Comparative pathogenesis of Yersinia enterocolitica biotypes
Yersinia enterocolitica is a well known food-borne bacterium which belongs to the Enterobacteriaceae family. Y. enterocolitica is pathogenic for humans and it causes a wide spectrum of diseases ranging from self-limiting gastrointestinal diseases to fatal sepsis depending on the age and the …

Epidemiology and comparative analysis of Yersinia in Ireland
… per year. At the same time pathogenic Yersinia enterocolitica is recovered from pigs (main source of pathogenic Y. enterocolitica) at the levels similar to that observed in Yersinia endemic countries. Introduction of Yersinia selective culture procedures may increase Yersinia isolation rates. To …

Ein Beitrag zur Epidemiologie und Verbreitung von pathogenen Yersinia enterocolitica 4/O:3 in Münchener Metzgereien
… Berührung kommen. Die Proben wurden auf Yersina enterocolitica untersucht. Die Nachweismethode erfolgte in Anlehnung an die ISO DIN 10273: „Microbiology – General guidance for the detection of presumptive pathogenic Yersinia enterocolitica“ und an den Vorschlag des NCFA (Nordic Committee On Food …

Die Verbreitung der Yersiniose beim Menschen im Großraum München unter Berücksichtigung von Schweinefleisch und Schlachtnebenprodukten als mögliche Infektionsquelle
Yersinia enterocolitica of bioserovar 4/O:3 is the most common pathogenic type found in pigs and pork including edible offal in Southern Germany. Limited epidemiological data is available of human Y. enterocolitica infections in Bayern. The sources and transmission routes of yersiniosis are not …

Characterisation of YGT a novel Type III secretion system in Biotype 1A Yersinia enterocolitica strain YE53/03
Biotype (BT) 1A Yersinia enterocolitica is considered a group of organisms that is harmless given the lack of classical virulence factors, characteristic of pYV bearing strains. BT 1A Y. enterocolitica strains are common in the environment and in livestock, particularly the pig, with no adaption to …

The evolution of the autoantibody response in Graves’ disease
… such factor is the infectious agent, Yersinia enterocolitica. Two high affinity TSAbs, (KSAbl, lgG2t>/K; KSAb2, IgGaa/K), developed from an experimental murine model of GD, share common germline Ig genes and thus are derived from the same precursor B cell clone which diversified through somatic …

Evolutionary dynamics of the Yersinia enterocolitica complex
… Yersinia pseudotuberculosis and Yersinia enterocolitica as well as environmental species. The evolutionary history of Y. pestis has been well documented, but information on the evolutionary relationship between the other Yersiniae is less characterized. Y. enterocolitica is a diverse …

Utilization of ferrioxamine microarrays for the rapid detection of pathogenic bacteria
… concentration and exposure time. <em>Y. enterocolitica</em> could be detected as low as 102 cfu/mL after a 1-hour exposure; conversely, several pathogenic bacteria could be detected after just 30 seconds of exposure at 107 cfu/mL. Additional studies on pathogen detection at refrigeration …
