Objective To study the genotype and epidemiological characteristics of Yersinia pestis in Hebei foci. Methods Primers were designed according to the confirmed 22 different segments (DFR), to genotype the 116 Y. pestis DNA of Hebei province. Results All of the strains lack these DFR of 01, 06, 07, 13, 15-18, to compare the genetic typing system of DFR, Y. pestis from Hebei province belong to the 17 genotype, distributed in the northern Kangbao county neighboring Huade, Baiqi, and Taipusiqi in the Inner Mongolia Autonomous Region. Conclusion The Y. pestis is stable genetically in Hebei plague foci, and have only one genotype, so the epidemic tends to stabilize.
Key words： Yersinia pestis; Different segments; Genetic typing
