福州动物园圈养鸟类肠道寄生虫调查

为调查福州动物园圈养鸟类消化道寄生虫感染情况,采集16种禽类31份粪便样品,应用饱和盐水漂浮法和自然水洗沉淀法收集虫卵,麦克斯特计数法对采集的粪便样本进行虫卵测定。检查结果显示,寄生虫感染阳性样品数有23份,占样品总数的74%。总共检出6种寄生虫感染,按感染例数从大到小排序为:球虫(9例)、吸虫(7例)、绦虫(6例)、线虫(5例)、鞭虫(4例)、纤毛虫(3例)。感染寄生虫的禽类中,孔雀的感染强度最高,EPG为9 150个/g;其次是巨嘴鸟,EPG为4 500个/g;第三是东方白鹳,EPG为3 300个/g。其他鸟类的EPG分布在0~2 100个/g。该调查结果为福州动物园圈养鸟类寄生虫病的防治以及制定科学的驱虫程序提供可靠的依据。

Investigation of intestinal parasite infection in captive birds in the Fuzhou zoo

To investigate the situation of intestinal parasite infection in captive birds in the Fuzhou zoo, 31 fecal samples from 16 kinds of birds were collected and ovum in feces were obtained by using saturated salt water float and natural water precipitation, para-site species and infection intensity (EPG) were confirmed by McMaster method. The results showeds that 23 of 31 fecal samples were positive of intestinal parasite infection, the positive rate was 74% and 6 kinds of parasite infections were determined. They were coc-cidial infection (9 cases), trematode infection(7 casas), tapeworm infection (6 cases), nematode infection (5 cases), whipworm infection (4 cases), and ciliate infection (3 cases). Among birds of parasitic infection, infection intensity was the strongest in peacock, EPG was 9 150/g;the second was in toucan, the EPG was 4 500/g;the third was in oriental stork, the EPG was 3 300/g. And the EPGs were about 0~2 100/g in the other birds. The results provide a scientific basis for prevention and treatment of parasite infection in captive-breed-ing birds in zoos.
