Sažetak
The aim of this study was to determine the ability to produce enterotoxins and enterotoxin types A through E produced among S. aureus isolated from bulk tank milk in Fars, Iran by enzyme-linked immunosorbent assay. From September 2010 to July 2011 a total of 200 cow (n = 50), sheep (n = 40), goat (n = 40), camel (n = 30), and buffalo (n = 40) bulk milk samples were collected from 46 randomly selected herds in Fars provinces, Iran. In this study, 22 of 200 raw milk samples (11.0%) were found to be contaminated with S. aureus. The highest prevalence of S. aureus was found in buffalo milk (17.5%), followed by cow (16.0%), sheep (10.0%), goat (7.5%), and camel (3.4%). The ability to synthesize classical enterotoxins was found in 15 of 22 (68.2%) isolates. Six isolates (27.3%) produced SEA, 4 isolates (18.2%) produced SEC, 3 isolates (13.6%) produced SED, 1 isolate (5.0%) produced SEB, and 1 isolate (5.6%) produced both SEA and SEC (5.0%). No SEE was identified in raw milk samples. This study indicates that the presence of enterotoxigenic S. aureus in raw milk may contribute to the sources of staphylococcal food poisoning in Iran.
