摘要

We document morphological descriptions for 3 newly described Eimeria spp. that infect springbok (Antidorcas marsupialis). Eimeria antidorcasi n. sp. oocysts are ovoid, with average size (n = 346) 26.2 x 18.8 (19.2-33.5 x 13.1-26.5) mu m, a length/width ratio of 1.4 (1.2-2.0), a micropyle, and a polar granule sometimes present. Sporocysts are ovoid (n = 336), 11.3 x 7.3 (6.0-14.6 x 5.2-9.8) mu m, with a length/width ratio of 1.5 (1.1-2.0), a Stieda body, a prominent, ovoid sporocyst residuum, and one refractile body per sporozoite. Eimeria versfeldi n. sp. oocysts are ellipsoid (n = 136), 38.9 x 26.6 (27.8-48.2 x 21.2-31.0) mu m, with a length/width ratio of 1.5 (1.2-2.0), a micropyle cap with submicropylar material, and 2-4 polar granules. Sporocysts are elongate-ovoid (n = 132), 18.3 x 9.2 (13.2-22.8 x 6.8-11.2) mu m, with a length/width ratio of 2.0 (1.3-2.5), a Stieda body, a small sporocyst residuum present, and an evident nucleus and two refractile bodies per sporozoite. Eimeria gasawayi n. sp. oocysts are subspheroid (n = 87), 14.8 x 13.6 (11.5-20.0 x 11.1-18.2) mu m, with a length/width ratio of 1.1 (1.0-1.2), and no micropyle. Sporocysts are elongate-ovoid (n = 82), 9.0 x 4.6 (5.5-12.5 x 3.6-6.4) mu m, with a length/width ratio of 2.0 (1.3-2.4), a small Stieda body, and an irregularly shaped sporocyst residuum present. These are the first Eimeria spp. described from springbok.
