Molecular characterisation of Neoparamoeba strains isolated from gills of Scophthalmus maximus.
Small subunit ribosomal RNA gene sequences were determined for 5 amoeba strains of the genus Neoparamoeba Page, 1987 that were isolated from gills of Scophthalmus maximus (Linnaeus, 1758). Phylogenetic analyses revealed that 2 of 5 morphologically indistinguishable strains clustered with 6 strains identified previously as N. pemaquidensis (Page, 1970). Three strains branched as a clade separate...
متن کاملEpizoic amoebae from the gills of turbot Scophthalmus maximus.
Species of amoebae belonging to the genera Platyamoeba Page, 1969, Vannella Bovee, 1965 and Flabellula Schaeffer, 1926 were found to accompany Paramoeba sp., the agent of amoebic gill disease (AGD), in clinically diseased turbots. The same community of epizoic gymnamoebae was found on the gills of turbots which revealed no gill abnormalities but slight behavioral signs indicative of suboptimal ...
متن کاملTurbot - Scophthalmus maximus
Distribution Th e turbot, Scophthalmus maximus, also called Psetta maxima (Scophthalmidae, Pleuronectiformes), is naturally distributed in European waters, from Northeast Atlantic to the Arctic Circle (30o to 70oN; 23oW42oE). It occurs in the Baltic and in the Mediterranean, as well as in the Black Sea, where a subspecies Psetta maxima maeotica has been described (1). It also exists in the Sout...
متن کاملScophthalmus maximus L. larviculture
The aerobic bacterial flora in the gut of turbot larvae and their influence on larval survival was examined. Two turbot experiments were run with six replicates each time. Large variation, from 0% up to 44%, was observed in the survival percentage of turbot larvae. There was no correlation between the number of bacteria present in the gut of turbot larvae and the larval survival rate. During bo...
متن کاملPathogenicity of birnaviruses isolated from turbot (Scophthalmus maximus) : comparison with reference serotypes of IPNV
The pathogenicity of different birnavirus strains to turbot was determined by challenge experiments. The reference strains of IPNV (Sp, Ab and VR-299) were not pathogenic for turbot (Scophthalmus maximus). The Norwegian serotype (N1) and two selected birnavirus strains isolated from turbot and related to the Ab serotype of IPNV (TB-306 and TB-390) were virulent to different degrees for turbot a...
