Produção de enterotoxinas e da toxina da síndrome do choque tóxico por cepas de Staphylococcus aureus isoladas na mastite bovina

Abstract

A total of 72 strains of Staphylococcus aureus were examined for the production of staphylococcal enterotoxins (SE) A, B, C, D and toxic shock syndrome toxin (TSST-1). The strains were isolated from milk samples from cows with mastitis in dairy herds of São Paulo State, Brazil. Off 72 isolates, 38 (52.8%) produced SEA, 38 (52.8%) SEB, 32 (44.4%) SED, 28 (38.9%) SEC and 27 (37.5%) TSST-1. From the 72 strains, 66 (91.7%) produced, at least, one or more toxin, including TSST-1.
