摘　　要：将柔嫩艾美耳球虫(E.tenella)石家庄、沧州、保定、唐山分离株感染14日龄罗曼蛋公雏,每个地区设立5个用药组、1个感染不用药对照组和1个不感染不用药对照组,以POAA、RLS、ROP、ACI作为评定指标对该虫株对氯羟吡啶、莫能菌素、地克珠利、妥曲珠利、磺胺喹噁啉5种常用抗球虫药的抗药性进行了综合评定,分析了该地区球虫的抗药性及用药对策。结果表明:E.tenella石家庄分离株对氯羟吡啶呈完全抗药性,对莫能菌素、妥曲珠利、磺胺喹噁啉呈重度抗药,对地克珠利表现轻度抗药;E.tenella沧州分离株对氯羟吡啶、莫能菌素、地克珠利呈完全抗药性,对妥曲珠利、磺胺喹噁啉呈中度抗药;E.tenella保定分离株对氯羟吡啶呈完全抗药性,对妥曲珠利呈重度抗药,对莫能菌素、地克珠利、磺胺喹噁啉呈中度抗药;E.tenella唐山分离株对莫能菌素、妥曲珠利呈完全抗药性,对氯羟吡啶、地克珠利呈中度抗药,对磺胺喹噁啉呈轻度抗药。Infection E.tenella of Shijiazhuang,Cangzhoa,Baoding and Tangshan strains drenched to the 14d male chicks, Each region set up 5 drug group, one infected without medication control group and one infected drug control group.Comprehensive assessment anticoccidial drug resistanta about monensin, Diclazuril,toltrazuril and sulfonamide quinoline quinoxaline commonly used with POAA, RLS, ROP, ACI clopidol as an evaluation index, analysis of the coccidia of this region of drug-resistant and drug countermeasures. The results show that：E.tenella Shijiazhuang isolate strains to chloride hydroxide pyridine is completely drug resis- tant, serious resistant Of monensin, toltrazuril, sulfaquinoxaline and on diclazuril performance light resistant;E. tenella Cangzhou isolates was completely resistant with clopidol,monensin,diclazuril and middle resistant to tohrazuril sulfaquinoxaline;E.tenella Baoding separation strains to chloride hydroxide pyridine is completely drug resistant, serious resistant Of tohrazuril, and on diclazuril monensin,sulfaquinoxaline performance middle resistant; E.tenella Tangshan isolate strains was completely resistant with monensin, tohrazuril and middle resistant to clopidol, Diclazuril, Was light resistant sulfaquinoxaline.
