Tachyzoite - multiply and migrates to organs, then it goes bradyzoites, then this bradyzoites will be a part of gamogony and also will forms another tachyzoite. double check on it!!

I know!! I was having trouble too. But remember it is a CYCLE, so it depends of the life stage that you start with. In this case, it started AND ended with bradyzoites. The cat eats the mouse with a TISSUE CYST that liberates BRADYZOITES into its intestine and they transform into MEROZOITES (the sexual cells), these merozoites form an IMMATURE OOCYST that are then eliminated with feces. Now the OOCYST has to MATURE through sporulation, forming SPOROZOITES. these mature cysts can be ingested with water or vegetables by the intermediate hosts and follow the next path: The SPOROZOITES become TACHYZOITES that invade tissues (neurons, muscle, etc.) and end up forming bradyzoites, AGAIN, inside a TISSUE CYST (like the one that was inside the mouse that the cat ate at the beginning, which is also the way humans get infected, only instead of a mouse it is a pig, AND it would be brazyzoites, not sporozoites, that transform into tachyzoites) and thus, the cycle starts again.
