滇西亚种树鼩体外寄生虫自然感染状况及分析

目的调查滇西亚种树鼩体外寄生虫的自然感染状况,为建立树鼩质量控制标准提供依据。方法对野生的滇西亚种树鼩和自繁F1代树鼩各60只分别用尸检法和活体法检测,随即采用拔毛或用透明胶带粘取腋下、耳根、腹股沟、肛门附近等处的毛发制片,置于体视镜和显微镜下观察虫体和虫卵。结果野生滇西亚种树鼩和自繁F1代树鼩体外寄生虫自然感染率分别为：虱子25%/6%、蚤5%/0、蜱1.6%/0、水蛭1.6%/0、虱子和蚤混合感染1.6%/0。结论野生树鼩体外寄生虫的自然感染多为虱子和蚤,其次还有蝉、水蛭,总感染率明显高于自繁F1代。使用灭虱灵对于驱除树鼩体外寄生虫具有较好的疗效。

A Survey on the Epizoic Parasites Infection in Tupaia Belangeri Chinensis

Objective To investigate the epizoic parasites infection in tree shrew（tupaia belangeri chinensis）,and to provide a basis for seting up the quality standard of tree shrew.Methods Sixty wild tree shrews were executed by dislocation,and took hair to production from oxter、ear、groin、round anus of wild tree shrews and F1 generation tree shrews,then detected the epizoic parasites under platoscope and microscope.Results The natural infectious rate of the epizoic parasites in wild tree shrew and F1 generation tree shrews were respectively louse（25% /6%）、flea（5% /0）、cicadas（1.6% /0）、bloodsucker（1.6% /0）、infection with louse and flea（1.6% /0）.Conclusions The most of epizoic parasites identified in tree shrews were louse and fleas,secondly were cicadas and bloodsucker.As a whole,infectious rate of the wild tree shrews was obvious more than F1 generation tree shrews,and we gained good effect by taking a preventing and treating measures.
