Project Period (FY) 2023-09-08 – 2026-03-31
Keywordsブルーリ潰瘍 / 比較ゲノム解析 / 感染伝播 / 西アフリカ
Outline of Annual Research Achievements

本疾患の起因菌は抗酸菌の一種Mycobacterium ulceransであるが、環境における感染源やヒトへの感染経路は全くわかっていない。本研究では、環境中に生息するM. ulceransの中でも病原性に関わる因子を有している菌のみヒトへの感染性を有するという新たな仮説を立て、環境および患者由来の菌(あるいは核酸)から病原因子の同定とその検証を行い、本感染症の感染経路の解明を目指す。
ガーナ国内におけるブルーリ潰瘍流行地域(デンス流域地区)の患者宅周辺の環境水等の検体採取を実施した。以前実施した調査と同様に起因菌M. ulceransが有するIS2404の検出がされ、起因菌が流行地域に定着していることが示唆された。ポータブルシーケンサーを現地に持ち込み16SrRNA配列のメタ解析を実施した。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

研究開始後早々に現地調査を実施し、環境検体の採集を実施できた。

Strategy for Future Research Activity

引き続き現地調査、環境検体の採集と起因菌の分離を進める

Causes of Carryover

研究開始時期が令和5年度途中の9月からとなったため、一部の経費を次年度の調査研究費用として使用する
