The role of enteropathogenic Escherichia coli (EPEC) was evaluated in a group of children with endemic diarrhea admitted to Dhaka Shishu Hospital in Dacca, Bangladesh. EPEC was detected in fecal samples of 23% of 104 cases and 8% of 74 concurrent control children. The most commonly isolated EPEC strains were serogroups O20a, O20c:K61; O20a, O20b:K84; O26:K60; and O18a, O18c:K77. Except for O26:...

AIM We intended to find out the diversity of EPEC isolates among asymptomatic or diarrheal children in Iran using ribotyping. BACKGROUND Enteropathogenic Escherichia coli (EPEC) is responsible for gastroenteritis especially in young children. PATIENTS AND METHODS A total of 39 EPEC collected strains were serotyped and the presence of virulence genes as well as EAF plasmid among the strains ...

Nucleolin is a prominent nucleolar protein that is mobilized into the cytoplasm during infection by enteropathogenic Escherichia coli (EPEC). Nucleolin also exists at low levels at the cell surface of eukaryotic cells and here we show that upon infection of an intestinal cell model, EPEC recruits and subsequently sequesters cell-surface EGFP-nucleolin into extracellularly located bacterial micr...

OBJECTIVES To determine the aetiology, epidemiology and sanitary factors of carriage of enteropathogenic Escherichia coli (EPEC) and Shiga-toxin producing E. coli (STEC) in food-handlers working in tourist hotels in three popular tourist destinations in Kenya. DESIGN Cross sectional laboratory based study. SETTING Three tourist destinations of Nairobi, Malindi and Diani in Kenya. SUBJECTS...

Enteropathogenic Escherichia coli (EPEC) can be found in healthy and diarrheic cattle; however, little is known about the role of attaching and effacing (A/E) lesion formation in colonization of bovine intestinal mucosa by such strains. We show that typical and atypical EPEC induce A/E lesions on calf intestinal explants independently of Tir tyrosine phosphorylation and TccP. Our data support t...

Enteropathogenic Escherichia coli (EPEC) infection of the human small intestine induces severe watery diarrhoea linked to a rather weak inflammatory response despite EPEC's in vivo capacity to disrupt epithelial barrier function. Here, we demonstrate that EPEC flagellin triggers the secretion of the pro-inflammatory cytokine, interleukin (IL)-8, from small (Caco-2) and large (T84) intestinal ep...

Enteropathogenic Escherichia coli (EPEC), including diffusely adhering atypical E. coli, strains use a type III secretion system to deliver effector proteins into the membrane and cytoplasm of infected cells. The E. coli secreted proteins A, B, and D (EspA, EspB, and EspD) are required for the formation of the characteristic attaching and effacing (A/E) lesions. EspB and EspD are thought to for...

A key strategy in microbial pathogenesis is the subversion of the first line of cellular immune defences presented by professional phagocytes. Enteropathogenic and enterohaemorrhagic Escherichia coli (EPEC and EHEC respectively) remain extracellular while colonizing the gut mucosa by attaching and effacing mechanism. EPEC use the type three secretion system effector protein EspF to prevent thei...
