Comparison of Giemsa and IHC under two different magnifications. A low parasitaemic placental sample was stained by Giemsa (a, b) and by IHC (c, d) and photographed under two magnifications (erythrocytes are 6 μ in diameter). Under higher magnifications of Giemsa-stained samples, the intra-erythrocytic malaria pigment (filled arrowheads) can be distinguished from formalin pigment (empty arrowheads) while by IHC the parasites are visible under low magnification. Images were made from placental biopsies used as positive control for this IHC obtained in a previously published study in Uganda [16]
