, the objective of this research was to determine the effect of cement substitution with tapioca meal as an adhesive on postpartus estrus of FH cows. A total of 9 lactating FH dairy cows were divided into 3 dietary groups. Each treatment had 3 cows as replicates. The dietary treatments consisted of UMMB with 100% cement adhesive (as D0); 50% cement and 50% tapioca (D1); and 0% cement and 100% tapioca meal (D2). The parameters were postpartus estrus, estrus speed, estrus duration, estrus intensity, and estrogen hormone levels. The results revealed that the treatment had a significant effect (P<0.05) on the duration of estrus, while it had no significant effect (P>0.05) neither on postpartus estrus, estrus speed, estrus intensity, or estrogen hormone levels. Therefore, it can be concluded that tapioca meals can be used as a substitute for cement as much as 50% provides as an adhesive in UMMB production for better estrus performance.

Profil Hematologi, Besi, dan Rasio Mieloid:Eritroid Kuda Hiperimun yang
Digunakan dalam Produksi Plasma Antisera
- Authors: Dinar Arifianto
  Pages: 24 - 31
  Abstract: Kuda merupakan salah satu hewan yang penting dalam produksi plasma antisera sebagai bahan baku pembuatan serum. Akhir abad ke-19 kuda berperan krusial dalam pengembangan serum pertama terhadap penyakit difteri manusia. Hingga saat ini kuda masih digunakan untuk memproduksi berbagai serum anti-venom, anti-rabies, anti-tetanus, hingga anti-SARS CoV-2. Proses produksi plasma antisera diawali dengan injeksi imunogen pada kuda yang disebut dengan hiperimunisasi. Antibodi dalam jumlah besar yang terbentuk dikoleksi kemudian dipurifikasi untuk digunakan pada manusia. Hiperimunisasi menimbulkan berbagai efek samping, diantaranya adalah penimbunan fibril amiloid pada berbagai jaringan yang dapat mengganggu fisiologi dan fungsi organ tubuh. Sebanyak 12 ekor kuda digunakan dalam penelitian ini dan dibagi menjadi 4 kelompok. Kuda kontrol (n=3) terdiri atas kuda yang belum pernah mendapatkan perlakuan hiperimunisasi, sedangkan 9 kuda lainnya dikelompokkan berdasarkan lamanya waktu produksi plasma antisera dengan metode hiperimunisasi (masing-masing kelompok berjumlah 3 ekor). Kelompok I terdiri atas kuda dengan masa produksi 2-3 tahun, kelompok II terdiri atas kuda dengan masa produksi 4-5 tahun, dan kelompok III terdiri atas kuda dengan masa produksi 6-7 tahun. Sampel darah, serum, dan aspirasi sumsum tulang dianalisis utuk melihat profil eritrosit, Hb, PCV, trombosit, profil besi (besi serum, UIBC, TIBC, saturasi transferin), rasio mieloid:eritroid (M:E) dan persentase retikulosit. Analisis statistik menunjukkan bahwa terdapat perbedaan yang signifikan pada parameter eritrosit dan rasio M:E (P<0,05), sedangkan Hb, trombosit, dan profil besi tidak ditemukan perbedaan yang signifikan (P>0,05). Hal tersebut menunjukkan bahwa perlakuan hiperimunisasi menyebabkan terjadinya anemia non-regeneratif dengan mekanisme supresi eritropoiesis sumsum tulang tanpa memengaruhi komponen besi.

Development of In-House ELISA using recombinant LipL32 for Detection of
Human Leptospirosis in Indonesia
- Authors: Sumarningsih Sumarningsih
  Pages: 32 - 36
  Abstract: Early laboratory confirmation is important for the accurate diagnosis and treatment of patient infected by leptospirosis. However, Microscopic agglutination test (MAT) as the gold standard for detection of human leptospirosis has many limitation and only available in reference laboratories. Therefore, many studies suggested LipL32 protein as a good candidate for development of leptospirosis detection kit because it is highly conserved and produced only in pathogenic Leptospira species. In this study, we aim to investigate the performance of our in-house ELISA using recombinant LipL32 to detect leptospirosis in Indonesia. Fourteen human sera were used in this study and the infection status were determine using MAT. The result showed that nine of eleven MAT positive sera were successfully recognized by LipL32 ELISA. The antibody binding to LipL32 was also confirm by immunoblot. There was one of three MAT negative sera has high OD above 0.5 in ELISA, but it showed negative reaction in immunoblot result. Overall, this study demonstrated that recombinant LipL32 protein can recognized antibody from human leptospirosis and can be used as a universal antigen to detect infection by any serovars of pathogenic leptospira.

