Immunoelectron micrography on streptolysin-O permeablised mature trophozoite (36 h after invasion of the merozoites) infected cells. FEST is associated with Golgi-like structures in the red cell cytoplasm (a and b); vesicles in the red cell cytoplasm (c); the parasite plasma membrane (d) and membranous structures in the red cell cytoplasm (e); knobs in the parasitised red cell plasma membrane (f–h). A cross-section through a parasitised red cell is shown in (i). FEST is associated with membranous structures in the red cell and with the red cell membrane, particularly at parasite-induced knobs.
