<prompt> In a case of Plasmodium falciparum malaria, the peripheral blood smear does not demonstrate trophozoites and schizonts. The reason for this is:Apoptosis of red cells because of hemozoin pigmentsLysis of red cells with malarial parasiteInfested cells are trapped in the spleenInfested red blood cells stick to the capillaries  <response>: -Plasmodium falciparum is associated with infected red cells expressing PfEMP Plasmodium falciparum erythrocyte membrane protein leading to their attachment to the endothelial cells. -This leads to sequestration of infected red cells in the capillaries. -Thats the reason for the non-appearance of trophozoites and schizonts in the peripheral blood smear.
