Sporulated oocysts of Isospora bertoi n. sp. are spherical to subspherical; 23.6 (21.1-26.5) x 22.0 (19.4-24.6) µm; shape Index (L/W ratio) 1.1 (1.0-1.2) µm; with bilayer smooth walls, ~1.1 μm. Micropyle and oocyst residuum are absent, but polar granules are present. Sporocysts are elongated ellipsoidal, 16.2 (13.6-17.9) x 10.1 (8.9-12.4) µm. Stieda body is button-shaped and Sub-Stieda and Para-Stieda body are absent. Sporocyst residuum is compact and composed of hundreds of granules scattered among the sporozoites.
