Avian adenoviruses

Adenoviruses are non-enveloped double-stranded DNA viruses which commonly affect poultry and wild bird worldwide. In many instances, healthy birds are infected without showing signs of disease, until a stressful event or injury or sickness, in which they become opportunistic pathogens.

Genus Aviadenovirus Group I Avian adenoviruses: There are five virus species--A, B, C, D, and E and 12 serotypes:

• Fowl adenovirus A, serotype Fowl adenovirus 1 (FAdV-1)
• Fowl adenovirus B, serotype Fowl adenovirus 5 (FAdV-5)
• Fowl adenovirus C, serotype Fowl adenovirus 4 (FAdV-4)
• Fowl adenovirus 10 (FAdV-10)
• Fowl adenovirus D, serotype adenovirus 2 (FAdV-2)
• Fowl adenovirus 3 (FAdV-3)
• Fowl adenovirus 9 (FAdV-9)
• Fowl adenovirus 11 (FAdV-11)
• Fowl adenovirus E, serotype Fowl adenovirus 6 (FAdV-6)
• Fowl adenovirus 7 (FAdV-7)
• Fowl adenovirus 8a (FAdV-8a)
• Fowl adenovirus 8b (FAdV-8b)
• Duck adenovirus 2 (DAdV)
• Pigeon adenovirus (PiAdV)
• Turkey adenovirus 1, 2 (TAdV)

Genus Siadenovirus Group II Avian adenoviruses:

• Hemorrhagic enteritis virus (turkeys)
• Marble spleen disease (pheasants)
• AASV (chickens)

Genus Atadenovirus Group III Avian Adenoviruses:

• Egg drop syndrome

Associated diseases:

• Inclusion Body Hepatitis (IBH)
• Hydropericardium Syndrome
• Gizzard Erosions

Disinfectants: Adenoviruses are resistant to lipid solvents, sodium deoxycholate, trypsin, 2% phenol and 50% alcohol.

Transmission: Adenoviruses are transmitted vertically, and chicks hatched from infected eggs can shed the virus in their feces after they hatch.
