| Abstract;In a feedlot farm in Hiroshima Prefecture, a 15-month-old Holstein steer died of anemia. An autopsy revealed that a white verruca measuring 7cm in diameter in the heart was attached to the tricuspid valve. Histopatho-logically, necrosis, hemorrhage, neutrophil aggregation, fibrinous effusion, and proliferation of gram-positive coccus in the verruca were observed. Gram-positive coccus at 10'7'CFU/g was isolated from the verruca, as a pure culture. The isolated bacteria were identified as Helcococcus ovis based on the 16S rDNA sequence and biochemical features. On immunohistochemical staining using an antiserum prepared from the bacterial isolate as the antigen, positive reactions were observed diffusely in the verruca. This is the first case in Japan in which H. ovis was isolated from an ox with valvular endocarditis. (author abst.) |
