Diarrhea is an important cause of morbidity and mortality amongst infants of low socio-economic levels in developing countries and in travelers who visit such areas. Enterotoxigenic E. coli strains express two sets of virulence-associated factors: enterotoxins (heat-stable toxins or heat-labile toxins) and colonization factors. Studies have shown that breast-feeding protects infants against inf...

Food poisoning and non-food poisoning illnesses due to C. perfringens (by enterotoxin production) have been associated to chromosomal or plasmidic location of the cpe gene, respectively. Clostridial pathogenicity has been correlated to protease and azoreductase production. The aim of this work was: i) to assess the sanitary-hygienic quality of dehydrated soups (100 samples) consumed in San Luis...

Enterotoxigenic Bacteroides fragilis was isolated from stool specimens of 8 of 44 diarrheic individuals (ages, 4 months to 69 years). The individuals had watery diarrhea and intestinal cramping; and infants had hyperthermia, vomiting, and blood in the stools. No recognized enteric pathogens were detected in seven of the eight diarrheic individuals positive for enterotoxigenic B. fragilis. The b...

We identified enterotoxigenic Bacteroides fragilis in stool specimens of patients with inflammatory bowel disease and other gastrointestinal disorders. The organism was detected in 11 (13.2%) of 83 patients with inflammatory bowel disease. Of 57 patients with active disease, 19.3% were toxin positive; none of those with inactive disease had specimens positive for enterotoxigenic Bacteroides fra...

Pigs infected with hemolytic F4(+) strains of enterotoxigenic Escherichia coli often develop septicemia secondary to intestinal infection. We tested the hypothesis that inactivation of hemolysin would reduce the ability of F4(+) enterotoxigenic E. coli to cause septicemia in swine following oral inoculation. Inactivation of the hemolysin structural gene (hlyA) did not decrease the incidence of ...

the role of enterotoxigenic e.coli as a causative agent in diarrheal disease was studied among 100 cases of infant and children 0-2 years of age. routine bacteriological methods were used for identification enteropathogenic e.coli, salmonella, shigella and vibrio cholera. the ability of e.coli strains to produce toxin was assayed in animal models (rebbit-ileal loop and suckling mice) and in tis...

In this study, the enterotoxigenic potential of Staphylococcus strains (n = 574) isolated from raw milk samples (n = 140) was determined for their capacity to produce staphylococcal enterotoxins. In addition, the relationship between the presence of enterotoxins, coagulase, and thermonuclease (Tnase) was assessed. The results showed that 19% of Staphylococcus was enterotoxigenic, being able to ...

A novel agarolytic gammaproteobacterium, ITALIC! Paraglaciecolasp. S66, was isolated from marine samples of eelgrass ( ITALIC! Zosterasp.) and sequenced. The draft genome contains a large number of enzyme-encoding genes with predicted function against several complex polysaccharides found in the cell walls of algae.

Enterotoxigenic Escherichia coli is a multidrug-resistant bacterium that is well known for its ability to cause diarrhea in humans. Bacteriophages may be used to treat clinical cases involving bacterial dysentery. Here, we present the complete genome sequence of an enterotoxigenic E. coli phage, Pollock, an N4-like podophage.

Foodborne diseases occur worldwide, including those acquired through the consumption of contaminated meat. This study aimed to investigate the prevalence of enterotoxigenic Staphylococcus aureus, Salmonella and Escherichia coli pathotypes in different meat types. Forty meat samples fresh (n=35) and frozen (n=5) were purchased from local markets in Jenin district, Palestine. Multiplex PCR was us...
