The species Anativirus
B consists of
a single serotype, known as quail picornavirus 1 or phacovirus 1.
Quail picornavirus 1, now named phacovirus A1
(PhV-A1), complete genome
sequence was deposited in the public databases on the 12-Sep-2011
(released on 15-11-2011); accession no.
(Pankovics et al., 2012). It appears to be most closely
related to the sapeloviruses.
A partial sequence from chickens with runting-stunting
syndrome (Kim et al., unpub.) is most closely related to
PhV-A1. It was named by the authors as chicken
picornavirus HK-2014 along with two partial sequences of a virus
most closely related to
chicken megrivirus. This sequence (partial 3CD) has 70% nt & 81%
aa identity to PhV-A1.
Related viruses have been identified in chickens in Hungary and the
USA (Boros et al., 2016).
