Background The ability of Shigella to invade, colonize, and eventually kill host cells is influenced by many virulence factors. However, there is no analysis of related genes in Jiangsu Province of China so far. Shigella flexneri was collected from 13 cities of Jiangsu Province through the provincial Centers for Disease Control (CDC) for analysis of distribution of major virulence genes (ipaH, ...
We developed a polymerase chain reaction method in order to detect and identify both Yersinia pseudotuberculosis and pathogenic Yersinia enterocolitica. Polymerase chain reaction was performed by using a mixture of primers against the inv gene from Y. pseudotuberculosis and the ail gene from pathogenic Y. enterocolitica. Further addition of primers against the plasmid-coded virF gene from Y. en...
The genome of Shigella, a gram negative bacterium which is the causative agent of bacillary dysentery, shares strong homologies with that of its commensal ancestor, Escherichia coli. The acquisition, by lateral gene transfer, of a large plasmid carrying virulence determinants has been a crucial event in the evolution towards the pathogenic lifestyle and has been paralleled by the occurrence of ...
