对建平县家兔球虫病流行病学的调查

Epidemiological Investigation of Rabbit Coccidiosis in Jianping County, Liaoning Province

该项研究表明:该地区家兔球虫病原体有7种艾美尔球虫,其中肠球虫6种,肝球虫1种.急性球虫病多由肠球虫引起;慢性球虫病多由肝球虫引起,虽死亡率较低,但严重影响增重。家兔最早感染期是30日龄,感染率约80%;45～90日龄感染率约93.6%～100%,幼兔因球虫病死亡季节高峰是7月雨季。因此在7月份对30～90日龄幼兔进行药物防治是降低幼兔死亡率的关键。

This study shows that there are 7 species of Eimeria stiedae in Jianping County,Liaoning Province,among which 6 are intestine species and one is liver species. Acute rabbit coccidiosis is mostly caused by intestine species,while chronic coccidiosis are mainly caused by liver species. The mortality of rabbit coccidiosis is low but the disease results in low weight gain.30 days old is the early infection age for rabbit and then the morbidity rate is about 80% while in 45 to 90 days old the morbidity will rise to 93.6～100%.The peak of mortality occurs in July rainy season. It is, therefore, impontant to prevent rabbit death by drugs as they age 39～90 days.
