Phenotypic and Genotypic Characterization of Enterotoxic Staphylococcus aureus Isolated from Different Sources with Reference to Antimicrobial Resistance

As milk and meat products are subjected to contamination with a lot of microorganisms from different sources either during production, manufacturing, or handling especially with S. aureus which find inmilk and meat products a good media for growth, multiplication andproduction of toxins so that it becomes one source of food poisoningto man.Staphylococcus aureus is a ubiquitous commensal bacterium onhuman skins and anterior nares, but frequently causes severeinfections in humans. Rapid and direct identification of S. a ureus iscrucial for proper management of patients with skin infections,abscesses, septicaemiaibacteraemia, gastroenteritis, endocarditis, toxicshock syndrome and certain food intoxications. The purpose of this study was to evaluate phenotypic andgenotypic characterization of enterotoxic Staphylococcus aureusisolated from different sources with reference to antimicrobialresistance.One hundred and twenty six samples of human and animal wereincluded in this study, as: Sixty five samples of mastitic cow milk, and23 meat products (9 burger, 7 minced meats, and 7 sausages).Thirty eight samples of human including 12 urine, 8 sputum, 7C.S.F.,4 pericardial fluids and 7 pus.
