野生动物园动物肠道寄生虫感染情况调查

Investigation on the Prevalence of Intestinal Parasites in Wild Animal Zoo

为了解四川某野生动物园动物肠道寄生虫感染情况,本试验采用离心沉淀法、卢戈氏碘液染色法、饱和蔗糖溶液漂浮法对40种野生动物及混居水禽共计180份粪便样本进行调查。寄生虫总感染率为74.4%,共发现8种寄生虫,其中球虫、阿米巴原虫、蛔虫、鞭虫、毛细线虫、圆线虫、绦虫和吸虫感染率分别为31.1%、19.4%、15.6%、10.6%、17.2%、20.6%、4.4%和1.7%。结果表明,某野生动物肠寄生虫感染较为普遍,应采取有效的综合防治措施,以保证野生动物的健康。

To understand the prevalence of intestinal parasites in a wild animal zoo,a total of 180 fecal samples from 40 species of wild animals and mixed feeding waterfowl were examined using centrifugation method,Lugol＇s iodine stain method,and the Sheather＇s sugar flotation technique.The overall infection rate of parasites was 74.4%.Eight species of parasites were detected,including Coccidia,Acanthamoebida spp.,Ascaridae spp.,Trichuridae spp.,Capillariidae spp.,Strongylidae spp.,Cestoidea spp.and Trematoda spp.,with the prevalence of 31.1%,19.4%,15.6%,10.6%,17.2%,20.6%,4.4%,and 1.7%,respectively.The present results suggested the parasite infections were serious in wild animals in this zoo.Thus,valid measurements should be taken to protect the health of animals.
