Staphylococcal food poisoning (SFP) caused by enterotoxigenic staphylococci is one of the main food-borne diseases. In contrast to Staphylococcus aureus, a systematic screening for the enterotoxins has not yet been performed on the genomic level for the coagulase-positive species S. intermedius. Therefore, the enterotoxigenic potential of 281 different veterinary (canine, n = 247; equine, n = 2...

This study evaluated a direct multiplex PCR to detect food contamination with enterotoxigenic Bacillus cereus (B. cereus) in comparison with culture and multiplex gene detection using colonies. Detection of B. cereus enterotoxin genes was done on artificially contaminated and ready-toeat market foods including cooked rice, pasteurized milk and cheese. Of the 108 food samples analysed, 51(47.2 %...

Domiati cheese is the most popular type of white soft in Egypt. Staphylococcus aureus a common microorganism that can easily contaminate during processing and distribution. Enterotoxigenic S. strains produce staphylococcal enterotoxins (SE) have been involved food poisoning outbreaks worldwide. The aim present study was to examine inhibitory effect yoghourt starter culture nickel oxide nanopart...

Bacteroides fragilis constitutes about 1% of the bacterial flora in intestines of normal humans. Enterotoxigenic strains of B. fragilis have been associated with diarrheal diseases in humans and animals. The enterotoxin produced by these isolates induces fluid changes in ligated intestinal loops and an in vitro cytotoxic response in HT-29 cells. We developed a nested PCR to detect the enterotox...

Background: Intoxication by heat-resistant Staphylococcus aureus enterotoxins (SEs), particularly SEA and SEE, is one of the most common causes food poisoning in world. Objectives: This study aimed to identify enterotoxin-encoding genes (see, sed, sec, seb, sea) S. isolates from different restaurant employees. Methods: Ninety-one samples hands noses employees several restaurants Golestan Provin...

However, pigs older than approximately 8 weeks appear to be resistant to infection. Strains of ET...

Calf diarrhea due to infection by enterotoxigenic Escherichia coli was treated by administration of glycoprotein glycans derived from bovine plasma. The glycan moieties of the nonimmunoglobulin fraction of plasma mimicked the oligosaccharide moiety of intestinal receptors recognized by K99 pili. These glycoprotein glycans inhibited adhesion of E. coli K99+ ST+ to erythrocyte glycoconjugates in ...
