Malarial pigment is formed by:

Ans. is 'c' i.e., Hemoglobin(Ref: Parasitology, Panicker, 6th/e, p. 71)* The malarial parasite (plasmodium) feeds on the haemoglobin of the erythrocyte. Haematin globin pigment - Haemoglobin left behind as a residue after metabolism of parasite.* These iron containing pigments formed from haemoglobin accumulate in the body of the parasite as dark granules, which becomes more prominent, as the parasite grows.* The appearance of malaria pigments varies in the different species.# P. vivax - Yellowish brown# P. falciparum - Dark brown# P. malariae - Dark brown# P. ovale - Yellowish brownNote: The malaria pigment released when the parasitized cells rupture is taken up by reticuloendothelial cells. Such pigment laden cells in the internal organs provide histological evidence of previous malarial infection.
