Outline of Final Research Achievements

In this study, we performed comparative genomic analysis of Campylobacter jejuni from wild birds that exhibited genomic and phenotypic alteration through colonization in chicken intestine. The in silico pathway analysis predicted the functional network of the motility-associated genes that were altered throuogh the chicken passage. Human clinical strains were also subjected to the similar pathway analysis and bacterial sugar biosynthesis/transport networks were predicted.

Academic Significance and Societal Importance of the Research Achievements

野鳥がカンピロバクターを高率に保菌することは以前より認知されていたが、本研究の遂行を通じ、一部の株は鶏腸管定着を果たした上で、ヒト健康被害を招き得ることがゲノムの揺らぎを通じて確認された。関連遺伝子群の探知ならびに機能性探索は、今後の本菌感染に係る予防疫学の充実を図る上で重要な事項となるものと思われる。また、ヒト感染を通じた当該菌のゲノム・形質変動は、未だ明確に定義がなされていない、ヒトにおける病態発現機構を探知するにあたっても重要な知見となるものと考えられ、同菌の病原性亢進に資すると思われる候補遺伝子の抽出は、本菌感染危害の早期探知に向けた標的分子としての活用も期待される。
