为了解在内蒙古分离的炭疽杆菌与其它地区的菌株之间有无差异 ,采用 PCR加酶切的方法对所选用的被试菌进行了 16 S和 2 3S r RNA基因间段分析。结果发现所有实验菌株间的 PCR及酶切图谱一致 ,说明我区的炭疽杆菌与其它地区的菌株在遗传学上具有同源性 ,无本质差异。
In order to find out whether there is any difference between Bacillus anthracis isolates in Inner Mongolia and those in other areas, the 16 S and 23S rRNA gene segments of the tested bacteria were analyzed by PCR plus restriction enzyme digestion. The results showed that all the experimental strains of PCR and enzyme digestion patterns consistent, indicating that mycobacterium Bacillus anthracis and other regions of the genetically identical, no essential differences.
