The development of neoplasms in giant anteaters (Myrmecophaga tridactyla) is poorly documented, with most studies focused on non-neoplastic changes. This report describes a case of chondrosarcoma in a 15-year-old male captive giant anteater that presented with lameness for approximately 6 months, locomotion difficulties and swelling of the left thoracic limb. After review of a radiograph, humane euthanasia was decided due to the poor prognosis and quality of life.

Infectious Laryngotracheitis (ILT), caused by Gallid Herpesvirus 1 (GaHV-1), is a contagious and notifiable disease. In Santa Catarina, southern Brazil, it was exotic until 2020, when it was diagnosed in a commercial layer farm in São Ludgero/SC. This study consists of two phases: the first assesses ILT prevalence in municipalities near São Ludgero in 2020, while the second examines the entire state of Santa Catarina in 2021.

Article Synopsis
  • - The study details rare cases of skin tumors in Brazilian rainbow boas, identifying conditions similar to hemangioma and hemangioendothelioma, and examining possible links to boid inclusion body disease (BIBD).
  • - Thirteen snakes exhibited the skin lesions, with a mix of introduced animals and those bred in-house; lesions emerged over eight years, but no new cases were recorded in the last five years.
  • - Diagnostic tests confirmed BIBD in five snakes, alongside the presence of reptarenavirus in the tumors, suggesting a potential connection between the virus and the observed neoplastic conditions, warranting further research.

are responsible for proventricular dilatation disease (PDD) in psittacines. This study aimed to determine the occurrence and factors associated with infection in psittacines kept in captivity in a state in the southern region of Brazil. A cross-sectional study was carried out with 192 birds from two facilities (A and B) in 2019, using choanal, esophageal, and cloacal swabs and feathers, totaling 768 samples subjected to reverse-transcription polymerase chain reaction (RT-PCR), for the matrix (M) protein gene with a final product of 350 base pairs (bp).

Neosporosis and toxoplasmosis are important parasitic causes of abortions in small ruminants. This study verified the occurrence of these diseases in sheep fetuses from Santa Catarina State, Southern Brazil from 2015 to 2022. Sheep fetuses were necropsied with organ sampling for histopathology, and polymerase chain reaction (PCR) for Neospora caninum and Toxoplasma gondii using the Nc5 and SAG2 targets, respectively, in frozen brain tissue.

In this study, we describe an outbreak of toxoplasmosis in an enclosure of five Callithrix penicillata in Southern Brazil. The marmosets were found dead and submitted to necropsy and histopathology. Liver, spleen, and lungs were frozen and sent for polymerase chain reaction (PCR) and nested-PCR-restriction fragment length polymorphism (RFLP) genotyping of Toxoplasma gondii.

We characterized bovine viral diarrhea virus (BVDV)-related abortions in cattle and identified the species and subgenotypes in the state of Santa Catarina, southern Brazil. Our RT-PCR assay was positive for BVDV in 5 fetuses from different farms; however, 3 of the 5 fetuses were also PCR-positive for . In the 5 BVDV-positive fetuses, gross lesions included fetal mummification (1), hepatomegaly (1), subcutaneous edema (1), and perirenal edema (1).

Background And Aim: Flemish cattle in Brazil are on the brink of extinction and are found only in one herd in Lages, Santa Catarina State. This study aimed to uncover the reasons for the recurring abortions in the Flemish cattle herd.

Materials And Methods: Seventeen Flemish fetuses underwent postmortem examinations, with samples collected for histopathology and microbiology culture tests, polymerase chain reaction (PCR) test for , and reverse transcription-PCR (RT-PCR) test for bovine viral diarrhea virus (BVDV) from 2015 to 2020.

A case of non-communicating hydrocephalus and microcephaly in a sheep fetus infected with Neospora caninum from Lages, Santa Catarina, Brazil, is reported. Macroscopically, there was moderate flattening and narrowing of the skull, and the portion of the cerebral hemispheres was markedly reduced in size, measuring 3.5 × 3.

A cross-sectional study was conducted in 274 cats for determination of FeLV antigenemia and FIV seropositivity and factors associated with those infections in cats presented at the Veterinary Hospital of the Santa Catarina State University - UDESC (Brazil). Apparent prevalence for sick cats at the hospital population was 28.41% (95%CI 21.

The vertebral heart score or size (VHS) measurement is routinely used to provide a more objective measurement of cardiomegaly in dogs. However, breed or body conformation can influence the VHS. To assess the specific VHS for the Australian Cattle Dog, left-to-right lateral, right-to-left lateral, dorsoventral and ventrodorsal thoracic radiographs from 20 individuals free from cardiac and pulmonary disease were obtained.
