摘要
应用石歧杂肉仔鸡，检测了采自我国山东聊城的４种艾美耳球虫对６种常用抗球虫药的敏感性。根据最适抗球虫活性百分率、相对卵囊产量和病变记分减少率３项指标综合判定，山东聊城地区的柔嫩艾美耳球虫、堆型艾美耳球虫、巨型艾美耳球虫和布氏艾美耳球虫的４种球虫混合感染对盐霉素Ｓａｌｉｎｏｍｙｃｉｎ（赛可喜Ｓａｃｏｘ）、拉沙里菌素Ｌａｓａｌｏｃｉｄ（球安Ａｖａｔｅｃ）、莫能霉素Ｍｏｎｅｎｓｉｎ（欲可胖Ｅｌａｎｃｏｂａｎ）、马杜拉霉素Ｍａｄｕｒａｍｉｃｉｎ（抗球王ＫＱＷ）和常山酮Ｈａｌｏｆｕｇｉｎｏｎｅ（速丹Ｓｔｅｎｏｒａｌ）均存在不同程度的抗药性，其中对抗球王和欲可胖有重度抗药性，对球安、速丹和赛可喜具有中度抗药性。４种艾美耳球虫混合感染对氯嗪苯乙氰Ｄｉｃｌａｚｕｒｉｌ（伏球Ｃｌｉｎａｃｏｘ）无抗药性。尽管４种艾美耳球虫混合感染对赛可喜具有中等程度的抗药性，在增重方面却优于伏球。
The sensitivity of four mixed species of Eimeria tenella,E.acervulina,E.maxima,and E.brunetti from Liaocheng,Shandong Province in China to 6 common used cocidiostats was investigated in broilers.Based on the criteria of percent of optimum anticoccidial activity(POAA),relative oocyst procuction (ROP) and reduction of small intestinal and cecal lesion scores(RLS),the experment revealed that the four species were high resistant to Monensin(Elancoban),Maduramicin (KQW),medium resistant to Lasalocid(Avatec),Salinomycin(Sacox),Halofuginone(Stenoral),and not resistant to Diclazuril(Clinacox).However,Sacox had better weight gain than Clinacox.
