Monkey Malaria in a European Traveler Returning from Malaysia
Figure

Figure. Microscopic findings in the thin blood smears of a patient with Plasmodium knowlesi malaria. Early ring forms are shown in the first row, later trophozoites in the second and third rows, trophozoites resembling band forms in the fourth row, and putative early gametocytes or schizonts in the fifth row. Size of the infected erythrocytes is normal. Antimalarial medications, given 8 hours before the blood shown in the smear was drawn, could have affected morphology. (Original magnification ×1,000.)
