FeLV-B is a recombinant virus; a unique FeLV-B is created each time FeLV-A recombines with enFeLV SU gp70 sequences already present in the cat's cellular DNA FeLV-C arises from FeLV-A through both mutation and recombination with enFeLV sequences. Once again, only FeLV is transmitted contagiously among cats. All FeLV-infected cats are infected with FeLV-A, but not necessarily with FeLV-B and/or FeLV-C. Ong
