Although Escherichia coli can be an innocuous resident of the gastrointestinal tract, it also
has the pathogenic capacity to cause significant diarrheal and extraintestinal diseases …

Escherichia coli is a versatile bacterial species that includes both harmless commensal
strains and pathogenic strains found in the gastrointestinal tract in humans and warm …

Few microorganisms are as versatile as Escherichia coli. An important member of the
normal intestinal microflora of humans and other mammals, E. coli has also been widely …

Escherichia coli associated with urinary tract infections and bacteremia has been intensively
investigated, including recent work focusing on the virulent, globally disseminated, multidrug …

In this review, we focus on a group of mobile genetic elements designated pathogenicity
islands (PAI). These elements play a pivotal role in the virulence of bacterial pathogens of …

Gram-negative bacteria possess an outer membrane layer which constrains uptake and
secretion of solutes and polypeptides. To overcome this barrier, bacteria have developed …

Enteric bacterial pathogens pose significant threats to human health; however, the
mechanisms by which they infect the mammalian gut in the face of daunting host defenses …

Background: It is not clear which species of bacteria may be involved in inflammatory bowel
disease (IBD). One way of determining which bacteria might be likely candidates is to use …

Escherichia coli is the most abundant facultative anaerobic gram-negative bacterium of the
intestinal microffora, naturally colonizing the mucous layer of the colon. A conserved core …

Enteropathogenic Escherichia coli (EPEC) was the first pathovar of E. coli to be implicated in
human disease; however, no EPEC strain has been fully sequenced until now. Strain …
