PCR detection of virulence genes in Yersinia enterocolitica and Yersinia pseudotuberculosis and investigation of virulence gene distribution

Article Abstract:

This article describes the development of a polymerase chain reaction based assay for detecting plasmid- and chromosome-borne five virulence genes of Yersinia enterocolitica and Y. pseudotuberculosis and their distribution in other Yesinia isolates. Data indicate that 40 isolates are positive for inv gene, 88% containing the virulence plasmid genes yadA and IcrF.

virF-Positive Yersinia pseudotuberculosis and Yersinia enterocolitica found in migratory birds in Sweden

Article Abstract:

The authors have investigated fecal samples from the migratory birds. The occurrence of pathogenic Yersinia pseudotuberculosis and Y. enterocolitica in the birds' feces, and the virulence properties of isolated Yersinia species have been examined and discussed.

PCR-restriction fragment length polymorphism analysis of the phospholipase B (PLB1) gene for subtyping of Cryptococcus neoformans isolates

Article Abstract:

The polymerase chain reaction-restriction length polymorphism profiles of the phospholipase B gene fragment of 1,970 base pairs groups Cryptococcus neoformans isolates into their respective varieties and eight molecular types.
