*The '''oocyst''' is the resistant stage in the environment
+
Coccidia have three major stages to their life cycle: Sporogony, Schizogony, Gametogony. The first two stages are asexual, with sexual reproduction occurring in the third stage.
   −
*The infective '''sporozoite''' is released from the oocyst
+
===Sporogony===
 +
This is the fist stage of the coccidia life cycle and occurs exogenously in the environment. Sporozoites develop within the oocyst before it becomes infective. Once the sporozoites have been formed the oocyst is infective and on ingestion by the host will release sporozoites to invade intestinal epithelium.
   −
*Inside the host, the sporozoites invade the intestinal epithelial tissue

===Schizogony===
 +
Sporozoites grow within intestinal epithelial cells
