Abstract

The prevalence of Sarcocystis infection was examined in older cows and imported cattle slaughtered in East Hokkaido. Samples of myocardial tissues were examined for Sarcocystis microscopically. Sarcocystis cysts were detected in 15.7% of 83 older cows, 48.4% of 91 imported cattle which were kept in East Hokkaido prior to slaughter and 51.1% of 94 imported cattle slaughtered immediately after quarantine check. Based on the morphology of the cyst wall and the establishment of infection in experimentally inoculated dog, the Sarcocystis species was identified as Sarcocystis cruzi.

摘要

对在北海道东部屠宰的老龄奶牛和进口牛进行了肉孢子虫感染率调查。对心肌组织样本进行了肉孢子虫显微镜检查。在83头老龄奶牛中有15.7%检测到肉孢子虫囊肿，91头在北海道东部屠宰前饲养的进口牛中有48.4%检测到囊肿，94头检疫检查后立即屠宰的进口牛中有51.1%检测到囊肿。根据囊肿壁的形态以及在实验接种犬体内感染的确定情况，鉴定该肉孢子虫种类为克鲁斯肉孢子虫。
