Detection of a novel repeated sequence useful for epidemiological typing of pathogenic Yersinia enterocolitica.

Strains (n = 203) of Yersinia species were used in genotyping and PCR experiments in order to evaluate the genotyping potential of the YeO:3RS probe. This probe comprises a 12.5 kb genomic fragment of the Y.

Survival of Yersinia enterocolitica in Fermented Sausages Manufactured With Different Levels of Nitrite and Different Starter Cultures.

The ability of Yersinia enterocolitica 0:3 to grow and survive during the manufacture of fermented sausages made with 0, 50, 80, 100, and 120 mg/kg added sodium nitrite and three different commercial starter cultures was determined. The sausage mass was inoculated to contain 1.7 × 10 of Y.
