Abstract: Objective To learn about the difference on the composition of Pgm+ and Pgm-cell of Yersinia pestis.Methods Using Jackson-burrow's medium and Congo red medium,we examined the numbers of Pgm+and Pgm- cell of 311 Yersinia pestis from various natural foci in China.Results The Pgm+ rate of Y.pestis in Microtus fuscus.Xilinguole plateau,Northern on east and west of mountain Tianshan ecotypes were the highest.There were Pgm+ cells in every Y.pestis except A and B ecotype in Kunlun mountain.Conclusion The Pgm+ phenotype of Y.pestis in Microtus fuscus,Xilinguole plateau,Northern on east and west of mountain Tianshan ecotypes were very stable.
摘要: 目的对从我国不同类型疫源地分离的鼠疫菌进行色素沉着因子(Pgm)表型的分析。方法用氯化血红素培养基或刚果红培养基培养鼠疫菌,对不同颜色的菌落进行计数,计算鼠疫菌Pgm的阳性率。结果我国10个疫源地的16个生态型和新发现的四川青海田鼠型,除昆仑山A、B型外,其他各型的菌株均含有Pgm+菌,以青海田鼠型、锡林郭勒高原型、北天山东段型、北天山西段A型、北天山西段B型菌株的Pgm+率为高,Pgm+菌株>90%。结论青海田鼠型、锡林郭勒高原型、北天山东段型、北天山西段A型、北天山西段B型菌株的Pgm+表型稳定。
