ABSTRACT
O tumor venéreo transmissível (TVT) é uma neoplasia canina de elevada incidência e relevância clínica. A transmissão decorre da transplantação de células neoplásicas durante o acasalamento, lambedura, mordedura ou farejamento das regiões acometidas. O diagnóstico baseia-se nos sinais clínicos e exames laboratoriais (exame citológico / exame histopatológico / exame imuno-histoquímico). Diferentes tratamentos (excisão cirúrgica /radioterapia / quimioterapia) são recomendados. O quimioterápico sulfato de vincristina apresenta-se eficaz. Este trabalho teve como objetivo relatar um caso de TVT canino. Uma cadela, sem raça definida (SRD), pesando 9 kg, não castrada, apresentou ao exame clínico ondulações e sangramento progressivo na região genital, além de um nódulo localizado na glândula mamária inguinal direita, sugestivo de TVT. A mesma foi submetida a exames laboratoriais (hemograma completo/exame bioquímico), exame citológico e exame ultrassonográfico abdominal. O diagnóstico citológico confirmou a suspeita de TVT. O quimioterápico sulfato de vincristina na dose de 0,05 mg/kg administrado por via intravenosa quatro vezes a intervalos semanais foi utilizado no tratamento. O diagnóstico citológico após o tratamento demonstrou ausência de células neoplásicas. Em conclusão, o tratamento do TVT utilizando o quimioterápico sulfato de vinscristina demonstrou-se eficaz.(AU)
Transmissible venereral tumor (TVT) is a canine neoplasm of high incidence and clinical relevance. Transmission results from the transplantation of neoplastic cells during mating, licking, biting or sniffing of the affected regions. The diagnosis is based on clinical signs and laboratory tests (cytological examination / histopathologic examination / immune histochemical examination). Different treatments (surgical excision / radiotherapy /chemotherapy) are recommended. The chemotherapeutic vincristine sulfate is effective. This study aimed to report a case of canine TVT. A dog, without defined breed (SRD), weighing 9 kg, uncastrated, presenting nodulations and progressive bleeding in the genital region, in addition to a nodule located in the right inguinal mammary gland, suggestive of TVT. The dog was submitted to laboratory tests (complete blood count/biochemical examination), cytological examination and abdominal ultrasound examination. The cytologic diagnosis confirmed the suspicion of TVT. The chemotherapeutic vincristine sulfate at a dose of 0.05 mg/kg administered intravenously four times at weekly intervals was used in the treatment. The cytological diagnosis after treatment showed absence of neoplastic cells. In conclusion, the treatment of TVT using the chemotherapeutic vinscristine sulfate has been shown to be effective.(AU)

In captivity, the energy demands reduce substantially in relation to the needs in free life. The assessment of the animal's weight is important to measure whether the level of activity and food supply are adequate. The weights of 14 psittacids were analyzed, being two Anodorhynchus hyacinthinus, one Ara ararauna, three Ara chloropterus, one Ara macao, six Amazona aestiva and one Aratinga jandaya. For the species of psittacans analyzed, a decrease in weight from the period from the first collection to the fourth collection was observed for most of the animals,. Changes in the size of the enclosures and social interactions with other species, given the mixed enclosures, may have influenced, both by calorie burning and perhaps by dispute in access to food, respectively.(AU)
