Enteroinvasive Escherichia coli (EIEC) outbreaks are uncommon in Europe. In June 2014, two EIEC outbreaks occurred in Nottingham, UK, within 2 days; outbreak A was linked to a takeaway restaurant and outbreak B to a wedding party. We conducted 2 analytical studies: a case-control study for outbreak A and a cohort study for outbreak B. We tested microbiological and environmental samples, includi...

Enteroinvasive Escherichia coli (EIEC) causes dysentery; however, it is less widely reported than other etiological agents in studies of diarrhea worldwide. Between August 2003 and July 2005, stool samples were collected in case-control studies in 22 rural communities in northwestern Ecuador. Infection was assessed by PCR specific for LT and STa genes of enterotoxigenic E. coli (ETEC), the bfp ...

Background: The colonic epithelium maintains a life long reciprocally beneficial interaction with the colonic microbiota. Disruption is associated with mucosal injury. Aims: We hypothesised that probiotics may limit epithelial damage induced by enteroinvasive pathogens, and promote restitution. Methods: Human intestinal epithelial cell lines (HT29/cl.19A and Caco-2) were exposed to enteroinvasi...

BACKGROUND The colonic epithelium maintains a life long reciprocally beneficial interaction with the colonic microbiota. Disruption is associated with mucosal injury. AIMS We hypothesised that probiotics may limit epithelial damage induced by enteroinvasive pathogens, and promote restitution.

In this study, polymorphism in ipa genes was found in five out of nine EIEC serotypes studied. When SalI and HindII were used in RFLP-PCR assays many EIEC serotypes showed polymorphism in ipaB and ipaD. On the other hand, no polymorphism was observed in ipaA and ipaC in these strains. The polymorphism present in EIEC strains is serotype-dependent, since restriction patterns were conserved among...

Enteroinvasive E. coli (EIEC), like Shigella, is the etiological agent of bacillary dysentery, a particularly severe syndrome in children in developing countries. All EIEC strains share with Shigella the inability to synthesize lysine decarboxylase (the LDC phenotype). The lack of this function is considered a pathoadaptive mutation whose emergence was necessary to obtain the full expression of...

conclusions by studying the profiles of virulence genes and mlva, it can be concluded that eiec isolates do not have high heterogeneity and are derived from a limited number of clones. background enteroinvasive escherichia coli (eiec) isolates cause dysentery in humans. several virulence factors associated with eiec pathogenesis have been characterized. multilocus variable-number tandem-repeat ...

We report here the draft genome sequences of enteroinvasive Escherichia coli (EIEC) O124:H30 strain M4163 isolated from imported French cheese and EIEC O143:H26 strain 4608-58. The assembled data determined that both strains contain multiple copies of the ipaH gene, as well as the pINV A form of the invasion plasmid.

BACKGROUND AND OBJECTIVES Enteroinvasive Escherichia coli (EIEC) is one the cause of acute diarrhea and bacillary dysentery in developing countries. Routine diagnostic microbiology tests are not capable to distinguish EIEC from other pathogenic or non-pathogenic E. coli. PCR, targeting ipaH, virF, virB and other virulence genes, is a diagnostic method for detecting E. coli pathotypes. Using PCR...

Among the intestinal pathogenic Escherichia coli, enteroinvasive E. coli (EIEC) are a group of intracellular pathogens able to enter epithelial cells of colon, multiplicate within them, and move between adjacent cells with a mechanism similar to Shigella, the ethiological agent of bacillary dysentery. Despite EIEC belong to the same pathotype of Shigella, they neither have the full set of trait...
