Forensic analysis of the microbiome of phones and shoes

In this study, 2 participants sampled the front and back of their cell phones, four different locations on the soles of their shoes, and the floor beneath them every waking hour over a 2 day period. A further 89 participants took individual samples of their shoes and phones at three different scientific conferences. Due to FigShare’s limit on file size, the read file and index file were split into 102 and 23 files respectively. They can be concatenated using the “cat” command in Unix before passing to split libraries in QIIME. The OTU table (rarified to 1000 reads per sample) and mapping file used in the study are also provided. Requests for further data or information should be sent to Simon Lax at [e-mail]

本研究中，2名受试者在为期2天的清醒时段内，每小时采集一次其手机正反面、鞋底4个不同部位以及脚下地面的样本。另有89名受试者在三场不同的学术会议上分别采集了各自鞋子与手机的样本。由于FigShare平台的文件大小限制，测序读长文件（read file）与索引文件（index file）分别被拆分为102个与23个文件。可通过Unix系统中的`cat`命令将其拼接，再导入QIIME的拆分文库流程。本研究中使用的操作分类单元（Operational Taxonomic Unit, OTU）表（经稀疏化处理至每个样本1000条读长）与映射文件亦一并提供。如需获取更多数据或相关信息，请联系Simon Lax，邮箱：[e-mail]。
