A diseased Japanese Black Cow was carried into our laboratory in August 2011. The cow had developed verrucous endocarditis, pulmonary thrombosis, petechial hemorrhage in the kidney. Gram-positive streptococci were isolated from lesions of the verrucous endocarditis and pulmonary thrombosis. The 16S rRNA gene sequence analysis and coagglutination tests with sera for serotyping showed that these isolates were Streptococcus suis serotype 33. The present case was the first report of bovine endocarditis caused by S. suis serotype 33 in the world.
