Figure 1. Parasitemia percentage. Trend of patient’s percentage of parasitemia on peripheral blood smear over the follow-up period. Inset top: Giemsa-stained thick blood film demonstrating numerous Babesia species parasites. Each parasite has a round purple chromatin dot with an associated blue-gray cytoplasm (arrows). The percentage of parasitemia calculated from the corresponding thin film was 6.13%. Inset bottom: Giemsa-stained thin blood film showing 2 erythrocytes with intraerythrocytic parasites (arrows). The parasite forms are atypical, likely reflecting their exposure to antiparasitic agents. The overall percentage of parasitemia was 1.02%.
