*Direct life cycle

*1 week prepatent period

*After oocysts are ingested, sporozoites are released which penetrate the intestinal epithelium

*2 asexual phases of multiplication called schizogony occur followed by a phase of sexual multiplication called gametogony

*Zygote develops into an oocyst which is then shed in the faeces
**Oocyst measures 20-30μm

*For each oocyst ingested, thousands are shed

*Life cycle is '''self-limiting'''
**Organisms from a single infection go through the sequence of developmental stages synchronously
**Organisms leave the body simultaneously as oocysts

*Oocysts are only infective once they have sporulated
**Sporulation requires warmth, moisture and oxygen
**Takes 2-3 days in broiler houses

*Oocysts contain 4 sporocysts each with 2 sporozoites
