豚の心内膜炎よりのレンサ球菌分離

抄録

Bacterial endcarditis caused by streptococci has frequently been seen among swine examined in slaughterhouses. The authors encountered 21 swine cases of streptococcal endocarditis over a period from Apil, 1968, to March, 1970. They isolated α-type streptococci from 10 cases, β-type ones from 5 cases, and γ-type ones from 4 cases. Two types, α and β, were isolated from 1 case. One case could not be assorted.
Two cases of endocarditis were proved to have been caused by mixed infection with streptococci and other pus-forming organisms.
