摘要
目的以健康雌性育龄期恒河猴为研究对象,采用16S rRNA宏基因组方法探讨雌性恒河猴月经周期异常与肠道微生物组成的相关性。方法将27只健康雌性恒河猴分为月经规律和不规律两组,分别采集两组实验猴卵泡期(follicular phase,FP)、排卵期(ovulatoryperiod,OP)和黄体期(lutealphase,LP)粪便样品,对16SrRNA基因的V3~V4高变区测序,分析比较两组实验猴月经周期肠道菌群结构及多样性。结果在门水平,规律组和不规律组猕猴在卵泡期、黄体期和排卵期3个不同时期均以厚壁菌门(Firmicutes)、变形菌门(Proteobacteria)和拟杆菌门(Bacteroidetes)为主要菌群,占比总和超过98%;在属水平以普雷沃菌属_9(Prevotella_9)、瘤胃球菌(Ruminococcaceae_UCG-002)、乳杆菌属(Lactobacillus)、普雷沃菌属_2(Prevotella_2)、考拉杆菌属(Phascolarctobacterium)、瘤胃球菌_UCG-005(Ruminococcaceae_UCG-005)、链球菌属(Streptococcus)、布劳特菌属(Blautia)、普雷沃菌属_NK3B31(Prevotellaceae_NK3B31_group)、理研菌属(Rikenellaceae_RC9_gut_group)为主;在黄体期规律组厚壁菌门(Firmicutes)占比高于不规律组,而拟杆菌门(Bacteroidetes)刚好相反。规律组3个阶段,螺旋体门(Spirochaetes)均高于不规律组(P<0.05)。结论月经周期规律与月经周期不规律的两组猕猴肠道微生物组成存在一定差异,为研究肠道细菌与排卵障碍提供一定的参考依据。
Objective Using healthy female reproductive-age rhesus macaques as the research subjects,we explored the correlation between menstrual cycle abnormalities and gut microbiota composition by using 16S rRNA metagenomic sequencing.Methods Twenty-seven healthy female rhesus macaques were divided into regular menstrual and irregular menstrual groups.Fecal samples were collected at follicular phase(FP),ovulation phase(OP)and luteal phase(LP)of the two groups.The structure and diversity of bacterial flora in different physiological periods were analyzed and compared between the two groups.Results At the phylum level,Firmicutes,Bacteroidetes,and Proteobacteria dominated the sample flora in the follicular,luteal,and ovulatory phases of the rhesus macaques in both the regular and irregular groups,with a combined percentage of more than 98%.At the genus level,the genus Prevotella_9,Ruminococcaceae_UCG-002,Lactobacillus,Prevotella_2,Phascolarctobacterium,Ruminococcaceae_UCG-005,Streptococcus,Blautia,Prevotellaceae_NK3B31_group,Rikenellaceae_RC9_gut_group were dominant.In the luteal phase the percentage of Firmicutes was higher in the regular group than in the irregular group,while the opposite was true for Bacteroidetes.Spirochaetes were higher in the regular group than in the irregular group at all 3 stages(P<0.05).Conclusion There were some differences in intestinal microbial composition between the two groups of macaques with regular and irregular menstrual cycles,which provided some reference for the study of intestinal bacteria and ovulation disorders.
