Definition of virion in English:

virion

noun ˈvɪrɪɒnˈvɪriɑn

Microbiology

The complete, infective form of a virus outside a host cell, with a core of RNA and a capsid.
〔微生物〕病毒粒子，毒粒，壳包核酸
Example sentencesExamples
- At the center of the virion is a protein capsid containing two identical, single strands of genomic RNA, plus essential reverse transcriptase enzymes, as well as some accessory molecules.
- However, the tubes may contain multiple virions, or capsids, like peas in a pod, or the linear arrangement of spores in neurospora filaments.
- It is probable that movement of poliovirions occurs through the interaction of the virions with the host cell actin similar to the mechanisms seen in some bacterial infections 10-12.
- A US research team examined the possibility that normal human oral keratinocytes might be directly infected by HIV or might convey infectious HIV virions to adjacent leucocytes.
- The humoral arm produces virus-neutralizing antibodies that, when fully effective, completely prevent virions from infecting new host cells.

Origin

1950s: from virus + -on.
