title: [Molecular-genetic analysis of the field isolates of avian leucosis viruses in the Russian Federation].
abstract: Results of monitoring of different subtypes of avian leukosis virus (ALV) from commercial poultry farms in 14 regions of Russian Federation were discussed. Only three regions were found to be negative. ALV was detected in other 11 regions in 46-64% cases (for different regions). The phylogenetic analysis of the genomes for the 12 field isolates of ALV was carried out in different regions of Russian Federation. The isolates belong to different subtypes of the virus and form two large groups. The genomic differences between Russian and foreign isolates within each group range from 5% to 10%.
