  • Intra-abdominal transmissible venereal tumor in a dog: a case report

    • Authors: Alexandre José Rodrigues Bendas, Pablo Luiz das Neves Moreto, Adriano Baldaia Coxo, Paula Gazé Holguin, Denise do Vale Soares
      Abstract: Transmissible venereal tumor (TVT) is a malignant round cell neoplasm that primarily affects the genital region of dogs. Despite being sexually transmitted, transmission can occur through contact with mucous membranes and cutaneous tissue. Although less routine, TVT has been described in several extragenital regions, such as the nasal plane, oral cavity, eyeball, eyelid, and anus. Although metastases are infrequent, they can occur in the skin, inguinal lymph nodes, liver, kidneys, spleen, intestine, heart, brain, lungs, and other organs. The clinical signs of TVT are usually related to serosanguineous secretion, intense odor, deformity, ulceration, and possibly areas of necrosis. In cases of metastases, clinical signs will depend on the affected organ. The treatment of choice for TVT is chemotherapy with vincristine. The present study aimed to report the case of a 2-year-old mixed-breed canine with intra-abdominal nodules detected by ultrasound examination, which were later diagnosed as a TVT by histopathology and immunohistochemistry.

  • Gastrointestinal Parasites in Sheep from the Brazilian Pampa Biome:
           Prevalence and Associated Factors

    • Authors: Natália Soares Martins, Carolina Caetano dos Santos, Sara Patron da Motta, Andrios da Silva Moreira, Nara Amélia da Rosa Farias, Jerônimo Lopes Ruas
      Abstract: Parasitic infections are common in sheep farming worldwide. A cross-sectional study was carried out to determine the prevalence and associated risk factors among gastrointestinal parasites and sheep herds from the Brazilian Pampa biome, Rio Grande do Sul state, Brazil. Twenty-one farms were visited, where rectal faecal samples were individually collected from 309 animals. The sheep industry on the studied farms was characterised by small farms with a low level of technification, an extensive grazing system and meat production. Of all samples analysed, strongyle nematodes had the highest prevalence (77.02%), followed by Eimeria spp. (70.55%), Moniezia expansa (20.39%) and Strongyloides papillosus (17.48%). Mixed infection, between helminths and protozoans, was detected in 68.61% of samples. All herds were positive for strongyle and Eimeria spp. A predominance of Haemonchus spp. and Trichostrongylus spp. nematodes was observed in the herds. Younger animals were significantly more affected by Eimeria and M. expansa. In the semi-intensive and intensive systems, a higher frequency of Eimeria and strongyle infections was observed. Parasite infection was significantly reduced at low animal densities. The Brazilian Pampa region presents a high prevalence of gastrointestinal parasites among sheep; age, breeding system and stocking density were factors associated with parasite infection.

  • Echocardiographic evaluation of working dogs of the Military Police of Rio
           de Janeiro: effects of the breed and body weight

    • Authors: Alex Moreira de Lima, Rodrigo Mencalha Moreira, Marcelo Salvador Gomes, Marcia Torres Ramos, Carlos Augusto dos Santos-Sousa, Paulo Souza-Júnior, Marcelo Abidu-Figueiredo
      Abstract: The Military Police of Rio de Janeiro state use dogs as a decisive tool for patrol and detection of drugs, weapons, and explosives. Complementary tests, such as echocardiography, are essential to maintain the integrity of these animals. This study aimed to evaluate the echocardiographic parameters of the working dogs belonging to the Military Police of Rio de Janeiro and compare them with the available data. Echocardiographic evaluation was performed on 48 healthy adult dogs from the Canine Action Battalion of the Military Police of Rio de Janeiro, Brazil. The sample consisted of 13 Labrador Retrievers, 12 Malinois Belgian Shepherds, 10 German Shepherds, 8 Dobermann Pinschers, and 5 Dutch Shepherds. Echocardiographic variables were correlated with body weight (BW). A positive correlation (P=0.0142, r=0.6837) between BW and the diameter of the left atrium was found in Malinois Belgian Shepherds. In German Shepherds, a positive correlation between BW and the internal diameter of the right ventricle during diastole (P=0.0320, r=0.6757) was observed; in addition, a positive correlation between BW and left ventricular internal diameter (P=0.0344, r=0.6689) during diastole was also found. Echocardiographic evaluations of these working dogs differed slightly from those previously established for similar-sized dog breeds.

  • MRI abnormalities in a severe cognitive impairment mimicking a forebrain
           lesion in a geriatric dog

    • Authors: Evelina Burbaitė, Aistė Gradeckienė, Dalia Juodžentė, Martinas Jankauskas
      Abstract: Canine Cognitive Dysfunction is a neurological condition, that causes dogs to experience a wide variety of clinical signs. On rare occasions the symptoms may be unusual and severe, therefore they reminiscent of another disease. In this case report a 16 year and 8-month-old intact female poodle presented with circling, head pressing, and generalized ataxia. Prior clinical and neurologic examinations indicated the neurolocalisation to be forebrain. Morphometric brain parameters in MRI indicated otherwise. Quantitative MRI parameters such as the ventricle-brain index, interthalamic adhesion thickness, area, and the ratio of the interthalamic adhesion thickness to brain height may aid in the diagnosis of CCD.

  • Hematological and biochemical values in Breton breed horses in

    • Authors: Fábia Fernanda Cardoso de Barros da Conceição, Brunna Helena Vidal de Mattos, Paula Aguiar Sá, Tatiana Guerrero Marçola, Gilmara Araújo da Silva, Heitor Castro Alves Teixeira, Rita de Cássia Campebell
      Abstract: Due to the scarcity of information on Breton horses, the objective was to study hematobiochemical values of this breed. Blood samples were collected from 29 Bretons, males and females, of different ages, in Brasília-DF, distributed into groups, according to age, without distinction of sex (G1): animals from 4 to 9 years old (n=16) and (G2): from 10 to 26 years old (n=13). The horses were also distributed into males and females for comparisons between the sexes. Values for red blood cells, hemoglobin, creatinine, and urea were statistically higher in females. Fibrinogen was higher in males. Lymphocyte values were higher in G1, but mean corpuscular volume, monocytes, neutrophils, and GGT in G2 were higher than G1. The hematocrit value differed between the ages of the females and was higher than that of the males, while the older male animals showed higher values than the young animals. Females presented lower platelet values than males, with older females having higher platelet values than younger females, in the same way as males. G1 females had the highest leukocyte values. The leukocyte values in males of G2 were higher than those of G1. This same behavior occurred for lymphocytes, eosinophils, and creatine kinase. Considering the albumin and aspartate aminotransferase variables, females had the highest values in the group of animals aged 4 to 9 years. Bretons are considered cold-blooded animals, which is consistent with the observed blood count values. However, it is concluded that these horses have biochemical values similar to warm-blooded breeds.
