DOMAIN-SPECIFICITY. “While any cellular domain can be infected by a virus, no extant virus is known to traverse more than one domain. This domain-specific ecology of viruses underpins the current taxonomic paradigm of trifurcating viruses into eukaryotic, archaeal and bacterial categories, along with recent reappraisals of whether viruses constitute a fourth domain of life.”
