为了解安徽省望江县江滩放牧牛寄生蠕虫的感染情况，本研究采用饱和盐水漂浮法、沉淀法、贝尔曼法对此地区的115头放牧牛的新鲜粪便进行检查，同时对虫种感染率以及不同品种、性别、年龄牛感染率进行了统计分析。调查结果显示，当地放牧牛感染的蠕虫有夏伯特线虫、捻转血矛线虫、奥斯特线虫、肝片吸虫以及肺线虫，总感染率达到90.4%（104/115）。其中捻转血矛线虫为感染优势虫种，感染率达70.4%；捻转血矛线虫、夏伯特线虫在雄牛和雌牛中感染率的差异具有显著性统计学意义。调查结果对长江流域江滩放牧牛蠕虫病防治工作以及了解蠕虫与宿主的相互关系具有一定参考意义。

The prevalence of helminth infection was investigated in cattle on the beach of Yangtze River in Wangjiang county, Anhui Province. A total of 115 fresh fecal samples from yellow cattle and buffalos were examined using saturated salt solution flotation, precipitation and Baermann method, respectively. The prevalence of worm species in different hosts, genders and ages were compared. The results showed that 104 out of 115 (90.4%) cattle were infected with Chabert sp., Haemonchus contortus, Ostertagia sp., Fasciola sp. and Pulmonarynematode. The dominant parasite was H.contortus with a prevalence of 70.4%. The prevalences of H.contortus and Chabert sp. were 82.5%and 70.0%in male cattle, which were significantly higher than that (51.1%and 36.2%) in females. The results of this investigation provided a basis for control of helminth infection in cattle on the beach of Yangtze River and better understanding of the parasite-host relationship of H.contortus and Chabert sp.
