The molecular phylogeny of the gyrB gene: A molecular marker for systematic characterization of the genus Yersinia

Abstract

Phylogenetic analysis of 198 Yersinia strains belonging to 16 species was conducted using 430 bp of the gyrB gene to determine inter-species relatedness and to aid in rapid and accurate species identification. Based on the phylogenetic data, a genetic distance threshold value of 0.025 ± 0.001 was proposed for future prediction of strains of different species or genomospecies in the genus Yersinia. We have demonstrated that partial gyrB gene sequencing can be used to accurately and insightfully construct the phylogeny of the genus Yersinia. © 2012 Springer Science+Business Media New York.
