Molecular screening of Staphylococcus aureus enterotoxins associated with samples of meat / Iraq

Abstract

Staphylococcus aureus secreted many types of toxins accompanying Intestinal poisoning resulting from eating food contaminated with bacteria or their toxins. Five hundred meat samples were collected from local markets, including fresh, frozen, canned, sausage and hamburger to investigate their contamination with S.aureus and then determined their ability of these isolates to secrete enterotoxins by using polymerase chain reaction. The results showed that the ratio of isolated S.aureus is 30 (6%) and the percentage of encoding genes for toxins is 30(100%), 0(0%), 3(10), 0(0%),0(0%),3(10), 2(6.7), 1(3.3), 0(0%) and 3(10) to sea, seb, sec, sed, see, seg, see, sei, sej and sel respectively.The result shows the S.aureus isolated from contamination meat able to produce different type to enterotoxins sea, sec, seg, see, sei, and sel and present the sea toxin is the most prevalence type of staphylococcus enterotoxins.
