Escherichia coli is a commensal of the vertebrate gut that is increasingly involved in various
intestinal and extra-intestinal infections as an opportunistic pathogen. Numerous pathotypes …

SUMMARY Extraintestinal pathogenic Escherichia coli (ExPEC) strains are responsible for a
majority of human extraintestinal infections globally, resulting in enormous direct medical …

The genus Escherichia is composed of Escherichia albertii, E. fergusonii, five cryptic
Escherichia clades and E. coli sensu stricto. Furthermore, the E. coli species can be divided …

There is extensive genetic substructure within the species E scherichia coli. In 2000 a simple
triplex PCR method was described by C lermont and colleagues that enables an E. coli …

Accurate strain identification is essential for anyone working with bacteria. For many
species, multilocus sequence typing (MLST) is considered the “gold standard” of typing, but …

The phylogeny of the Escherichia coli species, with the identification of seven phylogroups
(A, B1, B2, C, D, E and F), is linked to the lifestyle of the strains. With the accumulation of …

Escherichia coli is one of the most well-studied bacterial species, but several significant
knowledge gaps remain regarding its ecology and natural history. Specifically, the most …

The primary habitat of Escherichia coli is the vertebrate gut, where it is the predominant
aerobic organism, living in symbiosis with its host. Despite the occurrence of recombination …

Multilocus sequence typing reveals that many bacterial species have a clonal structure and
that some clones are widespread. This underlying phylogeny was not revealed by pulsed …

Quantitative evidence for the risk of zoonoses and the spread of antimicrobial resistance
remains lacking. Here, as part of the UrbanZoo project, we sampled Escherichia coli from …
