Blood smears from 27 turtles (15 Emydura signata, nine Elseya latisternum, and three Chelodina longicollis) from southeastern Queensland (Australia) were examined for infections by hemoprotozoan parasites between January and June 1999. Infections were found in 26 (96%) of the turtles. Twenty five (93%) were infected with the adeleorin coccidian Haemogregarina clelandi, eight (30%) with the hemosporidian Haemoproteus chelodinae, 11 (41%) with the kinetoplastid flagellate Trypanosoma chelodinae, and eight (30%) with a novel Trypanosoma sp. Despite the high prevalence and intensity of infections, there was no evidence of clinical disease in any of the turtles.
