Human T-lymphotropic virus type-1 (HTLV-1) infection is associated with adult T-cell leukemia/lymphoma (ATL). Tropical spastic paraparesis/HTLV-1-associated myelopathy (PET/HAM) is involved in the development of autoimmune diseases including Rheumatoid Arthritis (RA), Systemic Lupus Erythematosus (SLE), and Sjögren's Syndrome (SS). The development of HTLV-1-driven autoimmunity is hypothesized t...

INTRODUCTION We report the first known case of human T-lymphotropic virus type I associated myelopathy/tropical spastic paraparesis in an Australian Caucasian, a disease reported in Aboriginal and immigrant populations where the virus is often endemic. CASE PRESENTATION A 41-year-old Caucasian Australian man had a 3-year background of progressive functional decline from a myelopathy with spas...

Serological inspection of Simian T-lymphotropic Virus Type 1 was conducted for a wild colony of Macaca fuscata, which was captured in the middle Honshu, Japan. The increase of positive rate after the juvenile stage with the positive rate reaching 100% (or 35/35) in youngster and adult stages, was observed. This finding suggests that, in contrast with human T-lymphotropic Virus Type 1, horizonta...

background human t-cell lymphotropic virus types ι and ιι (htlv-ι and htlv-ii) are deltaretroviruses which may cause leukemia, lymphoma and htlv-associated myelopathy/tropical spastic paraparesis (ham/tsp). in addition, htlv-1 may be related to thalassemia and hemophilia cases after blood transfusion. objectives the aim of this study was evaluation of the prevalence of htlvs in patients with he...

objective: the aim of this study was to investigate the existence of human t-lymphotropic virus type 1 (htlv-1) in subgingival plaque of htlv-1 seropositive pa-tients. materials and methods: a total of 18 patients including 13 females and fivemales, with a mean age of 37 years participated in this descriptive study. half of them were htlv-1 carriers and the others were in htlv-1 associated myel...

We have isolated and characterised two divergent simian T-lymphotropic viruses (STLV), not belonging to the established human and simian T-lymphotropic virus lineages HTLV-1/STLV-1 and HTLV-2. STLV-L, from an Eritrean sacred baboon (Papio hamadryas), has been typed as a third type of simian T-lymphotropic virus, distinct from HTLV-1/STLV-1 and HTLV-2. The other virus, isolated from Congolese bo...
