Background: Enteroaggregative E. coli (EAEC), after enterotoxigenic E. coli (ETEC) is the leading cause of traveler's diarrhea in developing and developed countries. According to importance of chronic diarrhea, especially in children, and inappropriate traditional methods, and insufficient informations about ferequency of EAEC, molecular techniques can be very helpful. In the current study, EA...
background: diarrhea, caused by enteroaggregative escherichia coli (eaec), is an important cause of illness and death. numerous virulent factors have been described in eaec. however, their prevalence was highly variable among eaecs of distinct geographic locations. studies have shown that dispersin (antiaggregation protein, aap) is one of the important and abundant virulent factors in eaec. in ...
AIM The aim of this study was to investigate the frequency of betalactamase producing EAEC isolates among young children with diarrhea in Zanjan, Iran. BACKGROUND Entero aggregative Escherichia coli (EAEC) is an emerging enteric pathogen associated with acute and persistent diarrhea and the evolution and spread of acquired extended spectrum betalactamases (ESBLs) among these strains has becom...
The so far highest number of life-threatening hemolytic uremic syndrome was associated with a food-borne outbreak in 2011 in Germany which was caused by an enterohemorrhagic Escherichia coli (EHEC) of the rare serotype O104:H4. Most importantly, the outbreak strain harbored genes characteristic of both EHEC and enteroaggregative E. coli (EAEC). Such strains have been described seldom but due to...
The outbreak of diarrhoea and haemolytic uraemic syndrome that occurred in Germany in 2011 was caused by a Shiga toxin-producing enteroaggregative Escherichia coli (EAEC) strain. The strain was classified as EAEC owing to the presence of a plasmid (pAA) that mediates a characteristic pattern of aggregative adherence on cultured cells, the defining feature of EAEC that has classically been assoc...
Enteroaggregative Escherichia coli (EAEC) bacteria are exceptional colonizers that are associated with diarrhea. The genome of EAEC strain 042, a diarrheal pathogen validated in a human challenge study, encodes multiple colonization factors. Notable among them are aggregative adherence fimbriae (AAF/II) and a secreted antiaggregation protein (Aap). Deletion of aap is known to increase adherence...
Enteroaggregative Escherichia coli (EAEC) are quite heterogeneous category of an emerging enteric pathogen associated with cases of acute or persistent diarrhea worldwide in children and adults, and over the past decade has received increasing attention as a cause of watery diarrhea, which is often persistent. EAEC infection is an important cause of diarrhea in outbreak and non-outbreak setting...
The impact of enteroaggregative E. coli (EAEC) infection on childhood malnutrition and inflammation has been suggested, regardless of diarrhea. We investigated whether EAEC and its virulence-related genes (VRGs) are associated with malnutrition in a case-control study. Children aged 6-24 months from Brazil were enrolled as malnourished if weight-for-age Z-score (WAZ) ≤ -2 and nourished if WAZ >...
BACKGROUND Enteroaggregative Escherichia coli (EAEC) are a heterogeneous category of emerging pathogens associated with acute and persistent diarrhea. METHODS We performed a case-control study to evaluate the association of EAEC strains and their virulence markers with infantile diarrhea in Brasilia, Brazil. RESULTS Of the EAEC markers that were tested, only EAEC heat-stable toxin (EAST1), ...
Enteroaggregative Escherichia coli (EAEC) are an increasingly important cause of diarrhoea. E. coli belonging to this category cause watery diarrhoea, which is often persistent and can be inflammatory. EAEC have been implicated in sporadic diarrhoea in children and adults, in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide. EAEC are ...
