Babesia venatorum parasites in blood of patient with autochthonous human babesiosis, the Netherlands. Giemsa-stained thin smear from blood of patient before start of treatment and visualized with light microscopy (original magnification ×1,250) shows small and pleomorphic amoeboid and vacuolar asexual stages of Babesia spp., positioned within and outside red blood cells, which is typically observed in human babesiosis. Of note, 1 dark blue–stained Howell-Jolly body is observed.
