Production of enterotoxins and toxic shock syndrome toxin by Staphylococcus aureus isolated from bovine mastitis in Brazil.
The production of toxic shock syndrome toxin 1 (TSST-1) and enterotoxins (SE) A, B, C and D by bovine mastitis isolates of Staphylococcus aureus was evaluated by immunodiffusion using the Optimum-Sensitivity Plate method. S. aureus strains were isolated from bovine mastitis in 23 dairy herds in the state of Minas Gerais, Brazil, during 1994-9. Of 127 isolates, 83 (65.04%) produced one or several toxins, and among them production of SE was found in 54 (43.0%) isolates, of which 1138 (29.09%) secreted enterotoxin identified as type D. TSST-1 was found in 5829 (45.723.0%) isolates.
