The genus Cardiovirus consists
six species,
Cardiovirus A
(formerly named Encephalomyocarditis virus),
Cardiovirus B
(formerly named Theilovirus) and
Cardiovirus C,
Cardiovirus
D (Saffold virus),
Cardiovirus
E (red-backed
vole cardiovirus) and
Cardiovirus
F (grey-backed
vole cardiovirus)
Cardiovirus A is comprised of two serotypes of
encephalomyocarditis virus (EMCV). Cardiovirus B is comprised of
Theiler's murine
encephalomyelitis virus (TMEV), Vilyuisk human encephalomyelitis virus
(VHEV), Thera virus (TRV;
isolated from rats).
Cardiovirus C is comprised of Boone cardiovirus 1 and 2. Note: due to the lack of complete polyprotein-coding
sequences for genet fecal
theilovirus and marmot
cardiovirus, proposals as new species were rejected by
the ICTV.
The cardioviruses are most closely related to members of the genera ,
Aphthovirus,
Cosavirus,
Erbovirus and
Senecavirus.
