Figure 2

Ultrastructure of T. gondii tachyzoites cultured in human foreskin fibroblasts (HFF). Parasites proliferated intracellularly within a parasitophorous vacuole (A,C), and corresponding higher magnification views are depicted in (B) and (D–E). A tachyzoite undergoing endodyogeny forming a daughter zoite (dz) is shown in (F), and structural details of the mitochondrion are shown at higher magnification in (G). Notice distinct apicomplexan organelles at the anterior end of tachyzoites such as the conoid (con), rhoptries (rop) and micronemes (mic). Dense granules (dg) and parts of the mitochondrion (mt) are dispersed within the cytoplasm; nuc = nucleus. Bars in (A) = 1 µm; (B) = 0.35 µm; (C) = 1 µm; (D) = 0.55 µm; (E) = 0.42 µm; (F) = 0.55 µm; (G) = 0.18 µm.
