The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
Genome (Zylberberg et al., 2016): 7,653 nt (5′-UTR: 788 nt; ORF: 6,780 nt; 3′-UTR: 85 nt). The location of the cre has not been identified.
The deduced polyprotein is of 2,260 aa. The genome encodes no L protein. 1AB remains uncleaved. The function of the 2A protein is unknown.
No virus has been isolated. Viral RNA has been detected in tissue samples (mandible) of diseased black-capped chickadees (Poecile atricapillus) in Anchorage and the Matanuska-Sustna Valley, Alaska, USA. The virus is suspected to cause the avian keratin disorder (AKD).
Poecivirus: refers to the host Poecile atricapillus (black-capped chickadee).
