Occurrence of the enterotoxin gene cluster and the toxic shock syndrome toxin 1 gene among clinical isolates of methicillin-resistant Staphylococcus aureus is related to clonal type and agr group.

Abstract excerpt

Analysis of 177 methicillin-resistant Staphylococcus aureus (MRSA) strains for the presence of egc and tst revealed that 60 strains carried at least one of the tested genes. MRSA strains were classified by pulsed-field gel electrophoresis into four clones belonging to agr groups I and III. Toxin genotypes were related by clonal type and agr group.
