Loss of Biofilm Formation in an Emerging Foodborne Pathogen Enteroaggregative Escherichia coli (EAEC) Under Acid Stress
Purpose: Enteroaggregative Escherichia coli (EAEC) is an emerging foodborne pathogen as a significant diarrheal pathogen in multiple population groups. However, the associated phenotypic changes by which EAEC bacteria survive acid conditions, as it passes through the human digestive track, is not completely understood. Materials and methods: EAEC (T8) was grown in vitro by mimicking the in vivo...
متن کاملEnteroaggregative Escherichia Coli (EAEC) in South of Iran
Introduction: The aim of the present study was to investigate the presence and the frequency of EAEC as etiologic agent of diarrhea in Shiraz. Enteroaggregative E. coli (EAEC) is increasingly recognized as a cause of often persistent diarrhoea in children and adults in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide. Materials and...

متن کاملdistribution of virulence genes, enterotoxin and biofilm formation among enteroaggregative escherichia coli (eaec) strains isolated from stools of children with diarrhea in south east iran
conclusions overall, except for pcvd432 and aggr, we detected high heterogeneity of virulence factors among eaec isolates causing diarrhea in children. one set of genes, in the combination, pic- sepa- agg4a, was associated with strong biofilm. results among the 322 e. coli isolated, 23 were identified as eaec. all eaec carried a 630-bp fragment of the plasmid (paa) encoded pcvd432 and aggr gene...
متن کاملIdentification of key proteins of cultured human intestinal cells involved in interaction with enteroaggregative Escherichia coli.
Enteroaggregative Escherichia coli (EAEC) adherence to human intestinal tissue is known to be mediated by aggregative adherence fimbriae (AAF). However, the host cell molecules involved in EAEC adherence remain uncharacterized. In the present study, four key membrane glycoproteins of cultured human intestinal epithelial cells (INT-407) were found to be involved in the interaction with the T8 st...
