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 …

Evolution is the hallmark of life. Descriptions of the evolution of microorganisms have
provided a wealth of information, but knowledge regarding “what happened” has precluded …

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 …

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 …

Escherichia coli sequence type 131 (ST131) is an extensively antimicrobial-resistant E. coli
clonal group that has spread explosively throughout the world. Recent molecular …

Extraintestinal pathogenic Escherichia coli (ExPEC) isolates are responsible for many
bloodstream infections. The aim of this study was to characterize E. coli isolated from the …

Uropathogenic Escherichia coli (UPEC) is the leading cause of urinary tract infections (UTIs)
worldwide, causing over 150 million clinical cases annually. There is currently no specific …

The intrinsic virulence of extra-intestinal pathogenic Escherichia coli is associated with
numerous chromosomal and/or plasmid-borne genes, encoding diverse functions such as …

It is important to study commensal populations of Escherichia coli because they appear to be
the reservoir of both extra-intestinal pathogenic E. coli and antibiotic resistant strains of E …

Introduction Escherichia (E.) coli can cause intestinal and extra-intestinal infections which
ranged from mild to life-threatening infections. The severity of infection is a product of many …
