An endogenous foamy virus in the aye-aye (Daubentonia madagascariensis)

We report the discovery and analysis of an endogenous foamy virus (PSFVaye) within the genome of the aye-aye (Daubentonia madagascariensis), a strepsirrhine primate from Madagascar. Phylogenetic analyses indicate that PSFVaye is divergent from all known simian foamy viruses, suggesting an association between foamy viruses and primates since the haplorrhine-strepsirrhine split. The discovery of PSFVaye indicates that primate foamy virus might be more broadly distributed than previously thought.
