Scanning electron micrograph showing schizogony of P. olseni. a. Immature trophozoite with a spherical or irregular shape on the fifth day after the release of zoospores to the medium; scale bar = 1 μm. b. Mature trophozoite with a smooth surface on the ninth day; scale bar = 5 μm. c. Early schizont showing an early cleavage furrow (arrowhead) on the twelfth day; scale bar = 5 μm. d. Morula stage, showing approximately 100 irregularly shaped merozoites on the thirteenth day. Scale bar = 5 μm. e-f. Rupture of the schizont cellular membrane and release of spherically shaped merozoites on the fifteenth day; E: scale bar = 5 μm; F: scale bar = 15 μm. Asterisk indicates merozoites
