- An oocyst with one sporoblast is released in stool of infected person
- After the oocyst has been released, the sporoblast matures further and divides into two
- After the sporoblasts divide they create a cyst wall and become sporocysts
- The sporocysts each divide twice, resulting in four You do not have permission to view the full content of this post. Log in or register now.
- Transmission occurs when these mature oocysts are ingested
- The sporocysts excyst in the small intestine where sporozoites are released
- The sporozoites then invade epithelial cells and You do not have permission to view the full content of this post. Log in or register now.is initiated
- When the schizonts rupture, mereozoites are released and continue to invade more epithelial cells
- Trophozoites develop into schizonts, containing many mereozoites
- After about one week, development of male and female gametocytes begin in the mereozoites
- Fertilization results in the development of oocysts, which are released in the stool You do not have permission to view the full content of this post. Log in or register now.You do not have permission to view the full content of this post. Log in or register now.
