Distinct epidemiological profiles of porcine circovirus 3 and fox circovirus in Canadian foxes (Vulpes spp.)
Circoviruses (genus Circovirus, family Circoviridae) are ssDNA viruses that infect mammals, and they sometimes can transmit among different species. We investigated the distribution and diversity of porcine circovirus 3 (PCV-3, species Porcine circovirus 3) and fox circovirus (species Canine circovi...
