[Disorders in slaughtering animals. V. Endocarditis in slaughtering pigs, sows and cattle]

Bacteriological studies were done in 673 slaughtered animals (pigs, sows and cattle) in which post-mortem examination had revealed the presence of endocarditis. The studies were positive for the presence of bacteria in 453 cases. Lesions were not observed on ante-mortem inspection in 386 cases. Isolation of Corynebacterium pyogenes was extremely common in cattle, whereas beta-haemolytic streptococci and Erysipelothrix insidiosa were very frequently isolated in slaughtered pigs.
