摘要
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。
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 chloride flotation method,and then the species of the parasites were identificated by their shaps.Results This experiment resulted in 2 species of parasitic wireworm eggs,that is Trichocephalus and Rictularia sp.,Hymenolepis diminuta eggs,and a kind of coccidian oocysts.Among the animals wildly captured and those domastically reared for one month,the infection rate of parasitic wireworm both reached 100%,with 100% and 80% of serious infestative rates,60% and 20% of cestode eggs,40% and 20% of coccidia oocyst eggs,respectively.By contrast,parasitic wireworm eggs infected only 20% of the F1 generation and disappeared in the F2 or F3 generation.These results were consistent with those obtained immediately after the first expelling of the parasites.39 Rictularia sp.,3 Trichocephalus and 18 Hymenolepis diminuta were collected on the first expelling day.Except coccidia oocyst eggs,no parasites such as nematode eggs or cestode eggs were detected on the following two days in the fecal samples from the animals.Conclusions The results of present study provide elementary information for the detection and control of gastrointestinal parasite infection in the tree threws.
