Abstract:

The aim of the present case control study was to investigate the prevalence of atypical enteropathogenic Escherichia coli (EPEC) and its possible role in causing diarrhoea among children < 5 years of age in Norway. Stool specimens received in the laboratory from children with suspected gastroenteritis (n = 251) were, in addition to routine testing, analysed for the presence of EPEC by PCR of the eae, bfpA and stx genes. Specimens from healthy children (n = 210) recruited from Maternal and Child Health Centres were analysed for EPEC only. EPEC isolates (eae +, stx −) were classified as typic

Abstract:

Diarrheal disease is still a major public health concern, as it is still considered an important cause of death in children under five years of age. A few decades ago, the detection of enteropathogenic E. coli was made by detecting the O, H, and K antigens, mostly by agglutination. The recent protocols recommend the molecular methods for diagnosing EPEC, as they can distinguish between typical and atypical EPEC by identifying the presence/absence of specific virulence factors. EPEC are defined as diarrheagenic strains of E. coli that can produce attaching and effacing lesions on the intestinal

ABSTRACTAtypical enteropathogenicEscherichia coli(aEPEC) has emerged as a significant cause of pediatric diarrhea worldwide; however, information regarding its adherence mechanisms to the human gut mucosa is lacking. In this study, we investigated the prevalence of several (fimA,ecpA,csgA,elfA, andhcpA) fimbrial genes in 71 aEPEC strains isolated from children with diarrhea (54 strains) and healthy individuals (17 strains) in Brazil and Australia by PCR. These genes are associated with adhesion and/or biofilm formation of pathogenic and commensalE. coli. Here, the most prevalent fimbrial genes

ABSTRACT Atypical enteropathogenic Escherichia coli (aEPEC) and Shiga toxin-producing E. coli (STEC) were examined to determine the prevalence and sequence of espP, which encodes a serine protease. These analyses indicated shared espP sequence types between the two E. coli pathotypes and thus provide further insights into the evolution of aEPEC and STEC.

The genetic diversity of 41 typical and atypical enteropathogenic Escherichia coli (EPEC) strains of the serogroup O55 was analyzed by using the random amplified polymorphic DNA (RAPD) method. All typical EPEC O55 strains were grouped in two clusters (A and C) and belonged to the serotype O55:H6, while cluster B included all atypical strains, which were of the serotype O55:H7. The three groups also included non-motile strains. RAPD may be a useful method for epidemiological studies on E. coli O55 infection.

Diarrheagenic Escherichia coli is the major bacterial etiological agent of severe diarrhea and a major concern of public health.

One of the possible combinations is with extraintestinal E. coli (ExPEC), a leading cause of urinary tract infection, often lethal after entering the bloodstream and atypical enteropathogenic E. coli (aEPEC), responsible for de

Abstract:

ABSTRACTDiarrhea is responsible for the death of approximately 900,000 children per year worldwide. In children, typical enteropathogenicEscherichia coli(EPEC) is a common cause of diarrhea and is associated with a higher hazard of death. Typical EPEC infection is rare in animals and poorly reproduced in experimental animal models. In contrast, atypical EPEC (aEPEC) infection is common in both children and animals, but its role in diarrhea is uncertain. Mortality in kittens is often attributed to diarrhea, and we previously identified enteroadherent EPEC in the intestines of deceased kittens.

Abstract:

ABSTRACT Atypical enteropathogenic Escherichia coli (aEPEC) is an emerging pathogen that has been implicated in outbreaks of diarrhea worldwide. The objective of this study was to investigate the occurrence of aEPEC in retail foods at markets in the People's Republic of China and to characterize the isolates for virulence genes, intimin gene (eae) subtypes, multilocus sequence types (STs), and antimicrobial susceptibility. From May 2014 to April 2015, 1,200 food samples were collected from retail markets in China, and 41 aEPEC isolates were detected in 2.75% (33 of 1,200) of the food samples.

Abstract:

The expression of flagella correlates with different aspects of bacterial pathogenicity, ranging from adherence to host cells to activation of inflammatory responses by the innate immune system. In the present study, we investigated the role of flagella in the adherence of an atypical enteropathogenicEscherichia coli(aEPEC) strain (serotype O51:H40) to human enterocytes. Accordingly, isogenic mutants deficient in flagellin (FliC), the flagellar structural subunit; the flagellar cap protein (FliD); or the MotAB proteins, involved in the control of flagellar motion, were generated and tested for

The study reports the prevalence, characterisation, and molecular epidemiology of EPEC from piglets in northeastern India.Material and MethodsA total of 457 faecal samples were collected, from which 1,286 E. coli strains were isolated and screened by PCR. The resultant EPEC strains were serotyped and phenotypically characterised for resistance against 15 antimicrobials. Also, the phylogenetic sequence was analysed for 11 selected str

The use of probiotic bacteria to prevent diarrhea is gaining increasing interest. The probioticE. colistrain Nissle 1917 (EcN) is known to be effective in the treatment of several gastrointestinal disorders. While bothin vitroandin vivostudies have described strong inhibitory effects of EcN on enteropathogenic bacteria, including pathogenicE. coli, the underlying molecular mechanisms remain largely unknown.

ABSTRACT Background: Diarrheal diseases are a major cause of morbidity and mortality in resource-limited countries. Among the bacterial pathogens, diarrheagenic E. coli (DEC) are most frequently implicated in cases of epidemic and endemic diarrhea worldwide. The objective of this study was to determine the prevalence of DEC in stool specimens from patients with acute diarrhea using polymerase chain reaction (PCR). Materials and Methods: Escherichia coli stool samples were collected from 115 hospitalized children and adults with acute diarrhea in Mangalore, a coastal city, in southern India. PC

Abstract:

ABSTRACT 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 the existence of conserved Tir- and TccP-independent mechanisms of A/E lesion formation in a range of hosts and reinforce the zoonotic potential of EPEC in cattle.

Abstract:

ABSTRACT Enteropathogenic Escherichia coli (EPEC) is an important causal agent of diarrheal illness throughout the world. Nevertheless, researchers have only recently begun to explore its capacity to form biofilms. Strain O55:H7 (DMS9) is a clinical isolate belonging to the atypical EPEC (aEPEC) group, which displays a high degree of genetic relatedness to enterohemorrhagic E. coli. Strain DMS9 formed a robust biofilm on an abiotic surface at 26Ã¯Â¿Â½C, but not at 37Ã¯Â¿Â½C. It also formed a dense pellicle at the air-liquid interface and developed a red, rough, and dry (RDAR) morphotype on Con

Abstract:

Historically, enteropathogenic Escherichia coli (EPEC) are a well-known cause of outbreaks of infantile diarrhoea associated with morbidity and mortality in England. The aim of this study was to provide an update on the microbiology and epidemiology of strains of EPEC in England between 2010 and 2012. A wide range of E. coli serogroups were identified, with the most common being E. coli O145, O49 and O157. Few isolates (9 %) had additional virulence factors (specifically bfp, vtx2f and espT genes) and the majority were classified as atypical EPEC. The majority of cases (86 %) were among childr
