Genotypic characterization of enterotoxigenic Escherichia coli strains causing traveler's diarrhea.
This study aims to characterize the presence of virulence factors of enterotoxigenic Escherichia coli (ETEC) causing traveler's diarrhea. Among 52 ETEC isolates, the most common toxin type was STh, and the most frequent colonization factors (CFs) were CS21, CS6, and CS3. On the other hand, the nonclassical virulence factors EAST1 and EatA were frequently present.
متن کاملComplete Genome Sequences of Two Porcine Enterotoxigenic Escherichia coli Strains
Enterotoxigenic Escherichia coli (ETEC) is one of the main causes of illness and death in neonatal and recently weaned pigs. Here, we sequenced the genomes of two ETEC strains that were previously used as inactivated vaccines in China.
متن کاملEnterotoxigenic Escherichia coli strains belonging to a new serogroup, Escherichia coli O166.
Thirty-two strains of Escherichia coli belonging to a new O group, O166, were examined. Twenty-one strains had the flagella antigen H27, five had the H15 antigen, five had the H7 antigen, and one was nonmotile. All the H27 strains and the nonmotile strain produced heat-stable enterotoxin but not heat-labile enterotoxin. All the H7 strains produced heat-labile enterotoxin but not heat-stable ent...
متن کاملEvaluation of Experimental Conditions for Quantification of Lt Produced by Human Derived Enterotoxigenic Escherichia Coli Strains
The heat-labile toxin (LT) is a key virulence-associated factor associated with the non-invasive secretory diarrhea caused by enterotoxigenic Escherichia coli (ETEC) strains either in humans or domestic animals. Several LT detection methods have been reported but quantification of the toxin produced by wild-type ETEC strains is usually performed by the GM1 ganglyoside enzyme-linked immunosorben...
متن کاملIsolation of enterotoxigenic and enteroaggregative straines of Escherichia coli from chicken carcasses by PCR
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...
