| Abstract: | One hundred and one pig abscesses of different localisation were examined. Bacteria were re-covered from all abscesses. In 6’8 abscesses a mixed aerobic and anaerobic flora was found. In 22 abscesses solely aerobes and in 11 solely anaerobes were found. Gorynebaoterium pyogenes and Fuso-bacterium necrophorum were found in 61 and 45 abscesses, respectively. Hemagglutination litres of G. pyogenes strains were higher with pig erythrocytes than with sheep erythrocytes. Three of 4 isolates of Staphylococcus aureus produced enterotoxin type A.Key words: pig abscess, Corynebacterium pyogenes, Fuso-bacterium necrophorum, hemagglutination |
