RESUMO
ABSTRACT: This report aimed to describe the clinical, epidemiological and pathological aspects of an outbreak of rabies in buffaloes in Rio Grande do Sul (RS), Brazil. Seven out of 41 buffaloes from the same farm became fatally ill; they showed the clinical signs of ataxia, ascending paresis, and paralysis of the limbs. During necropsy, marked hyperemia of the leptomeningeal vessels, and severe distention of the urinary bladder were noted. Histologically, there were indications of nonsuppurative meningoencephalitis and ganglioneuritis with intracytoplasmic and eosinophilic inclusion bodies in the neurons. The fluorescent antibody test was positive for rabies. Viral antigens were also detected by immunohistochemistry (IHC) in sections of the cerebellum. These results allowed for the definitive diagnosis of rabies, which is uncommonly reported in buffaloes.
RESUMO: Este relato objetiva descrever os aspectos epidemiológicos, clínicos e anatomopatológicos de um surto de raiva em bubalinos no Rio Grande do Sul (RS), Brasil. Adoeceram e morreram sete de um total de 41 búfalos de uma mesma propriedade, com sinais clínicos de incoordenação motora, paresia ou paralisia ascendentes dos membros. Durante a necropsia, observou-se marcada hiperemia dos vasos das leptomeninges e acentuada distensão da vesícula urinária por urina. Histologicamente havia meningoencefalite e ganglioneurite não supurativas associadas a corpúsculos de inclusão intracitoplasmáticos e eosinofílicos em neurônios. O teste de imunofluorescência direta foi positivo para raiva. O antígeno viral também foi detectado em seções do cerebelo por meio da imuno-histoquímica (IHQ). A associação destes resultados permitiu o diagnóstico definitivo de raiva, uma doença pouco relatada em bubalinos.
RESUMO
Pitiose cutânea equina (PCE) é uma enfermidade descrita em todo território brasileiro, no entanto são escassas as informações quanto ao tratamento e procedimento cirúrgico em éguas gestantes. Descreve-se um caso de PCE em uma égua com nove meses de gestação com histórico de trauma no membro pélvico esquerdo que evoluiu para lesão ulcerativa granulomatosa com presença de kunkers. Foi realizada excisão cirúrgica, seguida da cauterização e perfusão regional intravenosa (PRI) com 50 mg de anfotericina B (10 ml) diluído em solução dimetilsulfóxido (DMSO) 10% (6 ml DMSO em 44 ml de Ringer com Lactato). Após 14 dias da intervenção cirúrgica, nova PRI foi realizada. O diagnóstico de PCE foi confirmado através da avaliação histopatológica e imuno-histoquímica. A égua pariu um potro saudável após dois meses da intervenção cirúrgica e recebeu alta após a completa epitelização da ferida.

RESUMO
Background: Aspergillus fumigatus is considered the major agent of mycotic diseases in birds, affecting mainly the respiratory tract. It is a disease of economic importance in the poultry industry, however it is not a zoonotic or contagious disease. Aspergillus spp. are an environment residents. Infection usually occurs by inhalation of conidia released by molds, which come off the diet or specifi c ingredients, the nest and contamination of eggs during incubation. The objective of this study is to relate the macro and microscopic diagnosis of aspergillosis in poultry.Discussion: The occurrence of aspergillosis depends on the dose of inhaled conidia of the fungus and the susceptibility of the host, which occurs in birds in the fi rst weeks of age, making it more resistant to infection in adults. The history of signs consisting of respiratory distress associated with stressful situations or the recent lack of response to antibiotics may provide support to the clinical diagnosis of aspergillosis. The isolation and identifi cation of the fungus comprises the best method to confi rm the disease agent. Histopathology provides an important contribution to the morphological diagnosis of the lesion and the fungus. The treatment of aspergillosis in poultry production is diffi cult and uneconomical, so that all attention is focused on prevention and control in poultry houses and hatcheri

The objective of this study is to relate the macro and microscopic diagnosis of aspergillosis in poultry.Case: In an intensive farming of poultry (Gallus gallus), it was observed mortality rate exceeding 20%, hoarseness and diffi culty breathing in males of approximately two weeks of age. The batch was treated with Terramycin ® (oxytetracyclinehydrochloride) in the fi rst week and Trissulfi n® (sulfamethoxazole, trimethoprim and bromhexine hydrochloride) in the second week. Birds were sent for analysis at the Laboratório Central de Diagnóstico de Patologias Aviárias (LCDPA) of the Universidade Federal de Santa Maria (UFSM). Necropsy was performed in three affected birds and pulmonary aspergillosis was suspected due to local pulmonary and disseminated injuries in the coelomic cavity, associated to the clinical signs. In birds assessed by necropsy examination, it was common the visualization of nodules in the internal
