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).

The family consists of four genera: Mastadenovirus, Aviadenovirus, Atadenovirus and Siadenovirus. The Mastadenoviruses include Canine Adenovirus 1 (CAV-1) and Canine Adenovirus 2 (CAV-2), which cause [[Infectious Canine Hepatitis]] and respiratory disease respectively. Equine Adenovirus A (also known as Equine Adenovirus 1) is also a Mastadenovirus and causes respiratory signs in horses.

 

Aviadenoviruses are viruses of poultry and other birds. The genus contains inclusion body hepatitis, quail bronchitis and other avian viruses not associated with a particular disease. The Atadenovirus and Siadenovirus genera contain viruses that until recently were unassigned. These include egg drop syndrome virus and adenoviral splenomegaly of chickens as Atadenoviruses, and turkey haemorrhagic enteritis as a Siadenovirus.
