RESUMO
Multiplex PCR was used to investigate the presence of enterotoxins genes (sea, seb, sec, sed and see) and femA gene (specific for Staphylococcus aureus) in coagulase-positive staphylococci (CPS) isolated from cheese and meat products. From 102 CPS isolates, 91 were positive for femA, 10 for sea, 12 for sed and four for see.
PCR multiplex foi empregado para investigar a presença de genes de enterotoxinas estafilocócicas (sea, seb, sec, sed e see) e do gene femA, específico para S.aureus, em cepas de estafilococos coagulase positiva (ECP) isoladas de queijos e derivados cárneos. De 102 cepas, 91 foram positivas para femA, 10 para sea, 12 para sed e 4 para see.
