ABSTRACT
Objective To detect the Yersinia pestis plasmid and molecular weight along the Qinghai-Tibet Railway.Methods Yersinia pestis plasmids molecular weight detected and analyzed using alkaline lysis,phenol-chloroform extraction of Yersinia pestis plasmid by agarose gel electrophoresis.Results The 18 Yersinia pestis strains of Qinghai-Tibet Railway contained 6×106,45×106,52×106,65×106,92×106plasmid,varing in the range of the 52×106-92×106.Conclusions The Yersinia pestis of Qinghai-Tibet Railway has a standardplasmid graphics,with the biggest Yersinia pestis plasmid changing in a certain regular degree,which providessignificance in the study of plague natural foci of the spatial structure and the genetic.characteristics of Yersiniapestis.
