Abstract
While various haemoparasites have been reported from anuran hosts, this study provides the first published record of dactylosomatid parasites (Dactylosomatidae Jakowska & Nigrelli, 1955 emend. Levine, 1971) in frogs from Slovakia. Of the 239 anurans screened for apicomplexans, 67 individuals belonging to three species of water frogs, Pelophylax esculentus (Linnaeus, 1758), P. ridibundus (Pallas, 1771), and P. lessonae (Camerano, 1882) were found to be infected with haemogregarines of the genus Dactylosoma Labbé, 1894. Our results demonstrate that the haemogregarine found in all three species of water frogs, collected from three different localities in western Slovakia, represents a single taxon that morphologically resembles the type species, Dactylosoma ranarum (Kruse, 1890). Based on comprehensive morphometric, morphological, and molecular data from newly collected isolates from Pelophylax frogs, including the type host, we provide an integrative assessment of Dactylosoma cf. ranarum. We also conducted molecular screening of dipterans collected from the study sites, which could serve as potential vectors of the parasite, but no representatives of Dactylosoma were detected in any of the examined specimens.
Résumé
Bien que divers hémoparasites aient été signalés chez des hôtes anoures, cette étude fournit la première mention publiée de dactylosomatidés (Dactylosomatidae Jakowska & Nigrelli, 1955 emend. Levine, 1971) parasites de grenouilles de Slovaquie. Parmi les 239 anoures examinés pour la recherche d'apicomplexes, 67 individus appartenant à trois espèces de grenouilles, Pelophylax esculentus (Linnaeus, 1758), P. ridibundus (Pallas, 1771) et P. lessonae (Camerano, 1882) étaient infectés par des hémogrégarines du genre Dactylosoma Labbé, 1894. Nos résultats démontrent que l'hémogrégarine présente chez ces trois espèces de grenouilles, collectées dans trois localités différentes de l'ouest de la Slovaquie, représente un taxon unique qui ressemble morphologiquement, à Dactylosoma ranarum (Kruse, 1890). À partir de données morphométriques, morphologiques et moléculaires exhaustives issues d'isolats nouvellement collectés chez des grenouilles du genre Pelophylax, y compris l'hôte-type, nous proposons une évaluation intégrative de Dactylosoma cf. ranarum. Nous avons également effectué un criblage moléculaire des diptères collectés sur les sites d'étude, qui pourraient servir de vecteurs potentiels du parasite, mais aucun représentant de Dactylosoma n'a été détecté dans aucun des spécimens examinés.
