Sannadkii 1962, André Lwoff, Robert Horne, iyo Paul Tournier waxay ahaayeen kuwii ugu horreeyay ee soo saara hab lagu kala saaro fayrasyada, oo ku saleysan nidaamka kala sarreeya ee Linnaean. Nidaamkani wuxuu ku salaysnaa kala soocida phylum, class, order, family, genus, iyo species. Fayrasyada waxaa loo kala saaray si waafaqsan sifooyinka ay wadaagaan (ma aha kuwa ay hayaan) iyo nooca nucleic acid ee ka kooban genomeskooda. Sanadkii 1966-kii, waxaa la aasaasay Guddiga Caalamiga ah ee Taxonomy of Viruses (ICTV). Nidaamka ay soo jeediyeen Lwoff, Horne iyo Tournier marnaba si buuxda uma aqbalin ICTV maxaa yeelay fayrasyada yar yar ee genome-ka iyo heerkooda sare ee isbeddelka waxay ku adkeynayaan go'aaminta awoowayaashood si aan kala sooc lahayn. Sidaa awgeed, kala soocida Baltimore waxaa loo isticmaalaa in lagu buuxiyo kala-soocida dhaqameed ee dhaqameed.  Su'aal: Sidee bay fayrasyada magac ugu yeeshaan ugana soo koobaan?
