摘要: 应用饱和蔗糖溶液漂浮法对河南、山东和东北等地的1052只绵羊球虫感染情况及种类进行了调查,结果表明球虫总感染率为94.8%,对968份阳性样本中的球虫卵囊进行形态学鉴定,共检出12种艾美耳球虫,分别为阿撒他艾美耳球虫、巴库艾美耳球虫、小型艾美耳球虫、贡氏艾美耳球虫、类绵羊艾美耳球虫、颗粒艾美耳球虫、苍白艾美耳球虫、马耳西卡艾美耳球虫、温布里吉艾美耳球虫、错乱艾美耳球虫、槌形艾美耳球虫和浮氏艾美耳球虫。调查结果发现绵羊最多可同时感染9种球虫,多数为2~5种,混合感染率为71.8%;1岁以下和1岁以上绵羊球虫感染率分别为99.4%和86.0%,平均OPG值分别为7907.36和3263.89;舍饲和放牧绵羊球虫感染率分别为97.0%和89.0%;夏、秋季为球虫主要流行季节。

Abstract: To understand the prevalence and infection speices of coccidia, a total of 1052 sheep from Henan, Shandong and Northeast China were investigated by using the Sheather’s sugar flotation method. The average infection rate of coccidia was 94.8%. Coccidium oocysts contained in 968 positive samples were conducted morphological identification, and 12 species of Eimeria were detected, including E.ahsata, E.bakuensis, E.parva, E.gonzalezi, E.ovinoidalis, E.granulosa, E.pallida, E.marsica, E.weybridgensis, E.intricata, E.crandallis and E.faurei. The infection rate of mixed species were 71.8% and 2 to 5 mixed species were the most common, however, the maximum number of mixed species reached to 9. The infection rate was 99.4% and 86.0% in less than one-year-old sheep and more than one-year-old sheep, respectively. The average number of oocyst per gramme feces (OPG) was 7907.36 and 3263.89 in the two age groups, respectively. The infection rate of coccidia was 97.0% and 89.0% in drylot feeding sheep and grazing sheep, respectively. Summer and autumn were the two major seasons for coccidia prevalence in sheep.
