摘要： 应用离心沉淀法、卢戈氏碘液染色法、饱和蔗糖溶液漂浮法对采自河南省6个地市及吉林双辽、辽宁朝阳和山东东营共1109份绵羊粪便样品进行检查,结果发现9种(类)寄生虫,寄生虫总感染率为97.2%,以球虫感染率最高,达93.5%,卵囊数(OPG)最高值达652000;圆线虫和阿米巴感染率较高,分别为51.2%和71.3%,圆线虫卵数(EPG)最高值达69400;隐孢子虫、贾第虫、鞭虫、细颈线虫、莫尼茨绦虫和矛形双腔吸虫感染率分别为1.6%、5.7%、9.7%、0.3%、5.1%和2.6%;80.7%的绵羊阳性样品呈混合感染,最多可达5种。1岁以下和1岁以上绵羊寄生虫感染率分别为98.5%和87.5%;舍饲和放牧绵羊寄生虫感染率分别为97.5%和96.8%;寄生虫季节流行动态调查显示夏秋季节寄生虫感染率高于冬春季节。调查结果表明绵羊肠道寄生虫感染较为普遍,应加强其综合防控措施。

Abstract: A total of 1109 fresh fecal samples from six cities of Henan, Shuangliao of Jilin, Chaoyang of Liaoning and Dongying of Shandong were collected and examined the presence of oocysts or eggs using the centrifugation method, the Lugol’s iodine-solution staining method and the Sheather’s sugar flotation technique. Nine kinds of intestinal parasite species were discovered and the overall infection rate was 97.2%. Eimeria spp. was the most common parasite species, with the infection rate of 93.5% and the highest OPG reaching to 652000. The infection rates of Strongylus spp.and Entamoeba were 51.2% and 71.3%, respectively, and the highest EPG of Strongylus spp. was 69400. The infection rates of Cryptosporidium, Giardia, Trichuris, Nematodirus, Moniezia and Trematoda were 1.6%, 5.7%, 9.7%, 0.3%, 5.1% and 2.6%, respectively. 80.7% of positive samples were mixed infections, with the highest number of mixed-infections being five. The infection rate was 98.5% in no more than 1-year-old sheep and 87.5% in more than 1-year-old sheep, respectively. The infection rate of parasites was 97.5% in drylot feeding sheep and 96.8% in grazing sheep. Summer and autumn had a higher prevalence of parasites, compared to winter and spring. The present results showed intestinal parasites were commonly found in sheep. Thus, the general measures for the control and prevention were needed to strengthen.
