Host Range Characteristics of the Primate Coccidian, 'Isospora arctopitheci' Rodhain 1933 (Protozoa: Eimeriidae).

摘要

Studies were conducted on 35 primates, 12 carnivores, and 2 marsupials to determine their susceptibility to the primate coccidian, Isospora arctopitheci. Patent oocyst infections resulted in 12 of the 14 species of animals investigated. These included 6 genera of New World primates native to Panama: Saguinus geoffroyi, Aotus trivirgatus, Ateles fusciceps, Cebus capucinus, Alouatta villosa, and Saimiri sciureus. In addition 4 families of carnivores (2 domestic and 2 sylvatic) and 1 species of marsupial became infected following experimental exposure. These animals are represented respectively by the following 6 genera and species: Canis familiaris; Felis catus; Nasua nasua, and Potos flavus; Eiria barbara; and Didephis marsupialis. Four Old World rhesus monkeys, Macaca mulatta, and 1 carnivore, Bassaricyon gabbii, did not become oocyst positive. This unusually large host range makes this isosporan unique among the coccidia that have been investigated to date. (Author)
