Clonal study of enterotoxin-B producing strains of Staphylococcus aureus

Epidemiol Infect. 1994 Jun;112(3):501-11. doi: 10.1017/s0950268800051207.

Abstract

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 nongenital origin appeared to be distributed between the three clones, with no specific characters.
