Oocysts are shed into the environment
- Each contains one sporoblast
- Remain viable for months
Oocysts sporulate in the environment before becoming infectious
- Sporoblasts dividing and maturing into two sporocysts, which in turn divide and mature into two sporozoites each
The sporulated oocyst (containing four sporozoites) is ingested
In the proximal small bowel, the sporozoites are released and develop into merozoites
The merozoites go through asexual reproduction, eventually followed by sexual reproduction that results in development of an immature oocyst, which is shed
