Avian and serpentine endogenous foamy viruses, and new insights into the macroevolutionary history of foamy viruses.

ABSTRACT: This study reports and characterises two novel distinct lineages of foamy viruses (FVs) in the forms of endogenous retroviruses (ERVs). Several closely related elements were found in the genome of oriental stork (Ciconia boyciana) and other was found in the genome of spine-bellied sea snake (Hydrophis hardwickii), designated ERV-Spuma.N-Cbo (where 'N' runs from one to thirteen) and ERV-Spuma.1-Hha, respectively. This discovery of avian and serpentine endogenous FVs adds snakes, and perhaps more crucially, birds to the list of currently known hosts of FVs, in addition to mammals, reptiles, amphibians, and fish. This indicates that FVs are, or at least were, capable of infecting all major lineages of vertebrates. Moreover, together with other FVs, phylogenetic analyses showed t
