|dc.description.abstract||The distribution of enterotoxin types and toxic shock syndrome toxin I (TSST-1) strains for 176 Staphylococcus aureus strains obtained from food samples and 62 S. aureus strains isolated from clinical samples were compared. It was found that for both the food and clinical isolates, staphylococcal enterotoxin A (SEA) strains accounted for the major part (75% and 45% of the total enterotoxigenic strains for food and clinical isolates, respectively) followed by SEE or SEAS, SEC and SED strains. For food isolates, none of the S. aureus strains was TSST-1 strain while for clinical isolates, Three strains (1 SEC, 1 SED and 1 SEAB strain) were found to be TSST-1 strains. When susceptibilities for These enterotoxigenic S. aureus strains to antibiotics, such as penicillin, oxacillin, vancomycin, methicillin, streptomycin, tetracycline, gentamycin and kanamycin were compared, results showed that 51.6% of the food isolates were resistant to penicillin G only bur sensitive to the other antibiotics tested. Also, 8 of the 64 enterotoxigenic strains isolated from food samples were ail sensitive to antibiotics while none of the enterotoxigenic strains from clinical samples showed this antibiotic susceptibility pattern. No methicillin resistant S. aureus (MRSA) strains could be found among the food isolates. On the other hand, the majority (42.4%) of the enterotoxigenic S. aureus strains from clinical samples were penicillin and/or other antibiotics resistant MRSA strains. Since MRSA strains often posed the therapeutic problem, the MRSA strains were further confirmed by PCR assay using the primers specific for mecA gene. It was found that results obtained from the disc agar diffusion method and the PCR method were the same. (C) 1998 Academic Press Limited.||en_US|
