Background: Staphylococcus aureus is a gram positive coccus which is able to cause different kinds of infection in certain condition. The function of this bacteria is to provide the conditions for the invasion of it to the host with the secretion of different sorts of toxins such as Staphylococcus aureus enterotoxin, including important virulence factors that super antigens are all factors dige...

Abstract Background and Objective: The main cause of spreading staphylococcal infections among patients is the healthy carriers working in hospitals. With the secretion of different sorts of toxins such as entrotoxin, this bacteria can provide the conditions for attacking on the host.

  Background and purpose: Staphylococcus aureus (S. aureus) produces various toxins. One of the most important toxins is enterotoxin. Enterotoxin A and B play a major role in food poisoning. This research was conducted to determine the enterotoxin A and B genes in S. aureus strains. Materials and methods: In this study, 223 specimens were collected from the skin and nose of patients, medical ...

Background and purpose: Staphylococcus aureus is one of the most common causes of foodborne diseases. Enterotoxin produced by the bacterium is one of the very important virulence factors, and pyrogenic toxin super antigens (PTSAgs) that have profound effects on their hosts. This study aimed at evaluating the prevalence of S.aureus strains in different foods, examining their antimicrobial suscep...
