Description
Summary:[Display omitted] •Sacbrood virus structural polyprotein and non-structural RNA dependent RNA polymerase were analysed.•Based on these genes, Turkish SBV strains differed from those in other geographic areas.•Sacbrood virus varies genetically according to host affiliation and geographic origin. Sacbrood virus (SBV) is one of the most damaging viruses in honey bee colonies. Genetic differences among sacbrood viruses detected in honey bees in different locales have been reported in previous studies. The aim of this study was to construct phylogenetic trees based on the structural polyprotein and non-structural RNA dependent RNA polymerase gene regions and to make a molecular characterization of the Tur/Bur/Sac01 and Tur/Bur/Sac02 strains identified in Apis mellifera in Turkey. As a result of the study, the tree based on the structural polyprotein region separated into four lineages: Tur/Bur/Sac01 and Tur/Bur/Sac02 were in the same branch as the Turkish sacbrood virus strains identified in previous studies and formed the Turkish clade. Strains isolated from adjacent geographical areas were in the same clade in this tree. The phylogenetic tree based on the non-structural RNA dependent RNA polymerase gene region divides into two main branches, reflecting host affiliation: Apis cerana and A. mellifera. Strains formed clusters based on their geographic distribution and host affiliation. The Tur/Bur/Sac01 and Tur/Bur/Sac02 strains formed a separate cluster among the European strains. Sacbrood viruses from Turkey were genetically different from SBV strains detected in other countries and in A. cerana.
