Abstract
SUMMARYThe production of enterotoxins A, B, C and F by strains ofStaphylococcus aureusisolated from various clinical sources and from isolates implicated in food poisoning was investigated.One hundred and ninety one of the 374 clinical strains (51·1%) were found to be enterotoxigenic; of these, 81 (27·7 %) strains produced enterotoxin A, 57 (15·3 %) strains produced enterotoxin B, 23 (6·2 %) strains produced enterotoxin C, and 64 (17·1 %) strains produced enterotoxin F. These enterotoxigenic strains were most frequently lysed by phages of group III (21·5%) or were not typable (22%).Eighteen of the 29 strains implicated in food poisoning were enterotoxigenic.The correlation of antigens and bacteriophage patterns with enterotoxigenicity was determined: enterotoxin A being related to a4antigen, enterotoxin B to phages of 94/96 complex with c1, o antigens, and enterotoxin F to phages of group I with 2632, k1k2, m antigens.
