【摘要】 采用离心沉淀法、卢戈氏碘液染色法、饱和蔗糖溶液漂浮法和麦克马斯计数法对采自河南省西峡县和陕西省富平、麟游、泾阳、高陵县共316份奶山羊新鲜粪便样品进行检查,结果表明,共发现11种(类)寄生虫,寄生虫总感染率高达98.1%(310/316),优势虫种为球虫、阿米巴以及圆线虫,其中以球虫感染率最高,达88.6%(280/316),最高OPG达56 000;阿米巴和圆线虫的感染率分别为65.5%和37.7%,圆线虫最高EPG达7 000;隐孢子虫、贾第虫、鞭虫、细颈线虫、肺线虫、莫尼茨绦虫、矛形双腔吸虫、蛲虫的感染率分别为0.3%、0.9%、3.2%、0.3%、4.1%、4.1%、1.3%、0.3%;75.0%的阳性样品为2~4种寄生虫混合感染,且以2种寄生虫混合感染率最高,高达47.2%;舍饲和放牧奶山羊的寄生虫感染率分别为98.6%和97.1%。可见,我国奶山羊的肠道寄生虫感染较为普遍。更多还原

【Abstract】 316 fecal samples collected from Xixia in Henan province,and Fuping,Linyou,Jingyang,Gaoling in Shaanxi province were examined for the presence of oocysts or eggs using the centrifugation method,the Lugol’s iodine-solution staining method,the Sheather’s sugar flotation technique and Mc Master’method. The results showed that eleven intestinal parasite species were discovered and the overall infection rate was 98. 1%. The dominant species were Coccidian,Strongylus spp and Entamoeba. The Coccidian was found with the highest infection rate of 88. 6%,and the highest OPG was 56 000. In contrast,the infection rate of Entamoeba and Strongylus spp was 65. 5% and 37. 7%,respectively. And the highest EPG of Strongylus spp was 7 000. On the other hand,the infection rate of Cryptosporidium,Giardia,Trichuris,Nematodirus,Parafilaroides decorus,Moniezia,Dicrocoelium dendriticum and Enterobius was 0. 3%,0. 9%,3. 2%,0. 3%,4. 1%,4. 1%,1. 3%,0. 3%,respectively. We also found the result that 75. 0%positive samples were mixed infected by 2—4 kinds of parasites. However the mixed infection rate of two kinds of parasites was the highest,as high as 47. 2%. The infection rate of parasites was 98. 6% and97. 1% in drylot feeding goats and grazing goats,respectively. Our report indicates that the intestinal parasitic infection of dairy goats is much common in China and the comprehensive preventing and control on the intestinal parasites of dairy goats should be strengthened.更多还原
