The 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 کاملYAPI, a new Yersinia pseudotuberculosis pathogenicity island.
Pathogenicity islands (PAIs) are chromosomal clusters of pathogen-specific virulence genes often found at tRNA loci. In the Yersinia pseudotuberculosis 32777 chromosome, we characterized a 98-kb segment that has all of the characteristic features of a PAI, including insertion in a (phenylalanine) tRNA gene, the presence of a bacteriophage-like integrase-encoding gene, and direct repeats at the ...
متن کاملStreptomyces turgidiscabies Car8 contains a modular pathogenicity island that shares virulence genes with other actinobacterial plant pathogens.
Streptomyces turgidiscabies Car8 is an actinobacterium that causes the economically important disease potato scab. Pathogenesis in this species is associated with a mobile pathogenicity island (PAISt) that site specifically inserts into the bacA gene in Streptomyces spp. Here we provide the 674,223 bp sequence of PAISt, which consists of two non-overlapping modules of 105,364 and 568,859 bp. Th...
متن کاملThe genomic organization of plant pathogenicity in Fusarium species.
Comparative genomics is a powerful tool to infer the molecular basis of fungal pathogenicity and its evolution by identifying differences in gene content and genomic organization between fungi with different hosts or modes of infection. Through comparative analysis, pathogenicity-related chromosomes have been identified in Fusarium oxysporum and Fusarium solani that contain genes for host-speci...
