大学研究室におけるヒト由来細菌の分布特性

摘要

本研究では，多数の人が集まる大学研究室における人由来細菌の環境中への拡散特性を把握することを目的として，ヒトの口腔内と手のほか，ドアノブ，机，PCのキーボード，空中の細菌のサンプリングを行い，NGSによる菌叢解析の結果を基に，その人由来細菌の環境中の拡散特性について検討した。本研究より得られた主な結果は下記に示す通りである。%Human-associated bacteria can cause mass infection. During infection period, the transmission route plays an important role. We are currently conducting a series of studies on the elucidation and control of mass infection mechanisms based on dynamic measurement of environment microbiomes. In this study, we investigated the influence of dispersion characteristics of oral microbial communities in occupied indoor environments. Hands, oral cavities, doorknobs, desk and keyboard surfaces, and air were sampled in a university laboratory. Oral bacteria Prevotella melaninogenica and Rothia mucilaginosa were detected from all samples with more than 3 order reads.
