picornavirus
Noun: A picornavirus is a member of a large family of very small, non-enveloped viruses. Their genetic material is composed of single-stranded RNA, and they are protected by a protein shell called a capsid. This family includes many significant pathogens affecting humans and animals.
The word "picornavirus" is used as a countable noun to refer to any virus belonging to this specific taxonomic family (Picornaviridae). It is most commonly found in scientific, medical, and veterinary contexts. * Researchers have identified a new picornavirus in bats. * The common cold is often caused by a picornavirus such as rhinovirus. * Poliovirus, a dangerous picornavirus, has been largely eradicated through vaccination.
- As a modifier: The term is frequently used attributively (like an adjective) to describe related nouns (e.g., picornavirus infection, picornavirus genome, picornavirus research).
- The outbreak was due to a picornavirus infection.
- Taxonomic context: In virology, "Picornaviridae" is the formal family name, and "picornavirus" is the common name for any member of this family.
- Picornaviridae (noun, plural): The scientific family name for all picornaviruses.
- Non-enveloped virus (noun): A general term for viruses, like picornaviruses, that lack a lipid bilayer envelope.
- Enterovirus, Rhinovirus, Hepatovirus (nouns): Genera within the Picornaviridae family that include specific pathogens like poliovirus (enterovirus), common cold viruses (rhinovirus), and hepatitis A virus (hepatovirus).
There is no direct single-word synonym. The closest descriptive phrases are: * Single-stranded RNA virus (but this describes a much broader category). * Small, non-enveloped virus (a general physical description).
- Positive-sense RNA virus: A technical description of the viral genome type found in picornaviruses, meaning their RNA can be directly translated into protein by a host cell.
- ICTV classification: Refers to the International Committee on Taxonomy of Viruses, which defines and names virus families like Picornaviridae.

a group of single-strand RNA viruses with a protein coat
