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. However, the tubes may contain multiple virions, or capsids, like peas in a pod, or the linear arrangement of spores in neurospora filaments. Origin 1950s: from virus + -on.
