Abstract

Eimeria trachemydis n. sp. is described from the feces of 3/71 (4.2%) red-eared sliders, Trachemys scripta elegans, in Texas. Oocysts of the new species are ellipsoidal, 25.0 x 13.6 (20.8-30.4 x 12.0-16.0) µm, with a smooth, thin, apparently single-layered wall. A polar granule and oocyst residuum are present but a micropyle is absent. Sporocysts are elongate, 14.4 x 5.6 (12.8-16.0 x 5.0-6.4) µm, each with a Stieda body consisting of a slightly flattened region of the sporocyst wall bearing 2-5 stalked filaments; substieda body absent. Sporocyst residuum present, composed of a cluster of nonmembrane-bound granules. Sporozoites are elongate, 12.2 x 2.7 (11.2-14.4 x 2.4-3.2) µm in situ, each containing a spherical or ellipsoidal anterior refractile body and 1 (occasionally 2) midposterior spherical or ellipsoidal refractile bodies. A nucleus is located between the refractile bodies. In addition, prevalence data and specific identifications are presented on 10 other eimerians recovered from this host.
