Phylogenic analysis of FAdV-4 isolates. a By phylogenic analysis based on the genomic sequences with ClustalW method, the 5 strains belong to species C FAdV serotype 4. b The FAdV-4 strains were divided into two genotypes. All the recent virulent strains fell into genotype 2, whereas three non-pathogenic strains, B1–7, ON1 and KR5 belong to genotype 1. c Comparison of the genomic sequences showed the mutations or deletions might be related to virulence. The brakets represent amino acids
