|
|
|
what is the life cycle of malaria?
|
sporozoites-mosquito bite
travels to liver. THEN the sporozoites mature to form schizonts which rupture in the blood and release merozoites. merozoites infect RBC and asexually reproduce to form troposites troposites grow to form mature schizonts which rupture |
|

RBCs are hemolysed when the merozoites are released from the cell. it also causes the RBCs to stick together in small blood vessels
|
|
|
why would a patient with malaria have splenomegly
