The strains of adenoviruses were isolated from 356 birds with clinical form of Marek’s disease and coinfection with adenoviruses. A hexon gene fragment coding loop L1 of adenovirus strains was sequenced and obtained data were analysed with BLAST, Geneious 5.3, and MEGA5 software by comparison with nucleotide sequences of reference strains of fowl adenoviruses (FAdV-1 - FadV-12), two turkey adenoviruses, and two goose adenovirus strains. On this basis, serotypes of adenovirus strains were determined. Sequences of all adenovirus strains isolated from birds infected with Marek’s disease virus were classified into six serotypes representing four species. Mostly FAdV-7, FAdV2/11, and FAdV-8a serotypes were found.
