VIRAL HEMORRHAGIC SEPTICEMIA VIRUS ISOLATES FROM FARMED TROUT IN BULGARIA: ETIOLOGY AND MOLECULAR CHARACTERIZATION

V. Chikova, E. Mileva

Abstract: Viral haemorrhagic septicemia (VHS) in trout is an acute viral disease listed by the OIE. In Bulgaria, the virus has also been established repeatedly. Sequence analysis on the phylogeny of the strains allow assigning to two different genotypes. One of them from Scandinavic region – unrepresentative but apparently market performance. Molecular methods developed in the Bulgarian NRL for fish diseases, allowing fast and accurate diagnosis, tracing the origins of the isolated strains and the ways of their penetration in the country.
