||The genus Sapelovirus consists of two
species, Sapelovirus A (formerly named Porcine sapelovirus)
Sapelovirus B (formerly named Simian sapelovirus).
A third species (Avian
sapelovirus) has been renamed
Anativirus A and
moved to a new genus Anativirus).
The name Sapelovirus
was orginally derived from Simian, Avian and
Porcine Entero-Like viruses; however, since avian
sapelovirus has moved, it could be described as being derived from
Simian And Porcine
The two sapelovirus species may be distinguished
by i) different host species; and ii) sequence diversity. For
example in the VP1 gene there is less than 50% amino acid identity
between the species. The simian sapeloviruses
(which probably belong to three [sero]types) have probably undergone
some complicated recombination events as can be seen from a
comparison of sequences in different genome regions.
In 2011, two new sapeloviruses were discovered in
California sea lions and tentatively named
California sea lion
sapelovirus 1 and 2 (Li et al., 2011).
A partial sequence of a
murine sapelovirus has recently
been reported (Phan et al., unpublished).
