Clinostomidae are digeneans characterized by a complex taxonomic history, continuously under revision based on both morphological and molecular analysis. Among the 14 species considered valid so far Clinostomum phalacrocoracis has been well described only at the adult stage, whereas the morphology of the metacercarial stage has been reported only once. During a parasitological survey carried out on 262 wild cichlids sampled from Lake Kinneret (Israel) metacercariae referable to C. phalacrocoracis were found in 18 fingerlings. In this study, we report this clinostomid species for the first time in wild fish from Israel describing the metacercarial stage of Clinostomum phalacrocoracis, coupling its morphological description with molecular analysis carried out on ITS rDNA and COI mtDNA sequences.
Résumé
Les Clinostomidae sont des digènes caractérisés par une histoire taxonomique complexe, constamment en cours de révision sur la base d’analyses morphologiques et moléculaires. Parmi les 14 espèces considérées comme valides, Clinostomum phalacrocoracis n’a été bien décrit qu’au stade adulte alors que la morphologie de la métacercaire n’a été rapportée qu’une seule fois. Pendant une enquête parasitologique réalisée sur 262 cichlidés sauvages prélevés dans le Lac de Tibériade (Israël), des métacercaires rapportées à C. phalacrocoracis ont été trouvées dans 18 poissons. Dans cette étude, nous présentons pour la première fois cette espèce de Clinostomidae chez les poissons sauvages en provenance d’Israël et redécrivons la métacercaire de Clinostomum phalacrocoracis, en associant sa description morphologique à une analyse moléculaire réalisée sur des séquences ITS (ADNr) et COI (ADNmt).
