Method Acoording to the analysis of the conservative and variable regions in bacterial 16S rRNA genes , we designed universal primers for all bacteria and specific primers for most gram-positive and gram-negtive bacteria .

  • 方法 通过对多数病原菌16S rRNA基因保守区和变异区的序列分析 ,设计通用引物和革兰阴性菌及革兰阳性菌的特异性引物分别作为外侧和内侧引物,建立了对不同细菌的16S rRNA基因进行多重半套式PCR扩增方法;
