Simian T-lymphotropic virus 1

**Definition:** A strain of PRIMATE T-LYMPHOTROPIC VIRUS 2, closely related to the human HTLV-1 virus. The clinical, hematological, and histopathological characteristics of the disease in STLV-infected monkeys are very similar to those of human adult T-cell leukemia. Subgroups include the African green monkey subtype (STLV-I-AGM), for which the nucleotide sequence is 95% homologous with that of HUMAN T-LYMPHOTROPIC VIRUS 1, and the Asian rhesus macaque subtype (STLV-I-MM), for which the nucleotide sequence is 90% homologous with that of HUMAN T-LYMPHOTROPIC VIRUS 1.
