*The '''oocyst''' is the resistant stage in the environment
 
 
 
*The infective '''sporozoite''' is released from the oocyst
 
 
 
*Inside the host, the sporozoites invade the intestinal epithelial tissue
 
**Sporozoites feed and grow
 
 
 
*As the sporozoite grows the nucleus divides forming a '''schizont'''
 
 
 
*The schizont contains numerous elongated '''merozoites'''
 
 
 
*The formation of merozoites is the first asexual reproductive stage called '''schizogony'''
 
 
 
*The schizont ruptures releasing the merozoites which also invade the epithelial cells
 
 
 
*Another generation of schizonts form which is the beginning of the sexual phase of reproduction called '''gametogony'''
 
 
 
*The merozoites form male '''microgamonts''' or female '''macrogamonts'''
 
**Collectively known as gamonts or gametocytes
 
 
 
*The microgamonts released from the microgametocyte penetrate and fertilise the macrogamont (which is contained within the macrogametocyte)
 
 
 
*Gametogony forms the '''zygote'''
 
**Surrounded by a cyst wall
 
**Forms the '''oocyst'''
 
 
 
*The oocyst is passed in the faeces and is unsporulated
 
 
 
*The oocyst becomes sporulated in the second asexual reproductive phase called '''sporogony'''
 
 
 
*Once the oocyst is sporulated it is infective
