Avian leukosis virus is a contagious oncogenic virus that can infect various bird species. This virus is economically important in the poultry industry. The aim of this study was to identify molecular strains of leukosis virus circulating in duck farms in Mazandaran province. Freshly dead birds were necropsied and samples of tumor tissues were processed for molecular detection of avian tumorigenic viruses using polymerase chain reaction (PCR). At necropsy, diffuse and sometimes nodular enlargement of the internal organs and subscapular hemorrhage in the liver and spleen was noted. All three studied flocks were positive for infection with serogroup J of leukosis virus, while all samples were negative for involvement with reticuloendotheliosis and Marek’s disease viruses. Since leukosis is a serious threat to the poultry industry and currently does not have a vaccine or medicine, it is recommended to carry out periodic monitoring and analysis for the circulating strains of virus.
