| sarcoma virus, feline | A species of mammalian type c retroviruses (retroviruses type c, mammalian) isolated from fibrosarcoma in cats. The virus is actually a recombinant feline leukaemia virus (felv) where part of the genome has been replaced by cellular oncogenes. It is unique to individuals and not transmitted naturally to other cats. Fesv is replication defective and requires felv to reproduce. (12 Dec 1998) |

| herpes virus, kaposi sarcoma-associated | Species of an unnamed genus, subfamily gammaherpesvirinae, isolated from patients with aids-related and "classical" kaposi sarcoma. The sequences suggest this is a new human herpes virus, unofficially identified as human herpes virus-8 (hhv-8). (12 Dec 1998) |
