Helminths of the common opossum Didelphis marsupialis (Didelphimorphia: Didelphidae), with a checklist of helminths parasitizing marsupials from Peru

Between May and November 2015, 8 specimens of Didelphis marsupialis Linnaeus, 1758 (Didelphimorphia: Didelphidae) collected in San Martín, Peru were examined for the presence of helminths. A total of 582 helminths representing 11 taxa were identified (2 digeneans and 9 nematodes). Five new host reco...

Zusammenfassung:Between May and November 2015, 8 specimens of Didelphis marsupialis Linnaeus, 1758 (Didelphimorphia: Didelphidae) collected in San Martín, Peru were examined for the presence of helminths. A total of 582 helminths representing 11 taxa were identified (2 digeneans and 9 nematodes). Five new host records and 4 species of nematodes [Gongylonemoides marsupialis (Vaz & Pereira, 1934) Freitas & Lent, 1937, Trichuris didelphis Babero, 1960, Viannaia hamata Travassos, 1914 and Viannaia viannaia Travassos, 1914] are added to the composition of the helminth fauna of the marsupials in this country. Further, a checklist of all available published accounts of helminth parasites reported from Peru is provided. To date, a total of 38 helminth parasites have been recorded. Digeneans have the highest species richness in number and percentage (n=19, 50%), followed by nematodes (n=17, 45%) and acanthocephalans (n=2, 5%). The parasites with the highest number of records were the digeneans Plagiorchis didelphidis (Parona, 1896) Stossich, 1904 (n=4) and Rhopalias coronatus Kifune & Uyema, 1982 (n=4) and the nematode Aspidodera sp. (n=4). Additional sampling in this country will probably increase the richness of the helminthological inventory of this group of mammals. Entre mayo y noviembre del 2015, 8 ejemplares de Didelphis marsupialis Linnaeus, 1758 (Didelphimorphia: Didelphidae) recolectados en San Martín, Perú, fueron examinados en busca de helmintos. Un total de 582 helmintos representando 11 taxones fueron identificados (2 digéneos y 9 nemátodos). Cinco registros nuevos y 4 especies de nemátodos [Gongylonemoides marsupialis (Vaz y Pereira, 1934) Freitas y Lent, 1937, Trichuris didelphis Babero, 1960, Viannaia hamata Travassos, 1914 y Viannaia viannaia Travassos, 1914] se agregan a la composición de la fauna de helmintos de marsupiales de Perú. Además, se proporciona una lista de todos los registros publicados de este grupo de parásitos para marsupiales en dicho país. Hasta la fecha, se ha registrado un total de 38 helmintos; los digéneos tienen la mayor riqueza de especies en número y porcentaje (n=19, 50%), seguido por los nemátodos (n=17, 45%) y acantocéfalos (n=2, 5%). Los parásitos con mayor número de registros fueron los digéneos Plagiorchis didelphidis (Parona, 1896) Stossich, 1904 (n=4) y Rhopalias coronatus Kifune y Uyema, 1982 (n=4) y el nemátodo Aspidodera sp. (n=4). Nuevos muestreos en este país probablemente aumentarán la riqueza del inventario helmintológico
