Outline of Final Research Achievements

The purpose of this study was to develop technique to discriminate between bovine Eimeria spp. and diagnostic method for bovine coccidiosis. Ten Eimeria species, E. cylidrica、E. subspherica、E. wyomingensis、E. auburnensis、E. ellipsoidaris、E. zuernii、E. alabamensis、E. bovis、E. bukidnensis、E. canadensis were discriminated by newly developed nested multiplex PCR available for field samples .

Academic Significance and Societal Importance of the Research Achievements

牛のコクシジウム症はEimeria属原虫の感染に起因し、世界の畜産業に甚大な経済損失を与えている.その診断には糞便中オーシストの検出とその形態的種同定が求められる。しかし、検査には寄生虫学的熟練と時間を要し、新たな検査法の開発が望まれている。本研究では、牛寄生Eimeria10種を遺伝子領域のDNA塩基配列の違いで識別できることを明らかにし、 複数種の同時検出も可能なnested multiplex PCR法の開発に成功した。これにより、特別知識を要しないPCR検査法で牛のコクシジウム症を診断することが可能になった。
