ConclusionComparisons of SD07LK1 sequence with that of the other Avian leukosis viruse strains, by using DNAstar software, demonstrated that the genes gag and pol of ALV-J were relatively conservative, the nucleotide identity of all the strains was over 95.0%. However, the gene env identity was only in the ranges between 88.6 and 94.0%.
