Abstract
On the basis of comparison between the genome-wide sequences of Altaic and Hissar strains of non-main subspecies and strains from Talas high-mountain plague focus, identified have been two novel DNA-targets, the usage of which provides for easy rapid subdivision of these closely-related strains of non-main subspecies that fall into separate phylogenetic brunches of plague agent evolution, applying PCR assay. One of the targets is allocated to intergenic region between YPO3333 and YPO3332 genes. In strains of altaica ssp. it contains 122 bps deletion. The other target is YPO2412 gene region which contains 72 bps deletion in Talas strains. Special primers for DNA-targets have been designed. Established have also been test specifications. Efficacy of the method for differentiation between the strains of Altaic-Hissar group of non-main subspecies is validated on 97 Y. pestis strains of various ssp.
