Extensive genomic diversity and selective conservation of virulence determinants in enterohemorrhagic Escherichia coli strains of O157 and non O157 serotypes [PDF]

, 2007
Background: Enterohemorrhagic Escherichia coli (EHEC) O157 causes severe food-borne illness in humans. The chromosome of O157 consists of 4.1 Mb backbone sequences shared by benign E.

EHEC – und was dann? [PDF]

Journal für Verbraucherschutz und Lebensmittelsicherheit, 2011
Wer in diesem Jahr uber Himmelfahrt oder an den Pfingstfeiertagen durch die Berliner Innenstadt gewandelt ist, wird vielleicht in einem Regierungsgebaude in der Mauerstrase auffallende Geschaftigkeit festgestellt haben. Hier befand sich in diesen Tagen die Task Force EHEC, die ,,wie eine Sonderkommission der Polizei‘‘ arbeitete und sich auf der ,,Spur ...

Interaction d'Escherichia coli entérohémorragique (EHEC) avec Acanthamoeba castellanii et rôle du régulon Pho chez les EHEC [PDF]

, 2014
Les EHEC de sérotype O157:H7 sont des agents zoonotiques d’origine alimentaire ou hydrique. Ce sont des pathogènes émergeants qui causent chez l’humain des épidémies de gastro-entérite aiguë et parfois un syndrome hémolytique-urémique.

Identification and prevalence of in vivo-induced genes in enterohaemorrhagic Escherichia coli

Virulence, 2019
Enterohaemorrhagic Escherichia coli (EHEC) are food-borne pathogens responsible for bloody diarrhoea and renal failure in humans. While Shiga toxin (Stx) is the cardinal virulence factor of EHEC, its production by E.

Ribosome State Distributions Define Escherichia coli Persister Physiology: Links to Formation, Stress Responses, and Resuscitation Dynamics. [PDF]

Microb Biotechnol
The AUCS70/AUCS100 ratio, derived from ribosome sedimentation profiling, quantitatively distinguishes Escherichia coli persisters from growing cells across multiple stress conditions and identifies RMF as the primary target for anti‐persistence strategies. ABSTRACT Persister cells survive antibiotic exposure and contribute to infection relapse, yet the
