| 摘 要： | 目的 对来自全国不同疫源地、不同生态型的１０３株鼠疫耶尔森氏菌进行基因分型研究。方法 用随机扩增多态性ＤＮＡ技术（ＲＡＰＤ）。结果 将鼠疫耶尔森氏菌分成两种基因型别：全国大部分菌株为ＲＡＰＤ－１型，青海省境内的大部分菌株为ＲＡＰＤ－２型。结论 不同生态型的鼠疫耶尔森氏菌基因结构存在差异，为鼠疫耶尔森氏菌的基础研究和防治提供依据。

| Abstract: | OBJECTIVE: To study the type of 103 Y. pestis strains that isolated from different plague foci and different ecological types. METHOD: 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. CONCLUSION: The genome structures of different ecotype Y. pestis were different providing the foundation of further research and prevention of plague. |
