Genera "Host Range"

Mammalian type B oncovirus group "Limited to a few exogenous, vertically-transmitted (via milk) and endogenous viruses of mice. Associated with mammary carcinoma and T-lymphoma. Related endogenous sequences have been found in other rodents and primates. No oncogene-containing members are known." (B72)
MLV-related viruses (Mammalian type C retrovirus group) "Widespread exogenous vertically and horizontally transmitted and endogenous viruses found in many groups of mammals. The reticuloendotheliosis group comprises a few isolates from birds, with no known corresponding endogenous relatives. Related endogenous sequences are found in mammals. Associated with a variety of diseases including malignancies, immunosuppression, neurological disorders and others. Many oncogene-containing members of the mammalian and reticuloendotheliosis virus group have been isolated." (B72)
Type D retrovirus group "Several isolates of exogenous, horizontally transmitted and endogenous viruses of new and old world primate species. Exogenous virus isolates associated with immunodeficiency disease. No oncogene-containing members are known" (B72)
Avian type C retrovirus group (ALV-related viruses) "Widespread exogenous vertically and horizontally transmitted and endogenous viruses found in chickens and some other birds. Distantly related endogenous sequences are found in birds and mammals. Associated with malignancies and some other diseases such as wasting, osteoporosis. Many oncogene-containing members of this group have been isolated." (B72)
Spumavirus: Foamy virus group "Widespread exogenous viruses found in many group of mammals. No related endogenous viruses are known. Although many isolates cause characteristic "foamy" cytopathology in cell culture, no associated diseases have been described. No oncogene-containing members of this group have been isolated." (B72)
HTLV-BLV group "Exogenous horizontally-transmitted viruses found in a few groups of mammals. No related endogenous viruses are known. Associated with B or adult T cell leukemia/lymphoma with a very long latency and less than 100% incidence. No oncogene-containing members of this group have been isolated." (B72)
Lentivirus: lentivirus group Exogenous horizontally and vertically-transmitted viruses found in humans and many other groups of mammals. No related endogenous viruses are known. Associated with a variety of diseases including immunodeficiencies, neurological disorders, arthritis and others. No oncogene-containing members of this group have been isolated. (B72)
