Photomicrograph depicting differences in Giemsa stained renal tissue from Plasmodium PCR positive sample for Pv and Pk positive renal core (a–c) vs. Plasmodium PCR negative sample (d–f). Giemsa stain highlights ring stage parasites (a, 10×, b, 40×, black arrows indicate parasites and c, inset: expanded image of parasites indicated by black arrows in b) within renal peritubular capillaries consistent with the presence of the malaria parasite. Plasmodium PCR negative renal biopsy did not demonstrate similar structures in the photomicrograph (d, 10×; e, 20× and f, 40×)
