The env sequence obtained from the FeLV infections of jaguarundis #1 and #4 [KR349469] clustered with the highest identity with the FeLV-FAIDS and FeLV-3281 strains, which represent members of a highly conserved group of horizontally transmitted, minimally pathogenic FeLV-A present in all naturally occurring infections in domestic cats. Here, ERVW-1 is linked to infection.
