Parasitological diagnosis of Didelphis albiventris Lund, 1841 and Lutreolina crassicaudata Desmarest, 1804 (Marsupialia: Didelphidae) of free life in Rio Grande do Sul, Brazil
The objective of this study is to evaluate the frequency of gastrointestinal parasites in free-living marsupials received at the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul, southern Brazil. Fecal samples from nine white-eared opossums (Didelphis albiventris Lund, 1841...

| Resumo: | The objective of this study is to evaluate the frequency of gastrointestinal parasites in free-living marsupials received at the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul, southern Brazil. Fecal samples from nine white-eared opossums (Didelphis albiventris Lund, 1841) and three thick-tailed opossums (Lutreolina crassicaudataDesmarest, 1804) were processed by the Willis and Lutz methods. Both species of marsupials presented nematode eggs and/or protozoan oocysts in their feces. In white-eared opossums, eggs of Ancylostoma spp. Ercolani, 1859 and Capillaria spp. Zeder, 1800 (4/8 - 50%), Ancylostoma spp. and Cruzia tentaculata (Rudolphi, 1819) Travassos, 1917 (2/8 - 25%), C. tentaculata (2/8 - 25%) and oocysts of Eimeria spp. Schneider, 1875 (1/8 - 12.5%) were identified. The only hatchling presented eggs of Ancylostoma spp., Trichuris spp. Roederer, 1761 and Rhopalia coronatus Stiles and Hassall, 1898. The three opossums presented eggs of Ancylostoma spp. (3/3 - 100%) and two also presented oocysts of Eimeria spp. (2/3 - 66.7%). All animals were dewormed and parasitological tests were repeated until negative results. Parasitological diagnosis is a protocol upon admission so that the response to treatment of the underlying pathology occurs without interference from parasitic diseases. |
