ABSTRACT
<p><b>OBJECTIVE</b>To study the genotype distributions and epidemiological characteristics of Yersinia pestis in Gansu province.</p><p><b>METHODS</b>Primers were designed according to the confirmed 23 differential sections, to genotype the 202 Yersinia pestis DNA of Gansu province by PCR, and to analyze its distribution and epidemiological characteristics.</p><p><b>RESULTS</b>Yersinia pestis in Gansu province could be divided into eight genotypes 1b, 5, 7, 8, 13, 26, new genotype 1 (GS1) and new genotype 2 (GS2). They were distributed in various regions. 1b, 8 and GS1 genotypes of Yersinia pestis had been identified since 1960s but the 7, 13 and 26 genotypes had not been isolated for more than 40 years while GS2 and 5 genotypes had been isolated since 1990s.</p><p><b>CONCLUSION</b>1b, 8 and GS1 genotypes of Yersinia pestis continued to be violently prevalent since 1960s but 7, 13 and 26 genotypes had not been isolated for more than 40 years while GS2 and 5 genotypes had started to be popular since 1990s.</p>
