Ocorrência de pneumonia associada à infecção por Mannheimia haemolytica em ovinos de Minas Gerais

Abstract: O trabalho descreve um surto de pneumonia em ovinos em uma propriedade na região central de Minas Gerais. Clinicamente os animais apresentavam apatia, mostravam dificuldade respiratória durante dois ou três dias ou morriam subitamente. À necropsia as alterações pulmonares eram similares em todos os ovinos. Havia consolidação dos lobos craniais e da parte ventral dos lobos caudais e ao corte fluía exsudato mucopurulento da traquéia e dos brônquios.

“…However, reports of subclinical caprine mastitis related to this agent have been found 79 . In Brazil, in the state of Minas Gerais, isolation and identification were carried out of M. haemolytica bacteria as a causative agent of pneumonia in ovines 80 . Species of the genus Trueperella are known to be important opportunistic pathogens in livestock and domestic animals, causing a variety of infections 81,82 , as well as mastitis and uterine infections in cows 83,84 .…”

“…Os casos de pleuropneumonias, broncopneumonias e pneumonias fibrinonecrosante ou fibrinossupurativa sem causa definida podem estar associados à infecção por Mannheimia haemolytica (antiga Pasteurella haemolytica) ou por doenças virais, como a língua azul (Araújo et al 2009;Antoniassi et al 2010). Entretanto, os fragmentos coletados durante a necropsia foram apenas conservados em formol, viabilizando somente o exame histopatológico.…”
