Conversely, all metacestodes found in guanacos collected from Tierra del Fuego Island, where no pumas exist, were identified solely as <jats:italic>Echinococcus granulosus sensu stricto<\/jats:italic>. Additionally, this research highlights a tissue preference of <jats:italic>T. omissa<\/jats:italic> for liver, contrasting with <jats:italic>E. granulosus<\/jats:italic>, which predominantly affects the lungs in guanacos. We also report the infection of <jats:italic>T<\/jats:italic>. <jats:italic>pisiformis<\/jats:italic> in 1 guanaco. Our findings emphasize the need for accurate identification of metacestodes during meat inspection in an area where <jats:italic>T. omissa<\/jats:italic> and <jats:italic>E. granulosus<\/jats:italic> overlap. This research also contributes to increase the knowledge of parasite\u2013host dynamics in wildlife and underscores the importance of considering broader spectrum intermediate hosts in the epidemiology of parasitic infections.<\/jats:p>","DOI":"10.1017\/s0031182024001501","type":"journal-article","created":{"date-parts":[[2024,11,18]],"date-time":"2024-11-18T09:21:04Z","timestamp":1731921664000},"page":"1580-1586","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":3,"title":["Prevalence study of <i>Echinococcus granulosus<\/i> in guanaco (<i>Lama guanicoe<\/i>) from the Chilean Patagonia unexpectedly reveals the southernmost limit of <i>Taenia omissa<\/i>"],"prefix":"10.1017","volume":"151","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8069-7607","authenticated-orcid":false,"given":"Cristian A.","family":"Alvarez Rojas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Francisco","family":"Alvarez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juliana","family":"Iglesias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8330-6416","authenticated-orcid":false,"given":"Anson V.","family":"Koehler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristian","family":"Bonacic","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2024,11,18]]},"reference":[{"key":"S0031182024001501_ref28","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182007002235"},{"key":"S0031182024001501_ref16","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth.4285"},{"key":"S0031182024001501_ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2017.09.007"},{"key":"S0031182024001501_ref18","doi-asserted-by":"publisher","DOI":"10.1111\/2041-210X.12410"},{"key":"S0031182024001501_ref21","doi-asserted-by":"publisher","DOI":"10.7589\/0090-3558-28.1.130"},{"key":"S0031182024001501_ref25","doi-asserted-by":"publisher","DOI":"10.7717\/peerj.4124"},{"key":"S0031182024001501_ref10","first-page":"331","article-title":"H\u00e1bitos alimentarios del puma (Puma concolor) e incidencia de la depredaci\u00f3n en la mortandad de guanacos (Lama guanicoe) en el noreste de la Patagonia","volume":"21","author":"Fern\u00e1ndez","year":"2014","journal-title":"Mastozoologia Neotropical"},{"key":"S0031182024001501_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.actatropica.2021.106178"},{"key":"S0031182024001501_ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s00436-023-07989-y"},{"key":"S0031182024001501_ref27","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msab120"},{"key":"S0031182024001501_ref29","volume-title":"Estudio de prevalencia de hidatidosis en guanacos (Lama guanicoe) Tierra del Fuego, Chile","author":"Valdebenito D\u00edaz","year":"2008"},{"key":"S0031182024001501_ref2","doi-asserted-by":"publisher","DOI":"10.1007\/s11252-022-01320-w"},{"key":"S0031182024001501_ref26","doi-asserted-by":"publisher","DOI":"10.7589\/0090-3558-23.1.113"},{"key":"S0031182024001501_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/0166-6851(92)90109-W"},{"key":"S0031182024001501_ref22","volume-title":"Subdepartamento de Epidemiolog\u00eda y Control de Enfermedades.
