They stated that this is the first record of <jats:italic>Opisthorchis<\/jats:italic> sp. in birds in Vietnam. However, three <jats:italic>Opisthorchis<\/jats:italic> species \u2013 <jats:italic>O. cheelis<\/jats:italic>, <jats:italic>O. longissimus<\/jats:italic> and <jats:italic>O. parageminus<\/jats:italic> \u2013 in birds in Vietnam were described by Le in 2000. Amongst these, <jats:italic>O. parageminus<\/jats:italic> was first reported, by Oshmarin in 1970, as a new <jats:italic>Opisthorchis<\/jats:italic> species found in domestic ducks (<jats:italic>Anas platyrhynchos<\/jats:italic>) in Vietnam. Morphologially <jats:italic>O. viverrini<\/jats:italic>-like flukes described by Dao <jats:italic>et al.<\/jats:italic> are much more similar to <jats:italic>O. parageminus<\/jats:italic> than to <jats:italic>O. viverrini<\/jats:italic>. The phylogenetic trees of internal transcribed spacer 2 (ITS2) and cytochrome oxidase 1 (CO1) gene sequences also showed that the <jats:italic>O. viverrini<\/jats:italic>-like liver flukes from domestic ducks were closer to <jats:italic>O. lobatus<\/jats:italic> than to <jats:italic>O. viverrini<\/jats:italic>. Therefore, <jats:italic>O. viverrini<\/jats:italic>-like liver flukes reported by Dao <jats:italic>et al.<\/jats:italic> (2013) are most likely to be <jats:italic>O. parageminus<\/jats:italic>.<\/jats:p>","DOI":"10.1017\/s0022149x13000709","type":"journal-article","created":{"date-parts":[[2013,10,25]],"date-time":"2013-10-25T13:26:37Z","timestamp":1382707597000},"page":"255-256","source":"Crossref","is-referenced-by-count":17,"title":["Is <i>Opisthorchis viverrini<\/i> an avian liver fluke?"],"prefix":"10.1017","volume":"89","author":[{"given":"Y.","family":"Nawa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.N.","family":"Doanh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U.","family":"Thaenkham","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2013,10,25]]},"reference":[{"key":"S0022149X13000709_ref7","doi-asserted-by":"publisher","DOI":"10.1645\/GE-2764.1"},{"key":"S0022149X13000709_ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-308X(07)65004-0"},{"key":"S0022149X13000709_ref5","first-page":"5","volume-title":"Helminths of animals of Southeast Asia","author":"Oshmarin","year":"1970"},{"key":"S0022149X13000709_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.actatropica.2003.05.001"},{"key":"S0022149X13000709_ref3","first-page":"236","volume-title":"Fauna of Vietnam","author":"Le","year":"2000"},{"key":"S0022149X13000709_ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.pt.2012.07.006"},{"key":"S0022149X13000709_ref1","article-title":"Opisthorchis viverrini-like fluke in birds from Vietnam: morphological variability and rDNA\/mtDNA sequence confirmation","author":"Dao","year":"2013","journal-title":"Journal of Helminthology"}],"container-title":["Journal of Helminthology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022149X13000709","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,21]],"date-time":"2019-04-21T03:38:20Z","timestamp":1555817900000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022149X13000709\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,10,25]]},"references-count":7,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2015,3]]}},"alternative-id":["S0022149X13000709"],"URL":"https:\/\/doi.org\/10.1017\/s0022149x13000709","relation":{},"ISSN":["0022-149X","1475-2697"],"issn-type":[{"value":"0022-149X","type":"print"},{"value":"1475-2697","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,10,25]]}}}
