Bacterial isolation from slaughtered pigs associated with endocarditis, especially the isolation of Streptococcus suis.
Bacterial isolation from slaughtered pigs with endocarditis was carried out from 1985 to 1994. A total of 495 (0.025%) out of 2,006,127 pigs were diagnosed as having endocarditis. Though bacteria were significantly isolated from 399 of the 495 pigs, bacteria could not be isolated in 96 pigs (19.4%). In 11 pigs, 2 bacterial species were isolated from heart lesion. Streptococcus suis was isolated from 127 cases (25.7%), Streptococcus dysgalactiae from 75 (15.2%), Erysipelothrix rhusiopathiae from 63 (12.7%), Actinomyces pyogenes from 39 (7.9%), Pasteurella multocida from 11 (2.2%). Staphylococcus aureus from 10 (2.0%), and Streptococcus porcinus from 8 (1.6%). Among the 99 isolates biochemically identified as S. suis, the major serotype was S. suis type 2 (35.4%). The remainder of the typable isolates were identified as serotypes 1/2 (2.0%) and 9 (1.0%). A total of 61 isolates (61.6%) were untypable.
