Canine otitis externa is a common and recurrent disease in domestic dogs. Although not being life threatening, it can result in the overuse of antibiotics, increased bacterial resistance and reduction of options for treatment. This study aimed to determine: the principal characteristics (age, race, and gender) of dogs affected by otitis externa; the most frequently bacteria identified as being associated with it and their antimicrobial resistance profiles. A total of 221 bacterial isolates were identified by morphological staining and biochemical processes and tested against eleven antibiotics. Among the 148 dogs diagnosed with otitis externa, 51.4% (76/148) were males and 48.6% (72/148) females. The cases were detected mainly in dogs with age above 7 years (54.7%; 81/148. Among the races examined, poodles were the most numerous (14.84%; 22/148). The most common bacteria found were: coagulase-negative Staphylococcus (StCN), 33.9% (75/221); coagulase-positive Staphylococcus (StCP), 19% (42/221); Proteus spp., 17.2% (38/221) and Pseudomonas aeruginosa, 9.5% (21/221). Simultaneous resistance to more than three classes of antimicrobials were most frequently detected in P. aeruginosa (61.9%; 13/21) and Proteus spp (39.47%; 15/38). According to data obtained from this study, two veterinary medications found to be most effective for topical treatment were tobramycin and ciprofloxacin.

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.

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.

ResumoO presente trabalho relata um caso de cirrose biliar em um felino de três anos e meio, sem raça definida, na região de Uberaba-MG. O quadro clínico manifestado pelo animal foi apatia, desorientação, hiporexia e polidipsia, anúria, cegueira, mucosas hipocoradas com leve desidratação. Na necropsia os achados macroscópicos encontrados foram: hidroperitônio, hidrotórax, hidropericárdio, edema pulmonar, esôfago avermelhado, rins com nefrose colêmica e cirrose hepática. Achados microscópicos: cirrose biliar e glomérulonefrite. Cirrose biliar é uma apresentação da evolução de colangiohepatite. Por meio deste relato descrevemos os aspectos clínicos e patológicos desta patologia. Palavras-chave:Fígado, Felis domesticus, insuficiência hepática.
