15 Porcine enterotoxigenic Escherichia coli (ETEC) continue to result in major morbidity 16 and mortality to the swine industry via post-weaning diarrhea. The key virulence 17 factors of these strains, their serotypes, and their fimbrial components have been 18 well studied. However, most studies to date have focused on plasmid-encoded traits 19 related to colonization and toxin production, and...

The bacterial pathogens enterotoxigenic Escherichia coli (ETEC) and Vibrio cholerae are major causes of diarrhea. ETEC causes diarrhea by production of the heat-labile toxin (LT) and heat-stable toxins (STh and STp), while V. cholerae produces cholera toxin (CT). In this study, we determined the occurrence and bacterial doses of the two pathogens and their respective toxin expression levels dir...

Enterotoxigenic Escherichia coli (ETEC) is capable of invading epithelial cell lines derived from the human colon and ileocecum. Two separate loci (tia and tib) that direct noninvasive E. coli HB101 to adhere to and invade intestinal epithelial cells have previously been cosmid cloned from ETEC H10407. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of cellular fractions from...

BACKGROUND Enterotoxigenic Escherichia coli (ETEC) are common causes of diarrheal morbidity and mortality in developing countries for which there is currently no vaccine. Heterogeneity in classical ETEC antigens known as colonization factors (CFs) and poor efficacy of toxoid-based approaches to date have impeded development of a broadly protective ETEC vaccine, prompting searches for novel mole...

Enterotoxigenic Escherichia coli (ETEC) is a major cause of childhood diarrhea. The present study sought to determine the prevalence and distribution of toxin types, colonization factors (CFs), and antimicrobial susceptibility of ETEC strains isolated from Peruvian children. We analyzed ETEC strains isolated from Peruvian children between 2 and 24 months of age in a passive surveillance study. ...

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...

This study assesses the importance of enterotoxigenic Escherichia coli (ETEC) as a diarrhoeal agent in developing countries. Odds ratios were calculated for incurring ETEC-associated diarrhoea based on data reported between 1970 and 1999. Carriage of ETEC was associated with diarrhoea in children aged less than five years, except for hospitalized infants aged 0-11 month(s) and children aged 1-4...

OBJECTIVES Enterotoxigenic Escherichia coli (ETEC) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. IgY technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. The purpose of this study was to produce specific antibody by egg yolk antibody (IgY) t...

the aim of this study was to determine the frequency of enterotoxigenic and enteroaggregative strains ofescherichia coli in chicken carcasses by polymerase chain reaction (pcr). in this study 63 strains of e. coliwere isolated from 110 samples of chicken carcasses during processing after chilling in the poultry slaughterhouse of shahrekord. polymerase chain reaction assays were used to detect t...
