Extract
Human T-cell lymphotropic virus type-1 (HTLV-I) is a recently recognized retrovirus identified as the cause of adult T-cell leukemia-lymphoma (ATLL) and HTLV-I-associated myelopathy (TSPI HAM). HTLV-I, a member of the Retroviridae family of viruses, was first described in 1980 after the isolation of the virus from a patient with a T-cell lymphoma. These pathogenic retroviruses are typically divided into the Oncovirinae and Lentivirinae. The oncovirus group, including HTLV-I, HTLV-II and bovine leukemia virus (BLV), is generally associated with tumors. The lentiviruses are associated with immune deficiency and/or neurologic disease, and include agents such as the visna virus of sheep and the human immunodeficiency virus type-1 and -2 HIV-1 and HIV-2).
