Molecular evolution of pathogenicity-island genes in Pseudomonas viridiflava.
The bacterial pathogen Pseudomonas viridiflava possesses two pathogenicity islands (PAIs) that share many gene homologs, but are structurally and phenotypically differentiated (T-PAI and S-PAI). These PAIs are paralogous, but only one is present in each isolate. While this dual presence/absence polymorphism has been shown to be maintained by balancing selection, little is known about the molecu...
متن کاملPathogenicity island-directed transfer of unlinked chromosomal virulence genes.
In recent decades, the notorious pathogen Staphylococcus aureus has become progressively more contagious, more virulent, and more resistant to antibiotics. This implies a rather dynamic evolutionary capability, representing a remarkable level of genomic plasticity, most probably maintained by horizontal gene transfer. Here we report that the staphylococcal pathogenicity islands have a dual role...
متن کاملThe Yersinia high-pathogenicity island.
A pathogenicity island present only in highly pathogenic strains of Yersinia (Y. enterocolitica 1B, Y. pseudotuberculosis I and Y. pestis) has been identified on the chromosome of Yersinia spp. and has been designated High-Pathogenicity Island (HPI). The Yersinia HPI carries a cluster of genes involved in the biosynthesis, transport and regulation of the siderophore yersiniabactin. The major fu...
متن کاملPIPS: Pathogenicity Island Prediction Software
The adaptability of pathogenic bacteria to hosts is influenced by the genomic plasticity of the bacteria, which can be increased by such mechanisms as horizontal gene transfer. Pathogenicity islands play a major role in this type of gene transfer because they are large, horizontally acquired regions that harbor clusters of virulence genes that mediate the adhesion, colonization, invasion, immun...
متن کاملSiderophore production by Pasteurella multocida.
Pasteurella multocida grown under conditions of iron deprivation secreted into the culture medium a growth-enhancing factor which functioned as a siderophore. The siderophore was found to be neither a phenolate nor a hydroxamate by chemical tests and bioassays and was given the trivial name multocidin. Multocidin was partially purified and found to be a highly polar, nonaromatic, and dialyzable...
