چکیده انگلیسی
Staphylococcus aureus recovered from nasal carriers, producers and non-producers (43 isolates each) of classical pyrogenic toxin superantigens (PTSAgs), were screened for 17 additional PTSAg-genes by PCR. Percentages of 88.4 and 65.1 were positive for some new enterotoxin-gene, and 76.7 and 55.8 for enterotoxin-gene-clusters (egc-like), respectively. The 86 isolates belonged to 17 toxin-genotypes (all eta-, etb-, etd-, see- and sep-negative), and generated 40 SmaI-genomic profiles that in a dendrogram of similarity (S⩾0.7) clustered into nine lineages and 11 non-clustered branches. Correlations between classical PTSAgs and SmaI-lineages were established and egc-like groupings appeared dispersed in six lineages.
