Abstract:
Objective To study the features of Yersinia pestis(Y.pestis)in areas along Qinghai-Tibet Railroad in Qinghai Province.Methods To identify the biologic types and the molecular biological feathers of Y.pestis isolated from areas along Qinghai-Tibet Railroad in Qinghai from 2001-2006.Results All the tested Y.pestis was biologically of classical type and ecologically of Qinghai-Tibet plateau type.The Y.pestis had high virulence.The Y.pestis of 65×106 plasmids was distributed in the Tanggula area,the Y.pestis of 52×106plasmids,in Tianjun and Delingha areas.The Y.pestis srains carried 52 × 106 plasmids.except the two containing 65 X 106 plasmids in Wulan County.The genetic type of Y.pestis in Tanggula was type 5 and that in Zongwulong of Delingha,Saishike,Keke,Tongpu of Wulan was type 8 except 2 strains of Y.pestis isolated from woodchuck and the patients in Dananwan of Tongpu,Wulan County were type 15.Conclusion The Y.pestis in the area along Qinghai-Tibet Railroad in Qinghai belongs to Qinghai-Tibet plateau type with high virulence.
