Abstract:
Objective:To study the different region (DFR) genotyping of 15 strains of Yersinia pestis from Inner Mongolia. Methods:Fifteen strains of Yersinia pestis isolated from Otog Banner and Darhan Muminggan Joint Banner in Meriones unguiculatus plague foci in Inner Mongolia Plateau, Zhengxiangbai Banner in Spermophilus dauricus plague foci in the Songliao Plain in 2019 were amplified by PCR, and identified DFR genotyping. Results:Two strains of Yersinia pestis in Otog Banner jointly deleted DFR loci 1, 6, 7, 13, 15, 16, 17, 18, 23, and 13 strains of Yersinia pestis in Darhan Muminggan Joint Banner and Zhengxiangbai Banner jointly deleted DFR loci 1, 6, 7, 12, 13, 15, 16, 17, 18 and 23. G17 and G20 were classified as genotyping by comparison with DFR locus distribution and genotyping results. Conclusion:The genotyping of Yersinia pestis in the natural foci of Meriones unguiculatus plague foci in Inner Mongolia Plateau and Spermophilus dauricus plague foci in the Songliao Plain is the same as that of the historical strain.
