Foamy-like endogenous retroviruses are extensive and abundant in teleosts
Recent discoveries indicate that the foamy virus (FV) (Spumavirus) ancestor may have been among the first retroviruses to appear during the evolution of vertebrates, demonstrated by foamy endogenous retroviruses present within deeply divergent hosts including mammals, coelacanth, and ray-finned fish. If they indeed existed in ancient marine environments hundreds of millions of years ago, signif...
متن کاملFurther characterization of equine foamy virus reveals unusual features among the foamy viruses.
Foamy viruses (FVs) are nonpathogenic, widely spread complex retroviruses which have been isolated in nonhuman primates, cattle, cats, and more recently in horses. The equine foamy virus (EFV) was isolated from healthy horses and was characterized by molecular cloning and nucleotide sequence analysis. Here, to further characterize this new FV isolate, the location of the transcriptional cap and...
متن کاملEndogenous Viral Sequences from the Cape Golden Mole (Chrysochloris asiatica) Reveal the Presence of Foamy Viruses in All Major Placental Mammal Clades
Endogenous retroviruses provide important insights into the deep history of this viral lineage. Endogenous foamy viruses are thought to be very rare and only a few cases have been identified to date. Here we report a novel endogenous foamy virus (CaEFV) within the genome of the Cape golden mole (Chrysochloris asiatica). The identification of CaEFV reveals the presence of foamy virus in the plac...
متن کاملCross-species transmissions of simian retroviruses in Africa and risk for human health.
See page 932 Emerging zoonotic diseases are among the most important public-health threats facing humanity. One of the major examples is the AIDS epidemic which emerged in the 1980s as a result of cross-species transmissions of simian immunodeficiency viruses (SIVs) to human beings several decades earlier. As with HIV, other retroviruses (such as human T-lymphotropic viruses 1 and 2) are also o...
متن کاملAn Endogenous Foamy-like Viral Element in the Coelacanth Genome
Little is known about the origin and long-term evolutionary mode of retroviruses. Retroviruses can integrate into their hosts' genomes, providing a molecular fossil record for studying their deep history. Here we report the discovery of an endogenous foamy virus-like element, which we designate 'coelacanth endogenous foamy-like virus' (CoeEFV), within the genome of the coelacanth (Latimeria cha...
