Contracaecum jorgei in common snooks in Brazil: new host, locality record and remarks on misidentifications of Contracaecum spp. in GenBank
Contracaecum jorgei was recently described as a new anisakid species from the Argentine wolffish Hoplias argentinensis. This study aimed to report a new host and locality for C. jorgei and highlight inconsistencies in some Contracaecum spp. deposits based on sequence comparisons. Through morphometric analyses and comparative analyses of genetic sequences in GenBank, using a locus from the cytochrome oxidase subunit 2 gene, present specimens were identified as C. jorgei. Misidentified sequences of Contracaecum spp. were also observed and discussed. Thus, C. jorgei is reported for the first time in the Brazilian common snook Centropomus undecimalis, expanding the reports and, consequently, its geographic distribution in the Neotropical region.
