Summary

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.
