− | Canine adenovirus 1 (CAV1) is a member of the Adenoviridae family. The Adenoviridae are a family of double-stranded DNA viruses which have an icosahedral nucleocapsid and have been isolated from many mammals and birds. However, only a small number of Adenoviridae cause significant veterinary disease, one of these being canine adenovirus 1.
| + | CAV-1 is a member of the Adenoviridae family, a group 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. Canine adenovirus 1 is a Mastadenovirus. |
− | Classification
| + | |
− | This family originally consisted of only two genera, Mastadenovirus, which infect mammals, and Aviadenovirus, which infect birds. There are also several as yet unassigned and recently assigned viruses in the family.
| |
− | Mastadenovirus
| |
− | This genus consists of 20 virus species that infect mammals including canine, equine, bovine, ovine and porcine adenoviruses. All 20 species share a common antigen. Important diseases are infectious canine hepatitis, canine adenovirus 2 infection, and equine adenovirus A infection.
| |
− | Aviadenovirus
| |
− | This genus includes the viruses of inclusion body hepatitis, quail bronchitis, marble spleen disease and a number of adenoviruses of poultry and birds that are not associated with significant diseases. Members of the genus share a common antigen.
| |
− | Previously Unassigned Adenoviruses
| |
− | Included in this category are the viruses that have recently (2002) been placed in the genera Atadenovirus and Siadenovirus. These viruses include the egg drop syndrome virus (Atadenovirus), turkey hemorrhagic enteritis (Siadenovirus), adenoviral splenomegaly of chickens (Atadenovirus) and ovine adenovirus 287 (Atadenovirus; of research interest, but of no disease significance) and some bovine adenovirus types 4 to 8 (Atadenovirus).
