Phylogenetic analysis of enteroaggregative and diffusely adherent Escherichia coli.
The phylogenetics of the various pathotypes of diarrheagenic Escherichia coli are not completely understood. In this study, we identified several plasmid and chromosomal genes in the pathogenic enteroaggregative E. coli (EAEC) prototype strain 042 and determined the prevalence of these loci among EAEC and diffusely adherent E. coli strains. The distribution of these genes is analyzed within an ...
متن کاملDiffusely adherent Escherichia coli as a cause of acute diarrhea in young children in Northeast Brazil: a case-control study.
In a prospective study carried out in two urban centers in northeastern Brazil, 195 HEp-2-adherent Escherichia coli strains were isolated; 110 were identified as the only pathogen in stools of children with diarrhea, and 85 were from controls. Enteropathogenic E. coli isolates were identified in 21 children with diarrhea (8.9%) and 7 children without diarrhea (3.0%), and they were significantly...
متن کاملHep-2–Adherent Escherichia coli Strains Associated with Acute Infantile Diarrhea, São Paulo, Brazil
In this paired case-control study of infants with diarrhea in São Paulo, we examined the association between HEp-2-adherent Escherichia coli strains and diarrhea. We tested isolates from stool specimens of infants with diarrhea and matched controls in an HEp-2 cell adherence assay; we then hybridized isolates with DNA probes and identified enteropathogenic E. coli (EPEC), enteroaggregative E. c...
متن کاملHeterogeneity among strains of diffusely adherent Escherichia coli isolated in Brazil.
One hundred twelve diffusely adherent Escherichia coli strains isolated from children in a case control study were evaluated for virulence-associated characteristics, serotyping, antibiotic resistance, and plasmid profiles. Half of the strains hybridized with the probes for icuA (aerobactin) and fimH (type 1 pili); daaE (F1845 fimbriae), afa (afimbrial Dr adhesin), agg-3A (aggregative adhesion ...
متن کاملComparative genomics of Crohn's disease-associated adherent-invasive Escherichia coli.
OBJECTIVE Adherent-invasive Escherichia coli (AIEC) are a leading candidate bacterial trigger for Crohn's disease (CD). The AIEC pathovar is defined by in vitro cell-line assays examining specific bacteria/cell interactions. No molecular marker exists for their identification. Our aim was to identify a molecular property common to the AIEC phenotype. DESIGN 41 B2 phylogroup E. coli strains we...
