FELINE IMMUNODEFICIENCY VIRUS AETIOLOGY


Feline immunodeficiency virus (FIV) is a lentivirus (retrovirus family). It is related structurally, biochemically and by nucleotide sequence to human immunodeficiency virus (HIV), the cause of AIDS in man, and infection of cats is also associated with eventual development of clinically apparent immunodeficiency. FIV does not infect human cells, and repeated surveys have shown no evidence of human infection with FIV.
