To analyze effect of diclazuril and maduramycin on 18S rDNA of Eimeria tenella, the 18S rDNA of sporulated oocyst of the E. tenella anti-diclazuril strain, the E. tenellaanti-maduramycin strain and the E. tenella drug-sensitive strain were cloned and sequenced, and were compared by using DNAStar 5.0 and RNADraw 1.1, respectively.

为探讨抗球虫药物地克珠利和马杜拉霉素对柔嫩艾美球虫18S rDNA的影响，分别对人工诱导的柔嫩艾美球虫地克珠利抗药株、马杜拉霉素抗药株和药物敏感株孢子化卵囊的18S rDNA基因进行了克隆测序，并通过生物信息软件进行对比差异分析。

It"s vegetal mycelia were colorless, smooth, 1.2μm～3.0μm crude, manyconidiogenous cells born on vegetal mycelia, sometimes as many as a dozen,a very small number were single. The base of conidiogenous cell wasenlarged and many of them were bottle-shaped or spherical. The upper ofconidiogenous cell extended into a conidiogenous axis of 1μm wide and 14μm length which was the knee-bending ("Z like bending), there were small pectinae on the axis, conidium located on the small pectina.
