The airn of this study is to carry out genotyping of 61 Y.pestis strains isolated from Marmota baibacina-Spermophilus undulates Plague Focus of Tianshan Mountains in China. Primer pairs targeting the 22 DFRs were designed for detecting the genotypes of 61 strains. As a result, 61 strains of Y.pestis were divided into four genotypes 1, 2, 3, and 4. Genotypes 1, 2 and 3 were found from west part in Northern Tianshan Mountains Plague Focus, but type 1 was only from Nileke county. The type of strains from Aheqi was different from those of Atushi counties in Southern Tianshan Mountains and similar to strains in Northern Tianshan Mountains Plague Focus. The type 4 distributed over Atushi county, which was identical with that of strains from Marmota caudae Plague Focus of the Pamiri Plateau. It is concluded that geonotyping is identical with ecotyping made by Shuli Ji. Tianshan Mountains Plague Focus and Marmota caudae Plague Focus of the Pamiri Plateau have a cross spreading profile.

The type of the strains from Aheqi was different from those of Atushi counties in Southern Tianshan Mountains and similar to Bridges in Northern Tianshan Mountains Plague Focus. The type 4 distributed over Atushi county, which was identical with that of Bills from Marmota caudae Plague Focus of the Pamiri Plateau It is said that that pattern is identical with ecotyping made by Shuli Ji. Tianshan Mountains Plague Focus and Marmota caudae Plague Focus of the Pamiri Plateau have a cross spreading profile.
