Figure. Thin blood film photographs showing Babesia-like early tetrads (panels A, B) and pleiomorphic later-stage parasites (panels C, D) in an HIV-positive patient from Zimbabwe living in South Africa. The multiply infected erythrocytes and unusual morphology suggested nonmalaria parasites and were later determined to be the rodent piroplasm Anthemosoma garnhami, related to Babesia spp. Slides stained with 10% Giemsa, pH 7.2, for 20 min; original magnification ×1,000.
