title: Taxonomy and review of the coccidian genus Cryptosporidium (protozoa, apicomplexa).
abstract: Reports of Cryptosporidium in various hosts and cross-transmission experiments are reviewed. Cryptosporidium has been found in mammals (Primates, Artiodactyla, Perissodactyla , Carnivora, Lagomorpha, and Rodentia), birds, reptiles, and fish. The only cross-transmission attempts that have been made have been from mammals to other mammals and to a few birds. Names have been given to 19 "species," but it is concluded that only four of these should be considered valid at present. These are: C. muris Tyzzer, 1907 in mammals, C. meleagridis Slavin , 1955 in birds, C. crotali Triffit , 1925 in reptiles, and C. nasorum Hoover , Hoerr , Carlton , Hinsman & Ferguson, 1981 in fish.
