To develop an effective method to isolate an injured pathogenic Yersinia enterocolitica O:8 organism from environmental samples, we compared the isolation of freeze-injured and non-injured Y. enterocolitica O:8 and found that the isolation was more successful when immuno-magnetic separation (IMS) with anti-Y. enterocolitica O:8 antibody was used. Plating onto cefsulodin-irgasan-novobiocin (CIN)...

Brown rats (Rattus norvegicus) have been identified as potential carriers of Yersinia enterocolitica and Y. pseudotuberculosis, the etiological agents of yersiniosis, the third most reported bacterial zoonosis in Europe. Enteropathogenic Yersinia spp. are most often isolated from rats during yersiniosis cases in animals and humans, and from rats inhabiting farms and slaughterhouses. Information...

All 250 children presenting with diarrhoea at 2 teaching hospitals in Mosul, Iraq over a 9-month period were studied for the presence of Yersinia spp. in stools by cold-enrichment culture at 4 degrees C for 21 days. Pathogenicity of the isolated Yersinia was determined. Antibodies to Y. enterocolitica were raised for rapid Yersinia detection in the stool. Yersinia spp. were isolated from the st...

The cold-active restriction endonuclease YenI, an isoschizomer of PstI, was found in 12 of 14 Yersinia enterocolitica serotype O8 strains of different origins, but not in other serotypes of Y. enterocolitica, Yersinia pseudotuberculosis, or Yersinia pestis. In spite of the limited number of strains tested, the result suggests that the detection of YenI endonuclease or the gene might result in m...

Yersinia enterocolitica, which causes yersiniosis, is a bacterium that produces biofilms effectively. The inhibition of biofilm formation provides method for preventing infections with Y. enterocolitica. In this study, the inhibitory activity enterocolitica was investigated in library 140 edible plant methanol extracts including forest products. It identified could be inhibited by 12 plants, Ag...

Consumption of meat contaminated with Yersinia pestis can cause oropharyngeal plague in humans. Existing microbiological media designed for selective detection of Y. pestis in food are not satisfactory for that purpose. Expression of genetic determinants in Yersinia species including low calcium response (Lcr), colony size, crystal violet (CV) binding, Congo red (CR) uptake, autoagglutination (...

The consumption of food contaminated with Yersinia can lead to gastrointestinal infections. The cause for this so-called yersiniosis are the species Y. enterocolitica and Y. pseudotuberculosis. Yersinia are rod-shaped bacteria which are very common in our environment. The main reservoir for Yersinia enterocolitica are pigs, meaning that the bacteria can be found in raw pork. For Yersinia pseudo...
