Lymphotropic strains of human immunodeficiency virus type 1 (HIV-1), including HTLV-IIIB, replicate poorly in macrophages. We have shown previously that lymphotropic HIV-1 fuses equally well with T lymphocytes and macrophages (M. J. Potash, M. Zeira, Z.-B. Huang, T. Pearce, E. Eden, H. Gendelman, and D. J. Volsky, Virology 188:864-868, 1992), suggesting that events in the virus life cycle follo...

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...

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...

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...

discussion bladder over-distention and spontaneous bladder rupture, although very rare in ham/tsp, should be considered in a differential diagnosis of bladder rupture, especially in patients with a history of htlv1. introduction spontaneous bladder rupture is a rare manifestation of hyporeflexic bladder due to ham/tsp( human t-cell lymphotropic virus type 1 (htlv1) associated myelopathy/tropica...

A new strain of simian T-lymphotropic virus type 1 in blood samples from a chimpanzee that lived in the tropical rainforest of Ivory Coast is described. The sequence obtained from the long terminal repeat region of the genome is significantly divergent from all known human and nonhuman primate T-lymphotropic virus type 1 strains (963% homology to the closest related strains from Central African...

Herpesvirus sylvilagus is a lymphotropic (type gamma) herpesvirus of cottontail rabbits (Sylvilagus floridanus). Analysis of virion DNA of herpesvirus sylvilagus has revealed that the genome consists of one stretch of about 120 kilobase pairs of internal, unique DNA flanked by a variable number of 553-base-pair tandem repeats. The G + C content of the repetitive DNA is extremely high (83%), as ...

The discovery of lymphoid B-Iymphotropic herpesvirus-producing cell lines from M. arctoides peripheral lymphocytes (MAL-l) producing their own lymphotropic virus HVMA was reported earlier [1]. Subsequently, two more M. arctoides virus-producing lymphoid cell lines (MAL-2, MAL-3) were discovered in our laboratory. The cells of some baboon lymphoid cultures, parallel with B-Iymphotropic herpesvir...
