Identification of the Pseudomonas aeruginosa 1244 pilin glycosylation site.

abstract：: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 number of virulence phenotypes, it is not yet clear which of these phenotypes descended from Y. pseudotuberculosis and which were acquired in...
