Dysbiosis of host-associated commensal microbiota is emerging as an important factor in risk and phenotype of immunologic, metabolic, and behavioral diseases. Accurate analysis of microbial composition and functional state in humans or mice requires appropriate collection and pre-processing of biospecimens. Methods to sample luminal and mucosal microbiota from human or mouse intestines and to profile microbial phylogenetic composition using 16S rRNA sequencing are presented here. Data generated using the methods in this unit can be used for downstream quantitative analysis of microbial ecology.
宿主相关共生微生物群的失调正成为免疫、代谢和行为疾病风险及表型的一个重要因素。准确分析人类或小鼠体内的微生物组成和功能状态需要对生物样本进行适当的采集和预处理。本文介绍了从人类或小鼠肠道中采集管腔和黏膜微生物群以及使用16S rRNA测序分析微生物系统发育组成的方法。使用本单元所述方法生成的数据可用于微生物生态学的下游定量分析。
