Histological and molecular studies of species of Myxobolus Bütschli, 1882 (Myxozoa: Myxosporea) in the gills of Abramis, Blicca and Vimba spp. (Cyprinidae), with the redescription of M. macrocapsularis Reuss, 1906 and M. bliccae Donec & Tozyyakova, 1984.

Abstract:

:Although Myxobolus spp. from cyprinid fishes are generally characterised by a strict host-specificity, this study has found that the breams Abramis brama (L.), Blicca bjoerkna (L.) and Vimba vimba (L.) may be infected by the same Myxobolus spp. It is demonstrated that M. macrocapsularis Reuss, 1906, a parasite of the gill filaments of B. bjoerkna, can also infect A. brama. In the same way, M. bliccae Donec & Tozyyakova, 1984, also a parasite of B. bjoerkna, can also occur in V. vimba. The molecular sequences of M. macrocapsularis spores from B. bjoerkna and A. brama were 100% identical. Two of the 18S rDNA sequences of three replicate samples of M. bliccae from B. bjoerkna were 100% identical, whereas the third sequence exhibited a 99.7% similarity with sequences from V. vimba. M. bliccae sequences of spores collected from V. vimba showed a 99.8% similarity to the first two isolates and 99.6% to the third. Data obtained by morphological, histological and molecular biological methods all suggest that Myxobolus spp., known for their strict host-specificity, may sometimes infect several closely related cyprinids.
