Invasive properties, adhesion patterns and phylogroup profiles among Escherichia coli strains isolated from children with inflammatory bowel disease.

Background: A great deal of evidence indicates a link between Escherichia coli (E. coli) and Crohn's disease in adult patients, but there is lack of information on the association of these bacilli with inflammatory bowel disease (IBD) among children.

Objectives: The study was carried out to determine the distribution of phylogenetic group, the adherence patterns and invasive properties of E.

Association of untypeable enteropathogenic Escherichia coli (EPEC) strains with persistent diarrhea in children from the region of lower Silesia in Poland.

Enteropathogenic Escherichia coli strains (EPEC) carrying the eae gene encoding intimin are divided into typical strains producing bundle forming pili, encoded by the bfpA gene, and atypical strains lacking the gene. In the study typical and atypical EPEC that did not agglutinated with EPEC polyvalent antisera but carrying virulence factors characteristic to other pathogenic E. coli i.

Characterization of genes associated with internalization of enteroaggregative Escherichia coli.

On animal models enteroaggregative Escherichia coli (EAEC) can cause mild, but significant mucosal damage, suggesting the invasive capability of these strains. In the study we investigated the ability of typical, aggR-positive and atypical, aggR-negative EAEC isolates to enter intestinal epithelial Int407 cells in relation to the distribution of genes encoding the putative invasins described among pathogenic E. coli categories.
