| Descreve-se um caso de aborto eqüino por Leptospira sp. em um feto de 6 meses proveniente de um estabelecimento localizado próximo a Porto Alegre/RS. As lesões macroscópicas se caracterizaram por icterícia e hemorragias distribuídas difusamente sobre a pele, mucosa oral, tecido subcutâneo, pulmão, coração e sistema gastrintestinal. O fígado estava aumentado de tamanho, friável e de coloração amarelada. Os rins apresentavam hemorragias petequiais na superfície capsular e na superfície de corte observaram-se palidez da região cortical e medular. Cortes de rim e sistema nervoso central, corados por Warthin-Starry, revelaram a presença de espiroquetas nos túbulos, glomérulos e substância branca do encéfalo. Cultivo aeróbio de amostras de fígado e pulmão não... |

| A leishmaniose visceral canina é uma doença grave e a morte ocorre por falência renal, considerando que os métodos diagnósticos convencionais não possibilitam a classificação clínica do animal. O objetivo deste estudo foi associar a carga parasitária renal aos achados clínicos e histopatológicos em cães com leishmaniose visceral. A análise microscópica revelou predomínio de nefrite intersticial mononuclear de graus variados em 59,3% dos cães avaliados. Entretanto, não houve diferença entre a carga parasitária renal de sintomáticos e oligossintomáticos (P= 0,35). As lesões renais foram de ordem inflamatória e a quantidade de parasitos não influenciaram na característica dessas lesões e nem nas alterações bioquímicas, mesmo em cães com diferentes... |

| Cholangiocarcinomas are neoplasms that originate from the bile duct epithelium. The present case described a cholangiocarcinoma in an adult female American Rhea (Rhea Americana araneipes) by means of gross, histopathology and immunohistochemistry. Irregular, firm, multifocal, yellow-white masses, measuring from 0.4 to 6cm in diameter were observed in both liver lobes. At the cut surface, multiple firm nodules filled with connective tissue were present. Microscopically, the neoplasia was composed of small, irregular, gland-like structures of neoplastic cells surrounded by connective tissue. The cells resembled epithelial cells of the hepatic biliary ducts. Neoplastic cells were positive for cytokeratin and negative for vimentin. This is the first report of... |

| ABSTRACT: Pythiosis in felines is a rare disease associated with the oomycete Pythium insidiosum. The aim of this report was to describe the macroscopic, histopathological, and molecular characteristics of P. insidiosum infection in a 2-year-old cat, with a localized invasive subcutaneous mass. The feline had an increase of volume near the anal region since it was younger. The cat died just after surgery. The necropsy was performed, and samples were collected for histopathological examination. Microscopically, the skin lesion was characterized by necro-eosinophilic dermatitis, panniculitis, and myositis surrounding negatively stained hyphal structures. In the sections stained with GMS, dark brown hyphae were clearly seen inside the affected tissue. They... |

| ABSTRACT: Amorimiapubiflora (Malpighiaceae), which contains sodium monofluoroacetate (MFA) is the main cause of "sudden death" in cattle in the Brazilian state of Mato Grosso. This research investigated the induction of resistance to the poisoning in sheep by the continuous administration of non-toxic doses of the plant and also the possibility to transfer this resistance to other sheep by the transfaunation of ruminal fluid. For this a group of four sheep (G1) received daily doses of 0.5g kg-1 for 20 days and after an interval of 15 days were challenged with three daily doses of 1g kg-1 for 3 days. Also the transfer of resistance to A. pubiflora poisoning was evaluated by transfaunation of rumen fluid (100ml for 10 days) from G1 sheep to five sheep (G2),... |

| A infecção por Erysipelothrix rhusiopathiae tem distribuição mundial e se caracteriza por lesões de pele, endocardite vegetativa, artrite e problemas reprodutivos tais como aborto, nascimento de animais mortos e diminuição do tamanho da leitegada. Áreas circulares bem delimitadas e esbranquiçadas localizadas na pele ao redor dos olhos, face, escápula e trem posterior foram as principais alterações macroscópicas observadas em um feto suíno da raça Large White. Microscopicamente, essas lesões apresentavam perivasculite mononuclear multifocal moderada associada com bastonetes Gram-positivos. Os cultivos aeróbios de amostras de fígado, pulmão, conteúdo estomacal e pele revelaram crescimento de Erysipelothrix rhusiopathiae. |

| A two-month-old lamb showing signs of severe neurological disease characterized by muscular tremors, hypermetria, and motor incoordination was submitted to the Veterinary Pathology Laboratory - Universidade Federal do Rio Grande do Sul, Brazil. At necropsy, the major findings were a marked reduction of the size of the cerebellum and bilateral dilatation of the lateral ventricles. Microscopically, areas of cellular disorganization in the cerebellar cortex, reduction of the granular layer of cerebellum associated with decreased density of cells, and the presence of large cytoplasmic vacuoles in the molecular layer were observed. Neurons of the gray matter of the brain and macrophages of the mesenteric lymph nodes stained positively by the... |

| ABSTRACT: The aim of this report is to describe the clinical, pathological and imaging findings and treatment of colitis caused by Pythium insidiosum in a canine presenting haematochezia and progressive weight loss. Through imaging, a thickening of the transverse and descending colon was observed. Histopathological analysis of the large intestine fragment revealed the presence of hyphae, confirmed by immunohistochemistry and PCR as P. insidiosum. Antifungal treatment with itraconazole implemented after partial surgical resection, resulted in control of the disease. |
