In the course of the routine examination of strains of Staphylococcus aureus isolated from outbreaks of staphylococcal food poisoning in north-west England, we were surprised to find that most of them were penicillin resistant. Nine of 11 strains, all present in large numbers in foods that had caused clinically typical outbreaks of vomiting and diarrhoea, were penicillin resistant. None of the ...

Purified Staphylococcus aureus enterotoxins B and C(1), the causative agents of staphylococcal food poisoning, were resolved into several components by scanning isoelectric focusing in sucrose density gradients in the absence and presence of 6 M urea and 5 mM dithiothreitol. The observed heterogeneity persisted in the denaturing medium, which suggests that the primary structure of protein enter...

In April 2013, a food poisoning outbreak caused by staphylococcal enterotoxins (SEs) in ice-cream occurred in Freiburg, Germany, among the 31 participants of a christening party. Of the 13 cases, seven were hospitalized or obtained ambulatory treatment. Different types of ice-cream, which was freshly produced at the hotel where the party took place, were found to contain SE and high amounts of ...

Milk and dairy products are frequently contaminated with enterotoxigenic Staphylococcus aureus, which is often involved in staphylococcal food poisoning. The distribution of genes encoding staphylococcal enterotoxins (SE) in S. aureus isolated from bovine, goat, sheep and buffalo milk and dairy products was verified by the presence of the corresponding SE production. A total of 112 strains of S...

conclusions resistance to oxacillin and other antibiotics was high, and most of the isolates were found to be multi-drug resistance (mdr). plasmid analysis of representative s. aureus isolates also demonstrates the presence of a wide range of plasmid sizes, with no consistent relationship between plasmid profiles and resistance phenotypes. regular surveillance of hospital infections and monitor...

Staphylococci are a worldwide cause of human and animal infections including life-threatening cases of bacteraemia, wound infections, pyogenic lesions, and mastitis. Enterotoxins produced by some staphylococcal species were recognized as causative agents of staphylococcal food poisoning (SFP), being also able to interrupt human and animal immune responses. Only enterotoxins produced by Staphylo...

abstract        background and objective: staphylococcus aureus is the most common and important infectious agent. this bacterium can enter the bloodstream and cause some complications in the intensive care unit (icu).this organism can frequently be found in the nose and transmitted by the carriers. this study aimed to determine the efficiency of eradicating s. aureus from the nose of icu perso...

On August 4, 2005, 20 people who participated in the closing ceremonies of a community festival experienced nausea, vomiting, diarrhea and abdominal pain. The community where the festival took place was under the jurisdiction of the Aizu Health Center of Fukushima Prefecture. The foods that all of these patients had consumed were rice balls prepared by caterer A. Another 8 people, who did not p...
