Genetic diversity of species Fowl aviadenovirus D and Fowl aviadenovirus E

Complete genomes of eight reference strains representing different serotypes within the species Fowl aviadenovirus D (FAdV-D) and Fowl aviadenovirus E (FAdV-E) were sequenced. The sequenced genomes of FAdV-D and FAdV-E members comprise 43 287 to 44 336  bp, and have a gene organization identical to that of an earlier sequenced FAdV-D member (strain A-2A). Highest diversity was noticed in the hexon and fiber genes and ORF19. All genomes sequenced in this study contain one fiber gene. Phylogenetic analyses and G+C content support the division of the genus Aviadenovirus into the currently recognized species. Our data also suggest that strain SR48 should be considered as FAdV-11 instead of FAdV-2 and similarly strain HG as FAdV-8b. The present results complete the list of genome sequences of reference strains representing all serotypes in species FAdV-D and FAdV-E.
