唐山市野生动物园21种动物肠道寄生虫感染情况的调查

Investigation on the intestinal parasite infection in 21 species of animals in the wildlife park in Tangshan city

目的了解唐山市某野生动物园圈养野生动物的肠道寄生虫感染情况。方法采用粪便检查的方法共检查21种动物的102份粪便样品,使用碘液染色法、饱和盐水浮聚法和生理盐水涂片法检测各种肠道寄生虫的感染情况。结果共检出12种寄生虫,总阳性率为57.8%,其中蛔虫感染最高,感染率达39.2%;其余为圆线虫、钩虫、鞭虫、原虫、吸虫,感染率分别为2.9%、4.9%、1.0%、5.9%和3.9%。结论唐山市某野生动物园圈养动物的肠道寄生虫感染率高,对人群具有感染人兽共患寄生虫的潜在危害。

Objective To investigate the infection status of intestinal parasite infection in animals in a wildlife park Tangshan city, Hebei province. Methods Fecal test was performed in 102 samples collected from 21 species of wild animals using iodine staining, brine-floatation and normal saline smear methods for detection of the intestinal parasite infections. Results A total of 12 species of parasites were detected in the 102 samples.The total positive rate was 57.8%, in which the most important infection was associated with Ascaris(39.2%), followed by Strongyloides stercoralis(2.9%), hookworm(4.9%), Trichuris(1.0%), protozoa(5.9%) and trematode(3.9%). Conclusion Intestinal parasites are relatively high in wild animals in the wildlife park in Tangshan city, which suggests that this infection status may lead to higher risks of zoonotic parasitic disease in local population.
