Oocysts of Eimeria maxima inoculated into guinea fowl do not develop. Infection occurs when intestinal mucosa or liver tissue from guinea fowl given E. maxima is transferred to susceptible chickens. By transferring material at different times after inoculation, it was shown that most of the stages are lost between 6 and 12 h and few, if any, survive to 48 h. Sporozoites of E. tenella had low infectivity after 48 h contact in vitro with peritoneal macrophages from guinea fowls and turkeys. Sporozoites of E. grenieri from the guinea fowl appeared to be destroyed within macrophages taken from chickens.
接种到珍珠鸡体内的巨型艾美耳球虫卵囊不会发育。当将感染巨型艾美耳球虫的珍珠鸡的肠黏膜或肝组织转移到易感鸡时，就会发生感染。通过在接种后不同时间转移材料，结果表明，大多数阶段在6至12小时之间消失，很少有（如果有的话）能存活到48小时。柔嫩艾美耳球虫的子孢子在体外与珍珠鸡和火鸡的腹腔巨噬细胞接触48小时后，感染力较低。来自珍珠鸡的格氏艾美耳球虫的子孢子似乎在取自鸡的巨噬细胞内被破坏。