Deteksi Gen Faktor Virulensi Escherichia Coli Patogen Resistan
Siprofloksasin Asal Usap Kloaka Ayam Layer
- Authors: Joen Firmanta Peranginangin
  Pages: 37 - 45
  Abstract: Avian Pathogenic Escherichia coli (APEC) is a cause of extraintestinal infections, particularly respiratory infections, pericarditis, and septicemia in poultry (colibacillosis). Research aimed at uncovering the virulence factors responsible for colibacillosis in poultry, especially laying hens in Indonesia, is still quite rare. The purpose of this study is to identify the virulence factors responsible for colibacillosis in E. coli strains resistant to ciprofloxacin. The virulence factors targeted in this research are the genes iss, iutA, iroN, ompT, and hlyF. The study utilized 327 E. coli isolates from the archives of the National Veterinary Drug Assay Laboratory, which were collected in 2021 in seven provinces.All isolates were tested for pathogenicity using Congo Red. Subsequently, E. coli strains determined to be pathogenic were tested for their sensitivity to ciprofloxacin using the agar dilution method. Isolates that were both resistant and pathogenic were then examined for the presence of the virulence genes using polymerase chain reaction (PCR). Based on the results of the Congo Red test, it was found that 59 isolates (18%) were pathogenic E. coli. Among the 54 pathogenic E. coli isolates subjected to sensitivity testing, 30 isolates were found to be resistant to ciprofloxacin. Subsequently, PCR analysis of these 30 ciprofloxacin-resistant pathogenic E. coli isolates revealed the presence of the iss gene in 29 isolates (96%), iutA in 23 isolates (76.6%), ompT in 19 isolates (63.3%), hlyF in 14 isolates (46.6%), and iroN in 11 isolates (36.6%). Eight isolates showed the presence of all five virulence genes, while the rest had one to three virulence genes. This study demonstrates that virulence genes are commonly found in ciprofloxacin-resistant pathogenic E. coli. This suggests a potential threat to the effectiveness of ciprofloxacin in managing colibacillosis in laying hens.

  Abstract: AbstrakPeriode kering pada sapi perah didefinisikan sebagai masa istirahat non laktasi sebelum melahirkan dengan tujuan utama meningkatkan produksi susu pada periode laktasi berikutnya. Saat ini secara umum antibiotika juga digunakan untuk terapi maupun pencegahan mastitis saat periode kering. Mastitis adalah salah satu penyakit menular yang paling penting pada sapi perah di seluruh dunia, bertanggung jawab atas kerugian ekonomi yang besar dan dampak negatif pada kesejahteraan sapi maupun manusia disebabkan oleh penurunan produksi susu. Salah satu metode yang digunakan untuk meningkatkan produksi susu pada laktasi berikutnya adalah periode kering yang berkisar antara 40-60 hari sebelum melahirkan. Guna menghindari kejadian mastitis saat periode kering maka saat ini banyak digunakan antibiotika saat memasuki periode kering atau akhir periode kering. Saat ini, sebagian besar dari antibiotika yang digunakan dalam industri susu diterapkan untuk mengendalikan mastitis pada sapi perah periode kering. Banyak Negara menerapkan system pemberian antibiotika pada semua kwartir saat periode kering. Namun demikian penggunaan antibiotika tersebut meningkatkan kekhawatiran munculnya resistensi antibiotika. Tulisan ini akan mencoba mengulas secara sederhana dampak penggunaan antibiotika saat periode kering pada sapi perah.Kata kunci : mastitis; periode kering; antibiotika; resistensi

  Abstract: Feline panleukopenia (FPL) is a viral infectious disease caused by the feline panleukopenia virus (FPV) that affects cats of all ages. Clinical symptoms that appear in each individual cat vary greatly, depending on age, immune status, and the presence or absence of secondary infection. The aim of this research was to diagnose the FPL based on clinical signs and polymerase chain reaction (PCR) in cat with various ages. This study used 15 cats that showed one of clinical symptoms including lethargy, anorexia, fever, diarrhea, and vomiting. All cats were examined physically and by PCR of blood, then analyzed descriptively. The results showed that 10/15 (66.7%) cats were <7 months, 4/15 (26.7%) were 7-12 months, and 1/15 (6.6%) was >1 year old. Identification by PCR showed that 100% of the samples positive, so that all of cats diagnosed FPL. Clinical signs that commonly appeared in this study included anorexia (80%), fever (80%), vomiting (73.3%), lethargy (66.7%), and diarrhea (40%). Young cats <7 months commonly showed anorexia, fever, vomiting, and lethargy, cats aged 7-12 months commonly showed anorexia, fever, vomiting, and diarrhea, cat aged >12 months experienced anorexia and vomiting. Concluded that the predominant clinical symptoms of FPL in young cats were anorexia, fever, vomiting and lethargy, whereas in adult cats anorexia, fever, vomiting, and diarrhea. Clinical symptoms can be used for initial screening of FPL, but the causative diagnosis needs to be determined by polymerase chain reaction.

Cytotoxic Activity Red Eye Snail (Cerithidea obtusa) Extract on Colon
Cancer Cell WiDr
- Authors: Wisnu Jaka Dewa
  Pages: 129 - 135
  Abstract: Based on data released by Globocan in 2020, the incidence of colorectal cancer is the fourth highest in Indonesia (8.6%) and the third in the world (10%). This disease is hard to treat because the available therapy is less effective. Therefore, it is necessary to develop effective alternative therapies, especially those originating from Indonesia's natural resources, easy to obtain and reproduce. This study aims to determine the potential of red eye snail extract as an anticancer through cytotoxicity tests with the MTT Assay method on colon cancer cells WiDr and DNA fragmentation tests with Hoescth staining. In this study, we used various concentrations of the red-eye snail extract to test with 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide (MTT) and doxorubicin reagents as positive controls. Absorbance values were read using a microplate reader at a wavelength of 595 nm. The cell absorbance data was converted into cell viability and probit analyzed to obtain the IC50 value. The results showed that the higher the concentration of the extract caused a decrease in the number of WiDr cells and an increase in damage to the structure of WiDr cells. Based on the results of probit analysis, it was found that the IC50 value of the extract was 36.28 µg/mL or classified as moderate cytotoxicity. The DNA fragmentation test showed that at concentrations of 125 ppm and 62.5 ppm, it was able to provide an effect similar to doxorubicin, namely triggering apoptosis in WiDr colon cancer cells.
