| Description | Monogenean parasites of four goby species (Proterorhinus marmoratus, Neogobius fluviatilis, N. kessleri and N. melanostomus) were studied in Bulgarian and Slovak part of the Danube River (Europe), presenting both native and non-native area of Neogobius fishes distribution. Four Gyrodactylus species were identified from N. kessleri and N. melanostomus. The most dominant species parasitizing N. kessleri was Gyrodactylus proterorhini that was also only the species recorded from P. marmoratus. No significant differences in morphology were found in G. proterorhini from N. kessleri and P. marmoratus. Partial ITS sequences were obtained for G. proterorhini from N. kessleri and P. marmoratus. Sequence comparison revealed differences of 1.4% between parasite specimens collected from different host species. This result might suggest finding of a new cryptic species of Gyrodactylus specific for N. kessleri or might describe great population variability of G. proterorhini from non-generic host species. No parasites were found in N. fluviatilis. |
