The white-eared opossum, <jats:italic>Didelphis albiventris<\/jats:italic>, and the southern black-eared opossum, <jats:italic>D. aurita<\/jats:italic> are sympatric marsupials, and the most frequent mammals in the northern Misiones. In this study, we describe the helminth assemblages from both <jats:italic>D. albiventris<\/jats:italic> and <jats:italic>D. aurita<\/jats:italic> in the northern AAF. We found a total of 15 species of helminths: 2 trematodes, 1 cestode, 11 nematodes and 1 acanthocephalan. The specific richness in <jats:italic>D. albiventris<\/jats:italic> was 12, while in <jats:italic>D. aurita<\/jats:italic> was it 13. Both opossum\u2019s species share 10 helminth species; <jats:italic>D. albiventris<\/jats:italic> presented <jats:italic>Capillaria<\/jats:italic> sp. 2 and <jats:italic>Globocephalus marsupials<\/jats:italic>, absent in <jats:italic>D. aurita<\/jats:italic>; while <jats:italic>D. aurita<\/jats:italic> presented <jats:italic>Trichuris didelphis, Capillaria<\/jats:italic> sp. 1, and <jats:italic>Travassostrongylus orloffi<\/jats:italic>, absent in <jats:italic>D. albiventris. Cruzia tentaculata<\/jats:italic> registered the highest prevalence in both opossum species. Seven out of the 12 helminth species identified in <jats:italic>D. albiventri<\/jats:italic>s have an indirect life cycle. Similarly, in <jats:italic>D. aurita<\/jats:italic>, 5 out of 13 helminth species exhibit an indirect life cycle. This suggests that nearly half of the assemblage of helminth in both opossum species need an intermediate host acquired through the diet. We also present new records for Argentina including <jats:italic>Trichuris minuta, G. marsupialis, Viannaia viannai, T. orloffi<\/jats:italic> and <jats:italic>T. callis<\/jats:italic>. This is the first time the helminth assemblage has been described for <jats:italic>D. aurita<\/jats:italic> in Argentina.<\/jats:p>","DOI":"10.1017\/s0031182025000563","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T07:11:37Z","timestamp":1745478697000},"page":"551-562","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":1,"title":["Helminths assemblage in two opossum\u2019s species, <i>Didelphis albiventris<\/i> and <i>Didelphis aurita<\/i> (Mammalia: Didelphimorphia), from the Atlantic Forest of Argentina"],"prefix":"10.1017","volume":"152","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-3980-7807","authenticated-orcid":false,"given":"B\u00e1rbara Betina","family":"Hartmann","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ezequiel Andres","family":"Vanderhoeven","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dante Luis","family":"Di Nucci","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agust\u00edn","family":"Solari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana","family":"Notarnicola","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,4,24]]},"container-title":["Parasitology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0031182025000563","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,2]],"date-time":"2025-07-02T08:43:39Z","timestamp":1751445819000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0031182025000563\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2025,4]]}},"alternative-id":["S0031182025000563"],"URL":"https:\/\/doi.org\/10.1017\/s0031182025000563","relation":{},"ISSN":["0031-1820","1469-8161"],"issn-type":[{"value":"0031-1820","type":"print"},{"value":"1469-8161","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4]]},"assertion":[{"value":"\u00a9 The Author(s), 2025.
