The species Boosepivirus bebovi
(formerly named Boosepivirus B)
contains two genotypes, boosipivirus B1 and B2.
Boosipivirus B1 was originally called bovine picornavirus Japan (BPV-J) group B.
Five complete (or nearly complete) genome
sequences were detected in cattle faeces collected in Hokkaido
Prefecture in 2009. There were most closely related to the sapelo-like viruses
bat picornavirus 1-2,
bat picornavirus 3,
feline picornavirus 1 and
canine picornavirus 1 (Nagai et al., 2015).
The five bovine picornaviruses fell into two genetic groups, which I
have labelled A (Boosepivirus
A) and B (Boosepivirus B):
A) Bo-11-39/2009/JPN (LC006971).
B) Bo-12-3/2009/JPN (LC036579),
Bo-12-7/2009/JPN (LC036580),
Bo-12-11/2009/JPN (LC036581)
and Bo-12-38/2009/JPN (LC036582).
Their polyprotein sequences share only about 52% aa identity,
suggesting that they may represent two distinct virus species.
