The microbiome influences health and homeostasis, as well as the immune system, and any significant change in this equilibrium (dysbiosis) triggers both acute and chronic health conditions. Microbiome research has surged, in part, due to advanced sequencing technologies enabling rapid, accurate, and cost-effective identification of the microbiome. A major prerequisite for stool sample collection to study the gut microbiome in longitudinal prospective studies requires standardized protocols that can be easily replicated. However, there are still significant bottlenecks to stool specimen collection that contribute to low patient retention rates in microbiome studies. These barriers are further exacerbated in solid organ transplant recipients where diarrhea is estimated to occur in up to half the patient population. We sought to test two relatively easy sample collection methods (fecal swab and wipes) and compare them to the more cumbersome \"gold\" standard collection method (scoop) using two different sequencing technologies (16S ribosomal RNA sequencing and shotgun metagenomics). Our comparison of the collection methods shows that both the swabs and the wipes are comparable to the scoop method in terms of bacterial abundance and diversity. The swabs, however, were closer in representation to the scoop and were easier to collect and process compared to the wipes. Potential contamination of the swab and the wipe samples by abundant skin commensals was low in our analysis. Comparison of the two sequencing technologies showed that they were complementary, and that 16S sequencing provided enough coverage to detect and differentiate between bacterial species identified in the collected samples. Our pilot study demonstrates that alternative collection methods for stool sampling are a viable option in clinical applications, such as organ transplant studies. The use of these methods may result in better patient retention recruitment rates in serial microbiome studies.</p>","PeriodicalId":49231,"journal":{"name":"Biopreservation and Biobanking","volume":" ","pages":"425-440"},"PeriodicalIF":1.6,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/bio.2020.0032","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38301133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from such an assessment are critical to verify if samples stored for extended durations remain \"fit for purpose\" or if there is need to reconsider the utility of samples stored beyond a certain timeframe. The Ontario Tumour Bank has been collecting samples since 2004, and assesses a random selection of frozen samples each year for RNA and DNA integrity as a part of ongoing quality control (QC) practices. This historical quality assessment data provide a unique opportunity to assess the impact of extended storage on nucleic acid integrity using replicate samples that remain in the bank in the present day as comparators. <b><i>Methods:</i></b> To examine the stability of fresh-frozen tumor tissue stored at cryogenic temperatures, RNA was extracted and analyzed from 87 cases over 14 disease sites stored long term in vapor-phase liquid nitrogen (LN2) (approximately -180°C).
