Conteúdo: | Abstract: Staphylococci isolated from mastitic goat's milk in 29 Brazilian dairy herds were analyzed for the production of alpha, beta and delta-hemolysin on sheep and horse red blood cells. Of the total strains studied, 80% demonstrated hemolytic activity. Among coagulase-negative staphylococci (CNS) isolated from subclinical mastitis, 65.2% produced alpha-hemolysin, 19% beta-hemolysin and 83.3% delta-hemolysin, either alone or combined. Staphylococcus aureus isolates showed hemolytic activity for all hemolysin types studied-76.7% of them produced alpha-hemolysin, 74.4% beta-hemolysin and 83.7% delta-hemolysin, either alone or co-produced. The results suggest that goat's mammary glands are an important reservoir of hemolytic staphylococci
