英文摘要: Abstract(#br)Koala retrovirus (KoRV) is unique among endogenous retroviruses because its endogenization is still active. Two major KoRV subtypes, KoRV-A and B, have been described, and KoRV-B is associated with disease and poses a health threat to koalas. Here, we investigated the co-prevalence of KoRV-A and KoRV-B, detected by type-specific PCR and sequencing, and their impact on the health of koalas in three Japanese zoos. We also investigated KoRV proviral loads and found varying amounts of genomic DNA (gDNA) in peripheral blood mononuclear cells (PBMCs). We found that 100% of the koalas examined were infected with KoRV-A and 60% (12/20) were coinfected with KoRV-B. The KoRV-A sequence was highly conserved, whereas the KoRV-B sequence varied among individuals. Interestingly, we...
