B(来源：dd9dAB94C论文网www.abclunwen.com)OXAIR-PCR指纹图谱的聚类结果显示：全部供试菌株在50％的相似性水平上分为47群，与数值分类的结果相比较，其分群的结果更分散，在数值分类80％相似性水平上位于同一表观群的供试未知菌株大多分布于几个综合的BOXAIR-PCR群内；另外在数值分类中来自同一个种的已知根瘤菌参比菌株几乎都聚在同一个表观群，而在BOXAIR-PCR分析中，已知参比根瘤菌的同一个种内的大部分菌株都单独成群。

To obtain a better understanding of the microbiota inhabiting the intestinal tract of wood-feeding lower termites, the European subterranean termite, Reticulitermes santonensis (Isoptera: Rhinotermitidae), was used as a model system. The diversity and structure of the bacterial community in the different niches of the gut, as well as the distribution and location of major bacterial phylotypes within the intestinal tract was evaluated using various molecular techniques such as clonal analysis, DNA fingerprinting, and fluorescence in situ hybridization. In addition, the symbiotic bacteria associated with the flagellate, Pyrsonympha vertens in the gut of the closely related Eastern subterranean termite, Reticulitermes flavipes , were phylogenetically characterized.
