Background: Bovine leukaemia virus (BLV) is the primary cause of enzootic bovine leukaemia which belongs to the HTLV/BLV group of oncogenic retroviruses including Human T-cell leukaemia virus types 1, 2, and 3 and simian T-lymphotropic virus. Due to daily consumption of milk, meat and other dairy by-products, a possible role in appearing human cancers can be assumed for BLV. Materials and Metho...

The Brazilian Ministry of Health recommends the performance of serological tests in patients with clinical signs of Sexually Transmitted Diseases. However, data are lacking to affirm the necessity of testing these patients for human T-lymphotropic virus type 1 or type 2. This is a cross-sectional study with 120 patients seen at the Sexually Transmitted Diseases unit of the Sanitary Dermatology ...

The type C retrovirus simian T-lymphotropic virus type III (STLV-III) has been isolated recently from immunodeficient macaque monkeys at the New England Regional Primate Research Center. The present studies were done to define the in vitro growth characteristics of this agent. STLV-III replicates efficiently in interleukin 2-dependent T-cell cultures of macaque peripheral blood lymphocytes (PBL...

The epidemiological characteristics of human T-cell lymphotropic virus type I infection in Taiwan have been explored by an island-wide community-based survey, which was carried out among residents in 19 townships and metropolitan precincts randomly selected through stratified sampling. Serum specimens of 7278 healthy subjects were screened by enzyme-linked immunosorbent assay and confirmed by W...

Introduction The discovery in 1980 of the first human retrovirus (1), the human T-lymphotropic virus type 1 (HTLV-I), inaugurated a new era in human pathology. Two conditions were promptly associated with this retroviral infection (2): adult T-cell leukemia/lymphoma (ATLL) and tropical spastic paraparesis (TSP). Thus, this discovery solved a longlasting enigma in tropical medicine, the cause of...
