Enteroaggregative Escherichia coli (EAEC) is an increasingly recognized pathogen associated with acute and persistent diarrhea worldwide. While EAEC strains are considered highly heterogeneous, aggregative adherence fimbriae (AAFs) are thought to play a pivotal role in pathogenicity by facilitating adherence to the intestinal mucosa. In this study, we optimized an existing multiplex PCR to targ...

Diarrheal diseases are a leading cause of mortality and morbidity especially among children in developing countries resulting in a major health care problem. Medicinal plants constitute the major component of traditional medicine practiced worldwide due to the economical viability, accessibility, and ancestral experience. Two medicinal plants (Punica granatum, Syzygium cumini) used in diarrheal...

BACKGROUND Conflicting studies exist regarding the role of enteroaggregative Escherichia coli (EAEC) as a cause of acute diarrheal illness. The objective of this meta-analysis was to determine whether identification of EAEC in stool samples is associated with acute diarrheal illness among different subpopulations, by geographic area. METHODS A comprehensive search of electronic bibliographic ...

In 2011, nearly 4,000 people in Germany were infected by Shiga toxin (Stx)-producing Escherichia coli O104:H4 with > 22% of patients developing haemolytic uraemic syndrome (HUS). Genome sequencing showed the outbreak strain to be related to enteroaggregative E. coli (EAEC), suggesting its high virulence results from EAEC-typical strong adherence and biofilm formation combined to Stx production....

In 2011, a Shiga toxin (Stx) type 2a-producing enteroaggregative E. coli (EAEC) strain of serotype O104:H4 caused a large lethal outbreak in Northern Europe. Until recently, the pathogenic mechanisms explaining the high virulence of the strain have remained unclear. Our laboratories have shown that EAEC genes encoded on the pAA virulence plasmid, particularly the AggR-regulated AAF/I fimbriae, ...

Background: Diarrheagenic Escherichia coli (DEC) is regarded as a great public health concern all around the world causing diarrhoea which can be transmitted through food chain. Aims: This study aimed to determine the contamination level and exact distribution rate of DEC in food products consumed by human. Methods: Seven hundred and t...

Diverse enteropathogen exposures associate with childhood malnutrition. To elucidate mechanistic pathways whereby enteric microbes interact during malnutrition, we used protein deficiency in mice to develop a new model of co-enteropathogen enteropathy. Focusing on common enteropathogens in malnourished children, Giardia lamblia and enteroaggregative Escherichia coli (EAEC), we provide new insig...

BACKGROUND Enteroaggregative Escherichia coli (EAEC) causes diarrhea, malnutrition and poor growth in children. Human breast milk decreases disease-causing bacteria by supplying nutrients and antimicrobial factors such as lysozyme. Goat milk with and without human lysozyme (HLZ) may improve the repair of intestinal barrier function damage induced by EAEC. This work investigates the effect of th...

Various non-spore forming bacteria, including Escherichia coli, enter a dormant-like state, the viable but non-culturable (VBNC) state, characterized by the presence of viable cells but the inability to grow on routine laboratory media. Upon resuscitation, these VBNC cells recover both culturability and pathogenicity. In 2011, a large outbreak involving more than 3000 cases of bloody diarrhoea ...
