Classically, pathogenic strains of Escherichia coli were thought to cause intestinal infections (II) or extraintestinal infections (IEI). However, several recent reports have demonstrated the occurrence of E. coli strains causing II and IEI in the same patient. Typical enteroaggregative E. coli (EAEC), one of the intestinal pathogenic E. coli pathotypes, is characterized by harboring a v…
Escherichia coli are characterized by harboring both commensal and / or symbiotic strains, as well as strains that are pathogenic to the intestinal and extraintestinal sites of humans and warm-blooded animals. This plurality of behavior is due, on the one hand, to the fact that most of its virulence determinants are encoded in mobile genetic elements and, on the other hand, the extreme pe…
Some adapted clones of Escherichia coli carry genes that encode properties that allow them to colonize different host sites, favoring the establishment of intestinal or extraintestinal infections. Intestinal infections are caused by different diarrheogenic E. coli (DEC) pathotypes, while the extraintestinal infections are caused by strains of extraintestinal pathogenic E. coli (ExPEC). Ex…
Enteropathogenic Escherichia coli (EPEC) produce characteristic intestinal lesions (attaching/effacing lesions, A/E), being identified by the production of the localized adherence (LA+) pattern in HeLa cells. LA+ EPEC strains of the O119:H6 serotype constituted, for many decades, one of the most frequent childhood diarrheal agents in our environment. Curiously, we have identified O119:H6 …

Escherichia coli is a commensal bacterium present in the human intestinal microbiota. However, some strains have evolved by acquiring virulence genes that have turned them into pathogenic strains that can cause diarrhea and various types of extraintestinal infections. Six diarrheagenic pathotypes of E. coli have been described, which are transmitted through person-to-person contact, the…
Pathogenic strains of Escherichia coli were considered to have the ability to cause only intestinal (II) or extraintestinal (IEI) infections. However, recent studies have reported the occurrence of strains of E. coli leading to both types of infections in the same patient. The frequent isolation of enteroaggregative E. coli (EAEC) from sites of extraintestinal infections has raised the qu…
Infection of the intestinal epithelium by certain enteropathogens results in a modification in the expression of genes encoding pro-inflammatory cytokines and the production of mucins. Our group demonstrated that some strains of atypical enteropathogenic Escherichia coli (aEPEC) significantly increase mucus production when inoculated into ligated rabbit ileal loops in vivo. In the same st…
Escherichia coli is a globally distributed bacterium that colonizes the gut. E. coli strains can be divided into three groups: commensals, which are harmless to the host; diarrheagenic (diarrheagenic E. coli-DEC), which cause intestinal diseases; and those which cause extraintestinal infections (extraintestinal pathogenic E. coli-ExPEC). ExPEC strains are classified according to the site …

The isolation of enteroaggregative Escherichia coli (EAEC) from extraintestinal sites has been increasingly frequent. This fact has raised questions about the relevance of the pAA plasmid in extraintestinal infections, given that it is responsible for coding virulence factors associated with EAEC intestinal infections.To understand if the presence of pAA could contribute to the increase o…
The understanding of the main role of goblet cells was only restricted to the production of mucins; however, this concept has changed drastically because of the discovery of populations of goblet cells exerting metabolic functions and the defense that place them now as the central players in the intestinal homeostasis. Altered goblet cell function could lead to a dysfunctional mucus barri…
