一起藏北绵羊奥斯特线虫病的诊治

Diagnosis and Treatment of Oyster Nematode Disease on Northern Tibetan Sheep

消化道线虫是危害藏北绵羊的主要寄生虫,日常的饲养管理过程中需不定期驱虫,否则可能引起寄生虫病的发生。西藏安多县强玛镇某牧户饲养藏北绵羊148只,2021年6月中旬开始陆续发病,至7月下旬,共死亡42只,经剖检及实验室检查,确诊为奥斯特线虫感染。对所有羊只的粪便用虫卵饱和蔗糖水漂浮法进行镜检,虫卵的检出率达100%,单次虫卵的检出数量为45个左右。所有藏北绵羊经灌服阿苯达唑片治疗,一周后痊愈。本病例为藏北绵羊奥斯特线虫病防控提供了重要参考。

The digestive tract nematode is the main parasitic disease that harms sheep in northern Tibet.It needs to be treated irregularly in the daily feeding and management process,otherwise,it may cause such diseases.A herdsman in Qiangma Town,Anduo County,Tibet,raised 148 northern Tibetan sheep,which began to get sick in the middle of June 2021.By the end of July,42 sheep had died.After autopsy and laboratory examination,it was confirmed that the sheep were infected with Oyster nematode.The feces of all sheep were examined under microscope with egg saturated sucrose water floating method.The detection rate of eggs reached 100%,and the number of eggs detected at a single time was about 45.All northern Tibetan sheep were cured after taking albendazole tablets by gavage for one week.This case provides an important reference for the prevention and control of Oyster nematode disease in northern Tibet sheep.
