鼻蛭寄生特异性的比较分析

Comparing Analysis of Parasitic Specificity of Nasal Leech(Dinobdella ferox)

通过对云南省鼻蛭(D inobdella ferox)分布概况的调查和标本采集,初步探明鼻蛭在昆明、楚雄、红河、思茅、西双版纳地区均有分布.实验室内用鼻蛭幼体分别对家兔、大白鼠、家鸽、牛蛙进行感染实验,结果表明:鸟类、两栖类不是鼻蛭的寄主,即使人为地进行感染,鼻蛭也不能正常生长;鼻蛭仅以哺乳动物为寄主,寄生于寄主鼻、咽腔内的鼻蛭生长迅速且呈递增趋势,在感染一个月内,蛭体重增加可达200余倍.鼻蛭的寄生会对其寄主造成严重危害,应加强对鼻蛭危害的重视,并对其分布、生活史及防治开展综合研究.

We investigated the nasal leech （Dinobdella ferox） in Yunnan province. The leech widely distributes in Yunnan. From Kunming, Chuxiong, Honghe, Simao and Xishuangbanna we got the samples of larvae and adult Dinobdella. The infraction experiment of larvae Dinobdella to rabbit, albino rat, pigeon and bullfrog shows that neither ayes nor amphibian is the host of the nasal leech. The larvae nasal leeches can easily move into mammals＇ nose and attach themselves to the mucous membranes of the parasitifer, and their weight can grow as high as 200 times within 1 month. The parasitification of this kind of leech couses bleeding or fatal obstruction.
