In tropical to temperate environments, fecal indicator bacteria (FIB), such as enterococci and
Escherichia coli, can persist and potentially multiply, far removed from their natural reservoir …

Horizontal genetic transfer (HGT) has played an important role in bacterial evolution at least
since the origins of the bacterial divisions, and HGT still facilitates the origins of bacterial …

Escherichia coli is mostly a commensal of birds and mammals, including humans, where it
can act as an opportunistic pathogen. It is also found in water and sediments. We …

The Escherichia coli species represents one of the best-studied model organisms, but also
encompasses a variety of commensal and pathogenic strains that diversify by high rates of …

Escherichia coli is naturally present in the intestinal tracts of warm-blooded animals. Since
E. coli is released into the environment through deposition of fecal material, this bacterium is …

It is a standard practice to test for the signature of homologous recombination in studies
examining the genetic diversity of bacterial populations. Although it has emerged that …

Given the significant spatial and temporal heterogeneity in antimicrobial resistance
distribution and the factors that affect its evolution, dissemination, and persistence, it is …

Abstract Background Extraintestinal pathogenic Escherichia coli (ExPEC) strains represent a
huge public health burden. Knowledge of their clonal diversity and of the association of …

Escherichia coli is familiar to biologists as a classical model system, ubiquitous in molecular
biology laboratories around the world. Outside of the laboratory, E. coli strains exist as an …

Background Escherichia coli strains are commonly found in the gut microflora of warm-
blooded animals. These strains can be assigned to one of the four main phylogenetic …
