Phylogenetic relationships of Brazilian FAdV-I sequences from chickens presented enteric problems, impairment, malabsorption diseases, hydropericardium and hepatitis in comparison to isolates from different countries. The tree was inferred based on alignments of partial hexon gene segment L1 and adjacent P1, using the Maximum Likelihood statistical method included in the MEGA 5 software. Numbers along the branches refer to bootstrap value for 1000 replicates. The scale bar represents the number of substitutions per site. Highlighted names represent the sequences used in this study, and letters A to E represent fowl adenovirus groups. DAdV-2 Duck adenovirus 2 sequence was employed as the out-group
