Avian adenovirus

Aviadenovirus are viruses that affect birds; they represent one of four genera of the family Adenoviridae, the others being Mastadenovirus, Atadenovirus and Siadenovirus.

They are class I, non-enveloped, icosahedral viruses that are 74–80 nm in diameter, having a double stranded DNA genome of approximately 26–45 kilo–base pairs (kbp) and a guanine/cytosine content of 53–59%.

Naturally acquired aviadenovirus diseases include enteritis, splenitis, inclusion body hepatitis, bronchitis, pulmonary congestion ventriculitis, pancreatitis, oedema and abnormal reproduction (egg drop syndrome), depending on the species of bird infected.

Diagnosis of aviadenovirus is the same as for all adenoviruses, by viral isolation and serotyping also ELISA assay.
