摘要: 为初步了解山西榆次区放养绵羊消化道线虫的感染状况,采用蠕虫学剖检术对榆次区北郊农村的4只绵羊消化道线虫感染率和感染强度进行了初步研究。结果显示,榆次区北郊放养绵羊消化道线虫总感染率为100%(4/4),共检出7种线虫,分别为:捻转血矛线虫感染率为100%,平均感染强度51条;环纹奥斯特线虫为100%,39条;羊仰口线虫为50%,5条;长刺似细颈线虫为100%,29条;哥伦比亚食道口线虫为50%,4条;绵羊毛尾线虫为100%,12条;绵羊夏伯特线虫为100%,81条。经t检验,真胃中捻转血矛线虫与环纹奥斯特线虫两虫种感染强度差异不显著;小肠中羊仰口线虫与长刺似细颈线虫和大肠中绵羊毛尾线虫与哥伦比亚食道口线虫、绵羊夏伯特线虫虫种感染强度差异显著。同时,对长刺似细颈线虫进行了形态再描述。

Abstract: In order to understand the infection status of digestive tract nematodes in free ranging sheep in Yuci District of Shanxi Province, the infection rate and infection intensity of gastrointestinal nematodes in four sheep in the northern suburb of Yuci District were studied by using complete helminthological dissection. The results showed that the total infection rate of digestive tract nematodes of the four sheep was 100% (4/4), and a total of 7 kinds of nematodes were detected. The observed nematodes species and their corresponding infection rate and average infection intensity were as followed: Haemonchus contortus (100%, 51), Ostertagia circumcincta (100%, 39), Bunostomum trigonocephalum (50%, 5), Nematodirella longispiculata (100%, 29), Oesophagostomum columbianum (50%, 4), Trichuris ovis (100%, 12), and Chabertia ovina (100%, 81). The t-test showed that there was no significant difference in infection intensity between Haemonchus contortus and Ostertagia circumcincta in abomasum; in the small intestine, the significant difference in infection intensity between Bunostomum trigonocephalum and Nematodirella longispiculata was observed; in the large intestine, there was significant difference in infection intensity between Trichuris ovis and Oesophagostomum columbianum, Chabertia ovina. Furthermore, the isolates of Nematodirella longispiculata were morphologically redescribed.
