Adenoviruses (AdVs) are member of the family Adenoviridae, non-enveloped with an icosahedral nucleocapsid containing double stranded DNA genome, divided into five genera: Atadenovirus, Aviadenovirus
, Ichtadenovirus, Mastadenovirus and Siadenovirus (Harrach et al., 2012).
AB303301) showed that RV1 was homologous to tree shrew adenovirus 1 (70.0% amino acid sequence identity), porcine adenovirus 5 (69.2%), canine adenovirus 1 (68.9%), human adenoviruses-3, -16, -21 and -50 (68.9%), and other viruses (>64.8%) in genus Mastadenovirus, but less homologous (46.7%-57.8%) to viruses in other genuses, Siadenovi rus, Aviadenovirus
, and Atadenovirus.
The gene sequence, excluding the primer sequence, was aligned with the Northern aplomado falcon (Falco femoralis) variant of the falcon adenovirus, the 12 fowl adenoviruses in the Aviadenovirus genus, and Sequencer 3.1.2 (Gene Codes Corporation, Ann Arbor, MI, USA).
Sequence analysis of the falcon adenovirus showed it to be an aviadenovirus with 2 genotypes, varying by 1.3% of their hexon protein.
The deaths of the female and male birds were attributed to the Aviadenovirus
and K.U.) with aviadenovirus specific primers of the hexon gene capable of detecting DNA from the 12 fowl adenovirus serotypes (former group I adenoviruses), (1-3) These assays failed to identify adenoviral DNA.
Adenoviruses are currently classified into 4 genera: Mastadenovirus, Aviadenovirus, Siadenovirus, and Atadenovirus.
