Coccidia
Coccidium (Eimeria schubergi) 
Endocellular parasite of epithelial cells of the divestive tract of Lithobius (Chilopoda); life cycle with different stages: infection starts with the ingestion of an oocyst(20). The sporozoites emerging from a sporocyst (1,2) penetrate into host cells, and swelling up become trophozoites (3-6), which undergo to 2 or 3 schyzogonies. The resulting merozoites (7,8) leave the cells to infect other cells. When a certain degree of infection is reached merozoites become gamonts, macro- and microgamonts (9, 10), which develop in macro- and microgametocytes (11,12): after the fertilization of gametes (13), the zygote becomes oocyst and undergoes to a meiosis and a subsequent mitosis (14-17). Eventually an oocyst (18-20) has 4 sporocysts with 2 sporozoites each one.

Phylum Apicomplexa
Coccidia, Eimeriorina
Coccidium (Eimeria schubergi)
Parassita endocellulare dell’epitelio intestinale di Lithobius (Chilopoda, centopiedi); è rappresentato il ciclo vitale con i differenti stadi: l’infezione inizia con l’ingestione delle oocisti (20). Nell’intestino gli sporozoiti (1,2) dapprima escono dalle sporocisti e poi penetrano nelle cellule dell’ospite,  diventano accrescendosi trofozoiti (3-6), che vanno incontro a due o tre fasi schizogoniche. I merozoiti (7,8) formatisi escono dalla cellula per infettarne di nuove. Quando viene raggiunto un certo  grado d’infezione i merozoiti si trasformano in gamonti, macro- e microgamonti (9, 10), che danno origine a macro- e microgameti (11,12). Dopo la fecondazione (13), lo zigote diventa oocisti e va incontro a meiosi e ad una successiva mitosi (14-17). Le oocisti (18-20), infine, contengono 4 sporocisti con 2 sporozoiti ciascuna.
