Chemodectomas are malignant or benign neoplasms of chemoreceptor cells, which are commonly located in the base of the dog’s heart. This paper reports a case of chemodectoma in an 11 years old male dog of Fila Brasileiro breed, in Uberaba city. The animal has a frequent cough, dyspnea and members edema. Carotid body chemodectoma was diagnosed on lung areas, liver, spleen and pancreas metastases. The chemodectoma causes still unknown, but most of affected animals, has a chronic respiratory disease, associated with the neoplasms.
Vaccinia virus (VACV) is the etiologic agent of bovine vaccinia, an emerging zoonotic disease with potential health issues for dairy herds and humans. VACV may occasionally infect other species, including horses. In this sense, an outbreak of VACV disease in horses was described in Pelotas, RS, in 2008, where a co-infection with two VACV strains (named
A verminose é uma enfermidade que provoca anemia e depalperação. O Tretameres americana por se localizar no proventrículo ocasiona proventriculite com edema da parede do proventrículo e hipotrofia muscular. O presente trabalho relata um caso de verminose em aves domésticas, ocorridas na região de Uberaba -MG.
The aim of this study is to characterize macro and microscopic changes in uterine fallopian tubes of embryo donors previously submitted to a series of follicular punctures, created in the Uberaba-MG region. Due to the difficulty in confirming pregnancy, 33 female bovine oocytes were sent for slaughter by follicular aspiration. Their reproductive devices were separated and the right and left tubes were evaluated. In the histopathological evaluations were found 30 alterations being: 43% (13/30) of acute salpingitis, 33% (10/30) acute catarral salpingitis, 17% (5/30) chronic salpingitis, 3% (1/30) desquamation of Epithelium and 3% (1/30) mucosal degeneration. With the present work it can be inferred that continuous follicular aspiration in bovine females promotes lesions seen under light microscopy in the uterine tube, such as acute, catarrhal and chronic salpingitis, mucosal degeneration and scaling of the epithelium. These lesions may be results of lesions that started in the uterus and / or promoted by the puncture of adjacent structures leading to the reduction of the fertility of these animals.
RESUMO.Objetiva se com este trabalho avaliar as alterações macroscópicas e microscópicas de ovários em vacas doadoras zebuínas. Ponderou-se o trato reprodutivo de 62 fêmeas zebuínas (Bos taurus indicus) doadoras de oócitos pelo método de punção folicular, animais provenientes da região de Uberaba-MG. Nas lesões Macroscópicas, foram encontrados 75,47% de cisto, 0,94% de cicatriz lateral e 23,58% de fibrose. Nas avaliações histopatológicas foram encontrados 24,
