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 that represent groups of strains with specific pathogenic characteristics have been described based on heterogeneous and ...
coli has also been widely exploited as a cloning host in recombinant DNA technology. But E. coli is more than just a laboratory workhorse or harmless intestinal inhabitant; it can also be a highly versatile, and frequently deadly, pathogen. Several different E. coli strains cause diverse ...

UropathogenicEscherichiacoliis the main etiological agent of UTI; this pathogen has a whole arsenal ofvirulence factorsthat have allowed it to adapt tourinarytract. In addition, its multidrug-resistance represents a true health challenge, since therapeutic options are considerably reduced (1,15). Altho...
coli/Shigella ancestor was likely a facultative or opportunistic pathogen. The extant commensal strains diverged relatively late and appear to by the result of reductive evolution of genomes. We also identify clade distinguishing features and their associated genomic regions within each phylogroup. Such ...
Escherichia coli is an important species of bacteria that can live as a harmless inhabitant of the guts of many animals, as a pathogen causing life-threatening conditions or freely in the non-host environment. This diversity of lifestyles has made it a p
In vivo labeling of Escherichia coli JA200 pLC 11-8 resulted in 32P incorporation into enolase as demonstrated by immunoaffinity chromatography and electrophoresis followed by autoradiography. Complete acid hydrolysis, followed by thin layer chromatography was employed for determination of the phosphoamino ...
[6]. Thus, the outcome and severity ofE. colimastitis was mainly attributed to environmental factors and the innate immune response of the cow reacting to pathogen-associated molecular patterns (PAMPs) (most prominently lipopolysaccharide, LPS) rather than the virulence potential of the invading ...
Escherichia coli is both a harmless commensal in the intestines of many mammals, as well as a dangerous pathogen. The evolutionary paths taken by strains of this species in the commensal-to-pathogen transition are complex and can involve changes both in
