驯养中缅树鼩的消化道寄生虫监测及寄生蠕虫驱虫效果

目的了解野外树鼩和驯养树鼩寄生虫感染情况及其驱虫效果。方法 随机选取野外捕获3 d和已驯1个月(未驱虫)、F1代、F2代、F3代树鼩,各五笼,每笼3～4只,用饱和食盐水漂浮法检查粪样虫卵或卵囊,根据形态学鉴定虫种。结果粪样共检获两种寄生性线虫虫卵(毛尾线虫和奇口线虫)、膜壳绦虫卵、一种球虫卵囊。野外捕获3 d和驯养1个月树鼩的线虫卵检出率最高,达100%;绦虫卵检出率分别达60%和20%;球虫卵囊检出率分别达40%和20%。驯养F1代、F2代、F3代树鼩,仅F2代1笼检出线虫卵,检出率为20%。驱虫当天粪样检出的线虫虫卵、绦虫卵和球虫卵囊与驱虫前检出结果比例一致,并收集到39条奇口线虫、3条毛尾线虫、18条长膜壳绦虫。驱虫后第2天和第3天均未收集到虫体,粪样中也未检测到线虫卵和绦虫卵,仅检测到球虫卵囊。结论为树鼩实验动物化的消化道寄生虫病的监测和控制提供基础信息。

Dectection of parasitic infection in domesticatedtree shrew and the determination of de-wormingeffect by examining the fecal samples

Objective The aim of the present study was to investigate the infection and parasite-expelling effect on wild and domesticated tree shrews,respectively.Methods The wild tree shrews randomly captured three days before the tests,domesticated ones reared for a month,and the F1,F2 and F3 generation were included in this study.Either the wild or the domestic tree threws were divided into 5 cages(3-4 animals in each cage).The examination of fecal parasitic ova or oocysts was carried out using saturated sodium chl...
