Proc Natl Acad Sci U S A 111: E2329-2338 The majority of microbiome studies require that samples be taken at specific facilities by trained personnel, increasing costs and excluding some subjects from participation. The authors developed a protocol for self-collection of stool and saliva samples, and frozen shipping within 24 hours of collection. They used metagenome and metatranscriptome analysis to assess the accuracy and feasibility of this protocol against 2 other sample handling methods. There was strong within-subject correlation between all 3 methods at gene, species, and transcript levels, indicating that the developed protocol had minimal effect on metagenomic profiles. Oral microbes co-occurring in stool samples displayed a drop in abundance and transcript levels, suggesting that oral microbes that transit into the gut are not stable and do not play a role in gut ecology. Overall, the study provides a robust method for self-collection and distinguishes relationships between metatranscriptomes and metagenomes, highlighting the complementarity of both approaches in microbiome studies.
