title: Detection of superantigenic toxin genes in Staphylococcus aureus strains from subclinical bovine mastitis.
abstract: The aim of this study was to determine the presence of genes encoding enterotoxins (sea-sej) and toxic shock syndrome toxin-1 (tst) of Staphylococcus aureus strains (n = 130) isolated from subclinical bovine mastitis in Turkey by polymerase chain reaction. Sixty-one (46.9%) isolates were found to contain one or more toxin genes. The most frequently found enterotoxin genes were seg (16.2%) and sei (16.2%), followed by sec (15.4%), sed (10.8%), and sej (10.8%), respectively. The tst gene was detected in seven (5.4%) isolates. None of S. aureus strains harbored sea, seb, see, and seh genes. Since these toxins are recognized agents of staphylococcal food poisoning, it must be considered that the consuming raw milk and raw milk products would pose public health risk as high prevalence of toxigenic S. aureus was found in this study.
