Research Abstract

ブリ属魚類養殖場における新型および旧型レンサ球菌感染症の疫学的研究を行った。旧型レンサ球菌(Lactococcus garvieae)の薬剤感受性を調査すると共にファージ型を明らかにし、近年の旧型レンサ球菌に新しい遺伝型が増加していること明らかにした。また、L. garvieaeは、養殖魚以外に多くの宿主から分離されており、それらの細菌と遺伝型、ファージ型、ブリに対する病原性が異なることを示した。ブリ属養殖魚類由来の新型レンサ球菌(Streptococcus dysgalactiae)は、畜産動物由来のS. dysgalactiaeとその遺伝型が異なると共に、SodA遺伝子に違いが認められ、その違いを基に両者を識別できるプライマーを設計した。このプライマーで、PCRで容易に両者を識別できることが可能となった。
