The genus Cardiovirus consists two species,
Encephalomyocarditis virus and
Theilovirus.
EMCV is represented by a single serotype of the
same name while the theiloviruses are comprised of
Theiler's murine
encephalomyelitis virus (TMEV), Vilyuisk human encephalomyelitis virus
(VHEV), Thera virus (TRV; isolated from rats),
Saffold virus (SAFV;
isolated from humans) 1-8.
The cardioviruses are most closely related to members of the genera
Senecavirus,
Aphthovirus and
Erbovirus and to the
recently recognised cosaviruses.
Below: Phylogenetic analysis
of the P1 capsid-coding region of the cardioviruses.
Key:
EMCV, encephalomyocarditis virus
