Identification at species level is crucial for a better understanding of the epidemiology and ecology of these parasites, but an accurate diagnosis based only on morphology is difficult. In Brazil, genetic characterization of anisakids is still rare, with <jats:italic>Anisakis typica<\/jats:italic> and <jats:italic>A. physeteris<\/jats:italic> being the only two species identified by genetic markers until now. The definitive hosts of <jats:italic>A. nascettii<\/jats:italic> are <jats:italic>Mesoplodon grayi<\/jats:italic>, <jats:italic>M. bowdoini<\/jats:italic>, <jats:italic>M. layardii<\/jats:italic> and <jats:italic>M. mirus<\/jats:italic>. Geographical locations of <jats:italic>A. nascettii<\/jats:italic> include the coasts of New Zealand, South Africa and Europe. In this study, a nematode was collected from a Gervais' beaked whale, <jats:italic>Mesoplodon europaeus<\/jats:italic>, stranded in Cear\u00e1 State, north-east Brazil. Genetic analysis based on 18S rDNA, internal transcribed spacer (ITS) region and mtDNA <jats:italic>cox<\/jats:italic>2 gene revealed 100% identity with <jats:italic>Anisakis<\/jats:italic> sp. U94365, 99% with <jats:italic>Anisakis<\/jats:italic> sp. (MP-2005 EU718477 <jats:italic>A. nascettii<\/jats:italic>) and 99% with <jats:italic>A. nascettii<\/jats:italic> DQ116431, respectively. Phylogenetic analyses of ITS and <jats:italic>cox<\/jats:italic>2 sequences using both neighbour-joining and maximum-likelihood methods provided strong support for a clade with only <jats:italic>A. nascettii<\/jats:italic> specimens. This study demonstrated for the first time the identification of <jats:italic>A. nascettii<\/jats:italic> in the Brazilian Atlantic Coast, revealing a wider geographical distribution of this parasite worldwide and extending the range of its definitive hosts to a new <jats:italic>Mesoplodon<\/jats:italic> species, <jats:italic>M. europaeus<\/jats:italic>, the Gervais' beaked whale.<\/jats:p>","DOI":"10.1017\/s0022149x14000765","type":"journal-article","created":{"date-parts":[[2014,10,28]],"date-time":"2014-10-28T10:04:58Z","timestamp":1414490698000},"page":"48-53","source":"Crossref","is-referenced-by-count":11,"title":["First record of the anisakid nematode <i>Anisakis nascettii<\/i> in the Gervais' beaked whale <i>Mesoplodon europaeus<\/i> from Brazil"],"prefix":"10.1017","volume":"90","author":[{"given":"M.I.N.","family":"Di Azevedo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.L.","family":"Carvalho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.M.","family":"I\u00f1iguez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2014,10,28]]},"reference":[{"key":"S0022149X14000765_ref15","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-308X(08)00202-9"},{"key":"S0022149X14000765_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7519(99)00178-2"},{"key":"S0022149X14000765_ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2011.01.001"},{"key":"S0022149X14000765_ref20","doi-asserted-by":"publisher","DOI":"10.1645\/0022-3395(2000)086[0380:POTANA]2.0.CO;2"},{"key":"S0022149X14000765_ref13","doi-asserted-by":"publisher","DOI":"10.5597\/lajam00059"},{"key":"S0022149X14000765_ref26","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/22.22.4673"},{"key":"S0022149X14000765_ref28","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2010.06.023"},{"key":"S0022149X14000765_ref22","doi-asserted-by":"publisher","DOI":"10.1578\/01675420360736604"},{"key":"S0022149X14000765_ref2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0040447"},{"key":"S0022149X14000765_ref17","doi-asserted-by":"publisher","DOI":"10.1017\/S0022149X07754718"},{"key":"S0022149X14000765_ref18","doi-asserted-by":"publisher","DOI":"10.1007\/s11230-009-9212-8"},{"key":"S0022149X14000765_ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s00436-010-2226-y"},{"key":"S0022149X14000765_ref27","first-page":"95","article-title":"BioEdit: a user-friendly biological sequence alignment editor and analysis program for Windows 95\/98\/NT","volume":"41","author":"Hall","year":"1999","journal-title":"Nucleic Acids Symposium"},{"key":"S0022149X14000765_ref4","unstructured":"Culik B.M. 2010 Odontocetes \u2013 the toothed whales.
