Early development of Eimeria papillata (Apicomplexa) in the mouse was evaluated using Nomarski interference‐contrast and brightfield microscopy. Sporozoite‐shaped meronts, which were motile and contained a large posterior refractile body and a smaller anterior refractile body, were observed entering and leaving host cells in the jejunum of an experimentally infected mouse at 26 h post inoculation (HPI). However, early developmental stages were not observed in tissue of the duodenum, ileum, cecum and colon. the mean length and width of these meronts (n = 20) were 12.0 μm and 3.7 μm, respectively. Spherical or subspherical meronts containing crescent‐shaped merozoites were observed at 36 HPI.
