The transformation of the enteropathogenic bacterium Yersinia pseudotuberculosis into the
plague bacillus, Yersinia pestis, has been accompanied by extensive genetic loss. This …

Yersinia pestis, the causative agent of plague, has recently diverged from the less virulent
enteropathogen Yersinia pseudotuberculosis. Its emergence has been characterized by …

The three pathogenic Yersinia species: Y. pestis, Y. pseudotuberculosis, and Y.
enterocolitica are closely related, but differ in their mode of infection. Both Y. enterocolitica …

Highly pathogenic strains of Yersinia pestis, Y. pseudotuberculosis, and Y. enterocolitica are
characterized by the possession of a pathogenicity island designated the high-pathogenicity …

Pathogenicity islands (PAIs) are chromosomal clusters of pathogen-specific virulence genes
often found at tRNA loci. In the Yersinia pseudotuberculosis 32777 chromosome, we …

Plague, one of the most devastating diseases of human history, is caused by Yersinia pestis.
In this study, we analyzed the population genetic structure of Y. pestis and the two other …

The pathogenic Yersinia species, Y. pseudotuberculosis, Y. enterocolitica, and Y. pestis, are
zoonotic agents that cause disease in humans ranging from mild gastroenteritis to life …

Yersinia pestis, the agent of plague, has arisen from a less virulent pathogen, Yersinia
pseudotuberculosis, by a rapid evolutionary process. Although Y. pestis displays a large …

Yersinia pseudotuberculosis localizes to the distal ileum, cecum, and proximal colon of the
gastrointestinal tract after oral infection. Using signature-tagged mutagenesis, we isolated …

Pathogenicity islands (PAIs) have been identified in several bacterial species. A PAI called
high‐pathogenicity island (HPI) and carrying genes involved in iron acquisition …
