Cardiovirus
genus of viruses
Cardiovirus are a group of viruses within order Picornavirales, family Picornaviridae. Vertebrates serve as natural hosts for these viruses.
Taxonomy
The genus contains the following species:
Cardiovirus dhusarah (Cardiovirus F)
Cardiovirus ranori (Cardiovirus C)
Cardiovirus rudhira (Cardiovirus E)
Cardiovirus rueckerti (Cardiovirus A), Encephalomyocarditis virus
Cardiovirus saffoldi (Cardiovirus D), Saffold virus
Cardiovirus theileri (Cardiovirus B), which contains Theiler's murine encephalomyelitis virus
Structure
Cardioviruses are single-stranded RNA, non-enveloped viruses with icosahedral or spherical geometries, and a T=pseudo3 icosahedral capsid protein geometry. The diameter is around 30 nm. Genomes are linear and non-segmented, around 7.8 kb in length. The T=pseudo3 icosahedral capsid of Cadiovirus is made of 60 protomers, each of which contains 4 polypeptides: VP1, VP2, VP3, and VP4. Inside the capsid of the virus there is a single linear, positive single-stranded RNA. On both the 3' and 5' ends of the genome there are untranslated regions. These untranslated regions of genome are important for the DNA replication, with the untranslated region on the 5' side being the location of internal ribosomal entry site (IRES).
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the virus to host receptors, which mediates endocytosis.
This brief starts where responsible research should: with the source description of “Cardiovirus” as genus of viruses. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of viruses. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Oct 2, 2025. The linked authority identifier is Q5038746. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “Cardiovirus”, its source revision and the description used here.
- Expand the search: follow Cardiovirus primary sources, Cardiovirus archive and Cardiovirus research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
Questions for further research
- Which source most directly establishes the central claim about “Cardiovirus”?
- Is the terminology current, historical or disputed?
- Which observation, specimen, dataset or publication supports the account?
