Sixty-nine Staphylococcus aureus strains. 39 of which produced staphylococcal enterotoxin B (SEB + ) and 14 of which were associated with toxic shock (TS + ), were studied using the following markers: serotyping, phage typing, antibiotyping. ribotyping, zymotyping and pulsed-field electrophoresis typing. Analysis of the results showed that the enterotoxin B producing strains were derived from at least three clones: the first two consisted of methicillin-susceptible strains, while the third included the methicillin-resistant (MRSA) strains. TS+ strains of non-genital origin appeared to be distributed between the three clones, with no specific characters.
