Q

cryptosporidium parvum lifecycle

A

Thin wall oocyst stays in host causing auto-infection & thick wall oocyst exits (pop out of cyst & penetrate intestinal mucosa)
- Oocyst -> Sporocyst -> Sporozoite ->Merozoite (trophozoite) -> Schizont (meront) -> Schizozoite (go b/w last 2, 3 times over and over) ->Gamonts (macro & micro) -> Fert of macro by micro -> Zygote
