Phylogenetic tree based on the hexon gene of avian adenoviruses, including the FAdV-11 of this study (designated with black circles) (sequence FAdV/IRIBHG obtained from an IBH outbreak in the broiler flock of the same source located in the north of Iran). Clustal W alignment was performed for a segment corresponding to nucleotides 18,632-19,251 of the complete genome of CELO (GenBank Accession No. U46993). Reference strains are bold and numbers in parentheses indicate serotypes for the respective reference strains. Representatives of the genera Atadenovirus (DAdV-1) and Siadenovirus (TAdV-3) were used as outliers. FAdV-11 associated subclusters are shown by Roman numerals (I-III)
