Life cycle of Plasmodium (malarial parasite) (i) The infected female Anopheles mosquito transfers the infectious form of Plasmodium, i.e. sporozoites to the human body by biting. (ii) Sporozoites reach the liver cells, where they multiply. (iii) This is followed by their attack on red blood cells resulting in the rupture of RBCs. (iv) Ruptured RBCs release a toxin called haemozoin, responsible for recurring fever, chills and shivering. (v) The parasite enter female Anopheleswhen they bite an infected person. (vi) In the body of mosquito, they fertilise and multiply in stomach wall. (vii) Sporozoites are then again transferred to the human body by mosquito bite.
Trace the life cycle of Plasmodium in humans from the stage of entry until it is picked up by the female Anopheles.
