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 …

Evidence of Bacteriocinogeny in Yersinia Ruckeri
Twelve isolates of Yersinia ruckeri were examined for bacteriocinogeny. Seven isolates produced an antagonistic substance that inhibited five other Y. ruckeri isolates, as demonstrated by the modified double layer method. Producer isolates were immune to the antagonistic substance. Extracts …

Carbon Catabolite Regulation of Yersinia pestis Pathogenesis
… with different aspects of the infectious cycle, Yersinia pestis evokes adaptive responses to concertedly regulate gene expression. The overall objective of this project was to ascertain the impact of carbon catabolite regulation upon Y. pestis pathogenesis. Specifically, this research encompassed …

Evolutionary dynamics of the Yersinia enterocolitica complex
The genus Yersinia consists of a heterogeneous collection of organisms, comprising the highly pathogenic species Yersinia pestis, enteropathogens Yersinia pseudotuberculosis and Yersinia enterocolitica as well as environmental species. The evolutionary history of Y. pestis has been well documented, …

Untersuchungen zur Yersinia enterocolitica-stimulierten Genexpression in Epithelzellen
… können sie eine Entzündungsreaktion einleiten. Yersinia enterocolitica ist ein enteropathogener, vorwiegend extrazellulär lokalisierter Erreger, der eine akute Enterokolitis, Sepsis und immunologische Folgeerkrankungen verursacht. Die Rolle der intestinalen Epithelzellen bei der Infektion mit Y. …

Epidemiology and comparative analysis of Yersinia in Ireland
… enteric zoonosis caused by enteropathogenic Yersinia species. Although yersiniosis is predominantly associated with gastroenteric forms of infection, extraintestinal forms are often reported from the elderly or patients with predisposing factors. Yersiniosis is often reported in countries …

Dominant Suppression of Early Innate Immune Mechanisms by Yersinia pestis
… within a few hours of infection, but <italic>Yersinia pestis</italic> is strikingly different: the first 36 hours of infection are characterized by rapid bacterial replication in the lung without generating appreciable levels of proinflammatory cytokines/chemokines, histological changes in …

In Vivo Gene Expression Profiling of the Plague Bacillus, Yersinia Pestis
Yersinia pestis, the causative agent of plague, can be transmitted by infected-flea bite or inhaled aerosol. Both routes of infection have a high mortality rate, and pneumonic infections of Yersinia pestis represent a significant fear as a tool of bioterrorism. Understanding the transcriptional …

Der Einfluss von Yersinia-Effektoren auf podosomale Adhäsionsstrukturen primärer humaner MAkrophagen
… mit unterschiedlichen Mutanten der Spezies Yersinia enterocolitica für verschiedene Zeiten infiziert. Nach Färbung der Zellen mit Rhodamin-Phalloidin wurde die Anzahl der verbliebenen Zellen mit Podosomen im konfokalen Mikroskop ermittelt und statistisch ausgewertet. Es konnte erstens …

Untersuchungen zur Produktion und Chaperoninteraktion von Yersinia YopE und SycE mittels Reporterfusionstechnologie
Yersinia enterocolitica produzieren Pathogenitätsfaktoren, die es ihnen ermöglichen, an die Zellen des Wirtes zu adhärieren, diese zu invadieren und protektive Immunantwort des Wirtes zu modifizieren. Dazu gehören die Yersinia outer proteins (YOP), die durch den Typ III Sekretionsweg über die …

Uncovering novel pathogenicity-associated loci among Yersinia enterocolitica species by subtractive hybridization
… zu finden, die spezifisch für hochpathogene Yersinia enterocolitica Stämme sind. Hierfür wurde die DNA eines nicht pathogenen „Treiber”-Stammes (Y. enterocolitica NF-O, Biotyp 1A) gegen die DNA eines hochpathogenen „Tester”-Stammes (Y. enterocolitica WA-314, Biotyp 1B) subtrahiert. Mit Hilfe …

Early pathogenesis of Yersinia ruckeri infections in rainbow trout (Oncorhynchus mykiss, Walbaum)
Yersinia ruckeri is the causative agent of yersiniosis or enteric redmouth disease (ERM) and causes significant losses in salmonid aquaculture worldwide. Although infection with this agent has been reported in other fish species, salmonids and especially rainbow trout are most susceptible to ERM. …

Purification, immunogenicity and protective potency of the F1 antigen from <i>Yersinia pestis</i>
<i>Yersinia pestis</i>, an organism endemic in much of the world, is the causative agent of pneumonic and bubonic plague. The disease is severe with a high mortality rate. Most plague vaccines are formalised whole cells, which give limited and short-lived immunity. An acellular vaccine could prove …

A Structural Basis for Host Cytoskeletal Disruption and Virulence by Yersinia Protein Kinase A
<p>Yersinia spp. cause gastroenteritis and the plague, representing historically devastating pathogens that are currently an important biodefense and antibiotic resistance concern. Although several antibiotic therapies exist, the emergence of strains that have garnered multiple drug resistances in …

Inaktivierung von Salmonella Typhimurium und Yersinia enterocolitica auf Schwarte und Schweinelachs mittels gepulsten Lichts
… ssp. auf Schwarte und Schweinelachs. Bezüglich Yersinia ssp. lagen noch gar keine Studien vor. Ziel der Untersuchungen: Ziel dieser Arbeit war es, die Inaktivierung beider Erreger auf oben genannten Matrices zu testen und, unter Berücksichtigung chemischer und sensorischer Attribute der Produkte …

Functional expression and initial biochemical characterization of Yp-NhaP, cation-proton antiporter from Yersinia pestis
… antiporter from the dangerous human pathogen Yersinia pestis. We expressed Yp-NhaP in its functional form in the antiporter-deficient strain of E. coli, TO114. When assayed in inside-out sub-bacterial membrane vesicles, Yp-NhaP acted as an electroneutral cation/proton antiporter, exchanging …
