Outline of Final Research Achievements

To rapidly and simply detect Campylobacter jejuni serogroup O (HS:19) with a high risk of inducing Guillain-Barre syndrome (GBS), we newly generated a monoclonal antibody (designated CampyGBS-Mab13) against this bacterium and developed a sandwich enzyme-linked immunosorbent assay using the monoclonal antibody as a capture and labeling antibody. The assay could detect not only Campylobacter jejuni serogroup O (HS:19) but also C. jejuni strains, considered to have a high risk of inducing GBS, of B, I, and R serogroups carrying the genes (cgtA, cgtB, and cst-II) required for ganglioside-like LOS synthesis.

Academic Significance and Societal Importance of the Research Achievements

本研究では、重篤な健康被害であるGBSを起こすリスクの高いC. jejuniを検出可能なモノクローナル抗体およびサンドイッチELISA法を開発した。GBS誘発リスクの高いC. jejuniについては、いまだ自然界での分布状況など不明な点が多く、本研究で開発したサンドイッチELISA法は、簡便かつ多検体を処理することが可能であることから、本菌のGBS誘発リスクの評価を行うのに有用であると考えられた。
