BACKGROUND AND OBJECTIVES Diarrheagenic Escherichia coli (DEC) is an emerging agent among pathogens that causes diarrhea. Studies showed that diarrheagenic E. coli such as enterohaemorrhagic E. coli (EHEC), enteroaggregative E. coli (EAEC), enteropathogenic E. coli (EPEC), enteroinvasive E. coli (EIEC), enterotoxigenic E. coli (ETEC), diffusely adhering E. coli (DAEC) and shiga toxin producing ...

background and objectives: diarrheagenic escherichia coli (dec) is an emerging agent among pathogens that causes diarrhea. studies showed that diarrheagenic e. coli such as enterohaemorrhagic e. coli (ehec), enteroaggregative e. coli (eaec), enteropathogenic e. coli (epec), enteroinvasive e. coli (eiec), enterotoxigenic e. coli (etec), diffusely adhering e. coli (daec) and shiga toxin producing...

Diarrheagenic Escherichia coli (DEC) strains are a main cause of gastrointestinal disease in developing countries. In this study we report the epidemiologic surveillance in a 4-year period (January 2011 to December 2014) of DEC strains causing acute diarrhea throughout the Sinaloa State, Mexico. DEC strains were isolated from outpatients of all ages with acute diarrhea (N = 1,037). Specific DEC...

This study compared the proteomic profile of outer membrane proteins (OMPs) from one strain of atypical enteropathogenic Escherichia coli (aEPEC) and one of typical EPEC (tEPEC). The OMPs fractions were obtained using sarcosine extraction, and analyzed by one- and two-dimensional gel electrophoresis (1DE and 2DE, respectively). The 1DE OMPs analysis of typical and atypical EPEC evidenced simila...

UNLABELLED Enteropathogenic Escherichia coli (EPEC) has the ability to antagonize host apoptosis during infection through promotion and inhibition of effectors injected by the type III secretion system (T3SS), but the total number of these effectors and the overall functional relationships between these effectors during infection are poorly understood. EspC produced by EPEC cleaves fodrin, paxi...

Enteropathogenic Escherichia coli (EPEC) strains are a significant cause of acute and persistent diarrhea in humans, which are transmitted primarily through consumption of contaminated foods. The present study was performed for the identification of EPEC strains from contaminated meat by a PCR technique. A panel of reference E. coli strains purchased from NBIMCC; Sofia, Bulgaria was used for th...

Enteropathogenic Escherichia coli is a foodborne pathogen that produces potentially fatal infant diarrhea, noticeably in developing countries. The aim of this study was to detect EPEC contamination by PCR at different stages of the chicken slaughtering process. We collected swabs from chicken cloacae and washed carcasses (external and visceral cavity) during the slaughtering process in 3 sampli...

Escherichia coli strains that cause nonbloody diarrhea in infants are known to present three distinct patterns of adherence to epithelial cells, namely, localized (LA), diffuse (DA), and aggregative (AA) adherence. Strains with LA (typical Enteropathogenic Escherichia coli [EPEC]) are well recognized as a cause of secretory diarrhea, but the role of strains with DA (DAEC) is controversial, and ...

Typical and atypical enteropathogenic Escherichia coli (EPEC) are considered important bacterial causes of diarrhoea. Considering the repertoire of virulence genes, atypical EPEC (aEPEC) is a heterogeneous group, harbouring genes that are found in other diarrheagenic E. coli pathotypes, such as those encoding haemolysins. Haemolysins are cytolytic toxins that lyse host cells disrupting the func...
