摘 要：
奥斯特线虫病是一种严重危害绵羊和牛的寄生虫病。该病多呈现隐形感染,根据临床症状很难诊断,多数圆线虫虫卵形态相似,通过粪便虫卵检测仅能够初步诊断该病。笔者通过饱和蔗糖水漂浮法优化奥斯特线虫虫卵检测方法,虫卵检出率100%,单次虫卵的检出数量为30个左右;收集奥斯特线虫虫卵,研究其虫卵形态和体外发育情况,根据幼虫形态准确诊断奥斯特线虫病,为该病的生前诊断提供技术支持。

摘 要：
Ostertagia ostertaigi is a serious parasitic disease of sheep and cattle. The disease is difficult to diagnose according to the clinical symptoms. Most strongylodes eggs have similar morphology,and the disease can be preliminarily diagnosed by fecal egg detection. The author optimized the detection method of Ostertagia ostertaigi'eggs by saturated sucrose water float method,the detection rate of eggs was 100% and the number of eggs detected in a single each time was about 30. Ostertagia ostertaigi'eggs were collected to study their in vitro development,and accurate diagnosis of Ostertagia ostertaigi was made according to the morphology of larvae,providing technical support for prenatal diagnosis of the disease.
