Outline of Final Research Achievements

In 1991, enterotoxigenic Escherichia coli (ETEC) serotype O169:H41 was found in a foodborne outbreak. The strain possessed genes for three kinds of colonization factors and showed aggregative adhesion to intestinal epithelial cells in vitro with one novel colonization factor. The putative adhesins were purified and provided as antigens for the seroepidemiological investigation. Swine sera reacting with the antigen were prevalent unexpectedly; ETEC that has the novel colonization factor could be an etiological agent of zoonosis.

Academic Significance and Societal Importance of the Research Achievements

腸管毒素原性大腸菌(ETEC)はヒトのみならず、ウシやブタの下痢症原因菌でもあるが、それぞれの動物種にはそれぞれのETECがあり、ETECが種間を超えて人獣共通感染症をおこすことはないとされてきた。本研究は、ヒトのETECで最も検出頻度の高いO169がブタの腸上皮に付着するための遺伝子を保有し、ブタの多くがこの新規接着因子に対する抗体を血清中に保持していた。ETECには人獣共通感染症の原因になり得るものがあり、その対策をOne healthの概念の下で検討する必要があることが示された。
