Phylogenetic analysis of the selected fowl adenoviruses (FAdVs) using nucleotide sequences encoding for the hexon gene. The data included Pakistani isolates, indicated with Black Square, and other already published FAdV strains retrieved from GenBank. FAdV strains are classified on species level e.g. species A, species B, species C, species D and species E. The evolutionary history was inferred using the Neighbor-Joining method. Numbers indicate the bootstrap values (1000 replicates). The analysis involved 42 nucleotide sequences.
