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 ...

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...

Monoclonal antibodies directed against the a determinant of K88 pili from porcine enterotoxigenic Escherichia coli which react with all three K88 variants have been produced. These antibodies have been used for diagnosis of porcine enterotoxigenic E. coli in a direct enzyme-linked immunosorbent assay with sensitivity to 50 ng of pilus protein per ml.

Mortality and morbidity associated with Escherichia coli cause economic losses to the swine industry. Enterotoxigenic strains of E. coli affecting nursery-age pigs have become more difficult to treat because of increased antibiotic resistance, and alternatives to antibiotics are currently being sought. Our laboratory developed a defined culture of commensal bacteria of porcine gastrointestinal ...

Enterotoxigenic Escherichia coli (ETEC) is a water and food-borne pathogen that infects the small intestine of the human gut and causes diarrhoea. Enterotoxigenic E. coli adheres to the epithelium by means of colonization factors and secretes two enterotoxins, the heat labile toxin and/or the heat stable toxin that both deregulate ion channels and cause secretory diarrhoea. Enterotoxigenic E. c...

background: introduction: enterotoxigenic escherichia coli (etec) is the most important bacterial cause of watery  travelers' diarrhea  in  developing countries. watery diarrhea is can cause serious life-threatening dehydration. etec was caused diarrhea by the secretion of two heat-labile enterotoxins (lts) and the heat-stable enterotoxins (sts) which increase intestinal secretion. routine labo...
