摘要: 运用变性梯度凝胶电泳(DGGE)和实时荧光定量(q-PCR)技术分析6个年龄组恒河猴粪便样品中主要细菌情况,揭示肠道微生态特点。16S rRNA基因V3可变区PCR-DGGE指纹图谱显示条带丰富,割胶62条,克隆测序后与GenBank序列进行比对后构建进化树显示所有62个条带、43个OTUs属于4个门:厚壁菌门,放线菌门,拟杆菌门以及螺旋体门。PCR-DGGE图谱泳道相似性分析及主成分分析(PCoA)显示婴幼龄组和孕期组聚类明显。Q-PCR结果显示梭菌属细菌和双歧杆菌最为丰富,肠球菌属最少。梭菌属clusters ⅪⅤ,肠球菌属和拟杆菌-普氏菌属组间差异明显(P<0.01)。作为显示肠道健康水平标准的双歧杆菌和肠杆菌比值(B/E值)与同龄恒河猴相比,在孕期恒河猴组有明显的降低(P<0.01)。婴幼龄组和孕期组特点相似属首次发现。

Abstract: With the denaturing gradient gel electrophoresis(DGGE)and real-time quantitative PCR(q-PCR), we analyzed the predominant bacteria in fecal samples of 24 individuals divided into 6 groups. DGGE profiles showed abundant bands for the 16S rRNA gene V3 region, and the composition of the gut microbiota was apparently different in each group. Furthermore, a clustering between infant and pregnancy was shown by Principal Coordinate Analysis(PCoA). Identified in the DGGE gels by sequencing the V3 regions were overwhelmingly affiliated with Firmicutes, Actinobacteria and Bacteroidetes. Q-PCR indicated that Clostridium and Bifidobacterium were the dominant species, and the least dominant species was Enterococcus faecali. C.clustersⅪⅤ, E.faecalis and Bacteroides-Prevotella group have the most significant diversity among individuals(P<0.01)The Bifidobacteria /Enterobacteriaceae(B/E)ratio, which indicates microbial colonization resistance(CR)in the gut appeared to be lower than the peers, subadults and adults, in pregnancy(P<0.01). The study revealed the characterization of Rhesus Macaquesintestinal microbiota. The characteristics of infant gut microbiota are remarkably similar to those found of the pregnancy groups.
