野生太行猕猴肠道寄生虫感染的初步调查

A Preliminary Survey of Intestinal Parasites in Wild Macaca mulatta tcheliensis

为了解野生太行猕猴(Macaca mulatta tcheliensis)肠道寄生虫感染情况,采用饱和蔗糖溶液漂浮法、改良抗酸染色法和卢戈碘液染色法对194份粪便样品进行检查,结果共检查出阿米巴原虫(Amoeba sp.)、等孢球虫(Isospora sp.)、鞭虫(Trichuris sp.)、圆线虫(Strongylid sp.)、泡翼线虫(Physalopterasp.)、蛲虫(Enterobiussp.)、蛔虫(Ascaridsp.)7种寄生虫。寄生虫总感染率为97.4%,线虫感染率为93.8%。其中,鞭虫感染率最高,为91.2%;阿米巴原虫和圆线虫次之,分别为67.5%和60.8%。寄生虫混合感染率为87.1%;鞭虫、泡翼线虫、圆线虫3种线虫混合感染率为71%,同时感染其中2种的占42%,同时感染3种的占29%。对鞭虫卵、圆线虫卵和泡翼线虫卵进行感染强度测定,92%以上阳性样品线虫卵的EPG值在2000以下。等孢球虫为非人灵长类国内新发现种;所检出寄生虫中,阿米巴原虫、鞭虫、泡翼线虫、蛲虫、蛔虫均可感染人,因此具有重要的公共卫生意义。

In order to understand the intestinal parasite infection in wild Macaca mulatta tcheliensis, 194 fecal samples were collected and detected by the Sheather＇s sugar flotation, modified acid-fast staining and Lugol＇ s iodine-solution staining methods .The result showed that main intestinal parasites were Amoeba sp., lsospora sp., Trichuris sp., Strongylid sp. , Physaloptera sp., Enterobius sp. and Ascarid sp.. The total infection rate was 97.4%. The infection rate of nematode was 93.8%. The infection rate of Trichuris sp. was the highest （91.2%）. The infection rates of Amoeba sp. and Strongylid sp. followed with 67.5 % and 60.8 % , respectively. The mixed infection rate of parasites was 87.1%, that of nematode was 71%. The mixed infection of three nematodes （ Trichuris sp., Strongylid sp., Physaloptera sp.） was common, infected by two nematodes was 42%, by three nematodes was 29%. The infection intensities of the Trichuris, Strongylid, Physaloptera were detected by MacMaster＇ s method. EPG values of more than 92% of the nematode positive samples were below 2 000. The lsospora sp. was first reported in non-human primates in china; Amoeba, Trichuris, Physaloptera, Enterobius, Ascarid can infect human; therefore the results have an important significance to public health.
