[Study on the application of random amplified polymorphic DNA in Yersinia pestis genotyping].
OBJECTIVE
To study the type of 103 Y. pestis strains that isolated from different plague foci and different ecological types.


METHODS
Random amplified polymorphic DNA (RAPD) was used.


RESULTS
Y. pestis were divided into two RAPD types: most strains that isolated from elsewhere in the country belonged to RAPD-1 type, while most strains that isolated from Qinghai province were RAPD-2 type.


CONCLUSIONS
The genome structures of different ecotype Y. pestis were different providing the foundation of further research and prevention of plague.
