我国部分地区羊肠道寄生虫感染情况的调查

Investigation on Intestinal Parasite Infections in Sheep and Goats in Some Areas of China

为了解我国部分地区羊肠道寄生虫的感染情况,采用离心沉淀法、卢戈氏碘液染色法和饱和蔗糖漂浮法对我国6省(自治区)共935份羊粪便样品进行显微镜检测。结果显示,935份羊粪便样品中,寄生虫总感染率为83.9%(784/935),共检出7类寄生虫,分别为艾美耳球虫、阿米巴原虫、毛首线虫、类圆线虫、细颈线虫、莫尼茨绦虫和歧腔吸虫。其中优势感染种类为艾美耳球虫和阿米巴原虫,感染率分别为81.1%(758/935)和11.2%(105/935);其他肠道寄生虫毛首线虫、类圆线虫、细颈线虫、莫尼茨绦虫、歧腔吸虫的感染率分别为3.2%(30/935)、9.2%(86/935)、0.4%(4/935)、2.4%(22/935)和0.1%(1/935)。综上所述,我国羊肠道寄生虫感染情况普遍存在,影响了羊养殖业的健康发展,研究结果可为羊肠道寄生虫病的防控提供参考。

Microscopic examination of 935 sheep feces samples from six regions of Henan,Guizhou,Shaanxi,Liaoning,Inner Mongolia and Xinjiang was carried out by centrifugal sedimentation,Lugol's iodine staining and saturated sucrose solution floatation.The results showed:the total infection rate of intestinal parasites was 83.9%(784/935),7 intestinal parasites were found,they are Eimeria spp,Amoeba,Trichocephalus,Strongyle spp,Nematodirus spp,Moniezia and Dicrocoelium.The dominant ones are Eimeria spp,and Amoeba.The infection rates of Trichocephalus,Strongyle,Nematodirus,Moniezia,Dicrocoelium were 3.2%(30/935),9.2%(86/935),0.4%(4/935),2.4%(22/935),and 0.1%(1/935),respectively.In summary,intestinal parasite infections in sheep are widespread in China,affecting the healthy development of sheep breeding,results of the study provided some references for parasitic disease control in sheep.
