Abstract The current classification of animal viruses primarily relates to the virus molecular world, the genomic architecture and the corresponding host-cell infection cycle. This virus centered perspective does not make allowance for the precept that virus fitness hinges on the virus transmission success. Virus transmission reflects the infection-shedding-transmission dynamics and, with it, the organ system involvement and other, macroscopic dimensions of the host environment. This study examines the transmission ecology of the world main livestock viruses, 36 in total, belonging to eleven different families, and a mix of RNA, DNA and retroviruses. Viruses are virtually ranked in an outer- to inner-body fashion, based on the shifting organ system involvement and associated infection-shedding-transmission dynamics. As a next step, this ranking is disentangled with the aim to contrast two main host ecologies, poultry plus pig production and ruminant plus equine husbandry, as well as to create a distinction among the RNA, DNA and retroviruses, also ranked in an outer- to inner-body fashion. Spearman correlation reveals the matches among these various virus traits, as pertaining to the two host-ecologies, four infection-shedding-...Continue Reading
