Adenoviridae are a group of double-stranded DNA viruses with an icosahedral nucleocapsid. Many Adenoviridae have been isolated from mammals and birds, but only a small number of these cause significant veterinary disease. The family consists of four genera: Mastadenovirus, Aviadenovirus, Atadenovirus and Siadenovirus. The Mastadenoviruses include Canine Adenovirus 1 (CAV-1), Canine Adenovirus 2 (CAV-2).
