For determination whether strangles has invaded the Hidaka district of Hokkaido, the main racehorse-breeding area of Japan, a epizootiological survey with bacterial isolation was carried out during the breeding season in 1995. Streptococcus equi subsp. equi, which is the causative agent of strangles, was isolated from two Thoroughbred horses with submandibular lymphadenitis. Isolates were identified by serological grouping, biochemical tests and analysis of cell surface proteins by Western immunoblotting. Through this survey, it revealed that S. equi subsp. equi has invaded the Hidaka district and that strangles has become prevalent in racehorse-breeding farms in this area.
为确定马腺疫是否已侵入日本主要的赛马养殖区北海道日高地区，于1995年繁殖季节期间开展了一项伴有细菌分离的流行病学调查。从两匹患有颌下淋巴结炎的纯种马中分离出了马腺疫的病原体马链球菌马亚种。通过血清学分型、生化试验以及蛋白质印迹法对细胞表面蛋白进行分析来鉴定分离株。通过本次调查发现，马链球菌马亚种已侵入日高地区，且马腺疫在该地区的赛马养殖场中已变得普遍。
