柯氏鼠兔胃肠道线虫的调查

Investigation of nematodes in gastrointestinal tract of Ochotona koslowi

2007年10～11月，应用蠕虫学完全剖解法对13只柯氏鼠兔进行了寄生虫检查。结果显示，柯氏鼠兔感染的线虫有四川曲殖线虫、Ohbayashinema erbaevae和Eugenurissp．，其感染率分别为46．14％、38．50％和7．60％；平均感染强度为33．33、5．80和1．00。柯氏鼠兔是这些线虫的新宿主，而Ohbayashine—maerbaevae线虫为中国新记录。四川曲殖线虫是Graphidiella olsoni线虫的同种异名。

From October to November of 2007,13 Ochotona teoslowi were examined for the presence of parasitic helminthes by a helminthological approach. The results showed that O. koslowi were infected with nematodes Graphidiella szechuanensis ,Ohbayashinerna erbaevae and Eugenuris sp. , and the infection rates were 46.14%,38. 50% and 7. 60%, respectively. The average infection intensities were 33. 33,5. 80 and 1.00 ,respectively. O. kosloze.i was the new host of these parasitic nematodes along with Ohbayashinerna er- baevae recorded the first time in China. G. szechuanensis was the synonym of Graphidiella olsoni.
