[目的]了解野生川金丝猴(Rhinopithecus roxellana)肠道内生细菌的组成及其多样性.[方法]提取川金丝猴肠道内生细菌总DNA,选用细菌通用引物799F和1492R对总DNA进行16S rRNA基因特异性扩增,构建川金丝猴肠道内生细菌16S rRNA基因克隆文库,对阳性克隆进行限制性内切酶片段长度多态性(PCR-RFLP)分析,并对Hae Ⅲ酶切带谱菌株进行测序,构建系统发育树.[结果]根据酶切带谱分析和测序结果,将随机挑取的157个阳性克隆归为27个不同的可操作分类单元(OTUs)o系统发育分析表明这些克隆序列有62.10%属于厚壁菌门(Firmicutes),其中包括梭菌属(Clostridium)、Cellulosilyticum属、Robinsoniella属、Anaerofustis 属、Blautia属和Anaerovorax属,有37.90%属于未培养细菌.[结论]川金丝猴肠道内生细菌多样性丰富,并且可能存在新的分类单元.
Culture-independent analysis of intestinal microbial diversity from Rhinopithecus roxellana
[Objective] The composition and diversity of intestinal microbial diversity of wild Sichuan snub-nosed monkey (Rhinopithecus roxellana) were investigated.[Methods] The total DNA extracted from endophytic bacterial was performed 16S rRNA gene specific amplification by used bacteria-specific primers 799F and 1492R and constructed a clone library.Then,16S rRNA gene phylogenetic tree was established by analyzed positive clones used polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and by sequenced some of the clones.[Results] The 157 clones analyzed were grouped into 27 operational taxonomic units (OTUs),where the clone distribution was as follows:62.10% of Firmicutes which contained Clostridium,Cellulosilyticum,Robinsoniella,Anaerofustis,Anaerovorax and Blautia,37.90% of uncultured bacteria.[Conclusion] The intestine bacterial of wild Sichuan snub-nosed monkey has a rich diversity and maybe exist new taxon.
