河南及重庆、安徽部分地区山羊球虫感染情况与种类调查

采用饱和蔗糖溶液漂浮法对河南省的8个地区、重庆市的云阳县和安徽省的合肥市共1126份山羊粪便样品进行检查，发现1070份球虫阳性样品，总感染率95．03％。对813份阳性样本中的球虫卵囊进行形态学鉴定，共发现12种艾美耳球虫，分别为阿普艾美耳球虫、阿氏艾美耳球虫、艾丽艾美耳球虫、斑点艾美耳球虫、苍白艾美耳球虫、家山羊艾美耳球虫、柯察艾美耳球虫、克氏艾美耳球虫、妮氏艾美耳球虫、山羊艾美耳球虫、羊艾美耳球虫和约奇艾美耳球虫。山羊最多可同时感染9种球虫，多数为2-4种，混合感染率78．7％；6月龄以下、6-12月龄和1岁以上山羊球虫感染率分别为93．3％、97．1％和96-3％，平均OPG值分别为5282．77、3550．71和1507．88；除奶山羊外，不同品种山羊球虫感染无明显差异；舍饲和放牧山羊球虫感染率分别为95．7％和92．8％，平均OPC值分别为3744．35和1028．62。跟踪调查显示，舍饲山羊球虫感染无明显季节性，但夏秋季节球虫感染强度高于冬春季节。

Investigation on Coccidia Prevalence and Species in Goats in Partial Areas of China

1 126 goat fecal samples from eight areas in Henan, Yuyang in Chongqing and Hefei in Anhui were collected andexamined using the Sheather＇s sugar float technique. A total of 1 070 samples were positive, with the overall prevalence of 95.03%. Coccidia oocysts in 813 positive samples were measured and 12 Eimeria species were detected, including E.ap- sheronica, E. arloingi, E.alijevi, E.punctata, E.pallida, E.hirci, E.kocharli, E.christenseni, E.ninakohlyakimovae, E.cap- rina, E.caprovina and E.jolchijevi. 2-4 species of mixed infections were common in goats, with the most number of mixed infection reaching to nine. The rate of mixed infection was 78.7%. The infection rates were 93.3%, 97.1% and 96.3% in lessthan 6-month-old, 6-12-month-old and more than 1-year-old goats, respectively. No significant difference was observed in different goats except for dairy goat. The average infection rates were respectively 95.7% and 92.8% in drylot feedinggoats and grazing goats, with the value of OPG being 3 744.35 and 1 028.62, respectively. Tracking survey showed that the seasonal differences of Coccidia infection were not significant in drylot feeding goats;however, the infection intensity in sum- mer and autumn was higher than that in winter and spring.
