Diarrhea continues to be a leading cause of death in children <5 years of age, and enterotoxigenic Escherichia coli (ETEC) is the most common bacterial cause of children's diarrhea. Currently, there are no available vaccines against ETEC-associated diarrhea. Whole-cell vaccine candidates have been under development but require further improvements because they provide inadequate protection and ...

Enterotoxigenic Escherichia coli (ETEC) is a common cause of profuse watery diarrhoea in the developing world, often leading to severe dehydration or death. We found only 15 population-based studies in low and medium human development index (HDI) countries from 1984 to 2005 that evaluate disease incidence. Reported incidence ranged from 39 to 4460 infections/1000 persons per year. The peak inci...

BACKGROUND Diarrhea is a prevalent pathological condition frequently associated to the colonization of the small intestine by enterotoxigenic Escherichia coli (ETEC) strains, known to be endemic in developing countries. These strains can produce two enterotoxins associated with the manifestation of clinical symptoms that can be used to detect these pathogens. Although several detection tests ha...

Gnotobiotic calves were inoculated with an O5:K4:H-, urease-positive strain of Escherichia coli isolated from a 2-day-old calf with diarrhea. The calves developed elevated temperatures and passed loose mucoid feces, with or without blood. The E. coli strain was negative for heat-stable and heat-labile enterotoxins but produced high levels of Shiga-like toxin. Bacteria attached diffusely to the ...

Enterotoxigenic Escherichia coli (ETEC) is one of the major causes of infectious diarrhea in developing countries. In order to characterize the molecular features of human ETEC isolates from Korea, we investigated the profiles of enterotoxin and colonization factor (CF) genes by polymerase chain reaction (PCR) and performed multilocus sequence typing (MLST) with a total of 291 ETEC strains. The...

Porcine Post-Weaning Diarrhea (PWD) continues to be one of the most important swine diseases worldwide. Entero toxigenic Escherichia coli (ETEC) strains are the primary cause of PWD. The key virulence factors of ETEC in PWD are bacterial fimbrial adhesins and enterotoxins. Adhesions mediate ETEC bacteria initial attachment to pig epithelial cells and subsequent colonization at pig small intesti...

A toxin from an enteropathogenic strain of Escherichia coli (E. coli H30) was purified to apparent homogeneity from cell lysates. The steps used to isolate the E. coli H30 toxin included French pressure-cell disruption of bacteria grown in iron-depleted media. Affi-Gel Blue chromatography, chromatofocusing, and anti-Shiga toxin affinity chromatography. The mobilities of the subunits of radioiod...

Background:Toxic contamination of fish may compromise food safety. Haff disease is a rare syndrome characterized by rhabdomyolysis following consumption of cooked, freshwater fish. Case Report: A healthy 42 year old female presented three hours after eating fried buffalo fish (Ictiobus cyprinellis). Her symptoms began while eating the fish, described as diffuse muscle aches followed by generali...
