西藏尼木县山羊蠕虫感染情况调查

Helminth Infections in Goats in Nimu County of Tibet

于2013年5月-2014年4月在西藏尼木县采用系统剖检法剖检99只山羊,并收集寄生虫虫体,依据形态学特征进行种类鉴定,并分析山羊感染情况。尼木县山羊蠕虫感染率为100%,均为混合感染。共鉴定寄生虫9科15属21种。胃肠道寄生线虫优势种为鞭虫属(36.4%),吸虫优势种为鹿同盘吸虫(60.6%)和后藤同盘吸虫(60.6%);绦虫/绦虫蚴优势种为细颈囊尾蚴(52.5%);门静脉系统主要寄生土耳其斯坦东毕吸虫(69.7%)。

Postmortem examinations were made in 99 goats in Nimu County of Tibe, and parasites were collected and identified based on morphology. The collected parasites were categorized, and infection status was analyzed. The helminth infection rate was 100% among the goats, and all showed a pattern of mixed infection. The identified parasites belonged to 21 species, 15 genera, and 9 families. The Trichuris genus（36.4%） was the most prevailing among nematodes in the gastrointestinal tract; Paramphistomum cervi（60.6%） and Paramphistomum gotoi（60.6%） were predominant among trematodes detected; Cysticercus tenuicollis（52.5%） was the predominant cestode detected; and Orientobilharzia turkestanicum was the major parasite detected in the portal vein（69.7%）.
