Cryptosporidium parvum and Isospora belli are relatively easily identified with simple stains (Figs 1 and 2), but excretion in the stools is often intermittent.
Según la taxonomía actual, el género Eimeria forma parte de la siguiente clasificación: clase Sporozoasida, subclase Coccidiosina, orden Eucoccidiorida, suborden Eimeriodina, familia Eimeriidae, géneros Eimeria e Isospora (14).
Treatment of coccidia The life cycles of Eimeria and Isospora (the germs that cause coccidian) are considered self-limiting and end spontaneously within a few weeks unless a re-infection occurs.
