摘要
[目的]探讨堆型艾美耳球虫早熟株和母株对常用抗球虫药的敏感性。[方法]选用地克珠利、氯苯胍、二硝托胺、癸氧喹酯、尼卡巴嗪、马杜米星、盐霉素和拉沙洛西8种抗球虫药,进行鸡体试验,通过抗球虫活性百分比(POAA)、病变记分减少率(RLS)、相对卵囊产量(ROP)和抗球虫指数(ACI)4项指标进行综合评定。[结果]堆型艾美耳球虫早熟株和母株均对地克珠利、氯苯胍、癸氧喹酯、尼卡巴嗪、马杜米星和拉沙洛西敏感,对盐霉素轻度敏感,对二硝托胺不敏感。[结论]遗传背景相同的虫株,其药物敏感性也相同。
[Objective] The study aimed to discuss the sensitivity of a precocious line of Eimeria acervulina and its parent strain to the conventional anticoccidial drugs.[Method] Eight kinds of anticoccidial drugs including diclazuril,robenidine,dinitolmide,decoquinate,nicarbazin,maduramicin,salinomycin and lasalocidt were selected to make to test in chicken and the comprehensive evaluation was conducted on base of the 4 indexes including the percent of optimum anticoccidial activity（POAA）,reduction of lesion scores（RLS）,relative oocyst production（ROP） and anticoc cidial index（ACI）.[Result] The precocious line of E.acervulina and its parent strain were completely sensitive to diclazuril,robenidine,decoquinate,nicarbazin,maduramicin and lasalocid,partly sensitive to salinomycin and not sensitive to dinitolmide.[Conclusion] The Eimeria strains with same genetic background had equal sensitivity to the drug..
