Eimeria cotti, a gut dwelling coccidian parasite from bullhead (Cottus gobio) is described from fish collected from waters of a natural resort area in North-West Germany. All age groups of bullhead were found to be infected throughout the year at a prevalence of 43 out of 92 fish examined. Infected tissue contained merogonic, gamogonic and sporogonic developmental stages. Ultrastructural features of these stages conformed with those of other eimerian coccidia. Merozoites were formed by ectomerogony, macrogamonts exhibited a prominent electron dense inclusion, and mature oocysts had a stieda body.
科氏艾美球虫是一种寄生于杜父鱼肠道的球虫寄生虫，从德国西北部一个自然度假区水域采集的鱼类中被发现。所有年龄段的杜父鱼全年均有感染，在所检查的92条鱼中，感染率为43%。感染组织中含有裂殖生殖、配子生殖和孢子生殖发育阶段。这些阶段的超微结构特征与其他艾美球虫相符。裂殖子通过外质裂殖生殖形成，大配子体有一个明显的电子致密包涵体，成熟卵囊有一个斯氏体。
