Persistent colonization of sheep by Escherichia coli O157:H7 and other E. coli pathotypes.
Shiga toxin-producing Escherichia coli (STEC) is an important cause of food-borne illness in humans. Ruminants appear to be more frequently colonized by STEC than are other animals, but the reason(s) for this is unknown. We compared the frequency, magnitude, duration, and transmissibility of colonization of sheep by E. coli O157:H7 to that by other pathotypes of E. coli. Young adult sheep were ...
متن کاملEscherichia coli pathotypes occupy distinct niches in the mouse intestine.
Since the first step of the infection process is colonization of the host, it is important to understand how Escherichia coli pathogens successfully colonize the intestine. We previously showed that enterohemorrhagic O157:H7 strain E. coli EDL933 colonizes a niche in the streptomycin-treated mouse intestine that is distinct from that of human commensal strains, which explains how E. coli EDL933...
متن کاملMolecular characterization of uropathogenic and diarrheagenic Escherichia coli pathotypes.
In this study diarrheagenic and uropathogenic Escherichia coli (UPEC) strains were comparatively characterized according to serotype, hemolytic activity, protein polymorphism among housekeeping enzymes, phylogenetic group and urovirulence genes. Intra-serogroup/serotype variations were observed. Hemolytic activity was detected in 100%, 93%, 67% and 39% of UPEC, EAEC, EPEC and ETEC strains, resp...
متن کاملGenetic relationship of diarrheagenic Escherichia coli pathotypes among the enteropathogenic Escherichia coli O serogroup.
The genetic relationship among the Escherichia coli pathotypes was investigated. We used random amplified polymorphic DNA (RAPD) data for constructing a dendrogram of 73 strains of diarrheagenic E. coli. A phylogenetic tree encompassing 15 serotypes from different pathotypes was constructed using multilocus sequence typing data. Phylogram clusters were used for validating RAPD data on the clona...
متن کاملDiarrheagenic Escherichia coli pathotypes frequency in Khuzestan province of Iran
BACKGROUND AND OBJECTIVES Diarrheagenic Escherichia coli (DEC) is an emerging agent among pathogens that causes diarrhea. Studies showed that diarrheagenic E. coli such as enterohaemorrhagic E. coli (EHEC), enteroaggregative E. coli (EAEC), enteropathogenic E. coli (EPEC), enteroinvasive E. coli (EIEC), enterotoxigenic E. coli (ETEC), diffusely adhering E. coli (DAEC) and shiga toxin producing ...
