艾美耳球虫发生季节变化的研究。在芬兰的田鼠种群中，三种宿主的感染率和感染密度均在初秋达到高峰。在冬末田鼠种群的主要崩溃之前和期间，艾美耳球虫感染的低患病率和密度表明，这些生物体虽然具有潜在的致病性，但并不显著导致周期性田鼠种群的急剧下降。
Study of seasonal changes in the occurrence of Eimeria spp. in Microtus agrestis, Clethrionomys glareolus and Microtus oeconomus populations in Finland showed distinct seasonal variation in all three host species: the peaks occurred in both prevalence and density of infection in early autumn. The low prevalence and density of eimerian infections before and during the main crash of vole populations in late winter indicate that these organisms, although potentially pathogenic, do not significantly contribute to the drastic decline in cyclic vole populations.
