Five novel herpesviruses were identified in suid species from Africa (common warthog, Phacochoerus africanus) and South-East Asia (bearded pig, Sus barbatus; babirusa, Babyrousa babyrussa) by detection and analysis of their DNA polymerase genes. Three of the novel species, P. africanus cytomegalovirus 1, P. africanus lymphotropic herpesvirus 1 (PafrLHV-1) and S. barbatus lymphotropic herpesviru...

BACKGROUND There is difficulty in gathering data on the prevalence of human T-cell lymphotropic virus in blood donors as confirmatory testing is not mandatory in Brazil. This suggests there may be an underreporting of the prevalence. OBJECTIVE To estimate the prevalence of human T-cell lymphotropic virus types 1 and 2 in donors of a blood bank in Caruaru, Brazil. METHODS This was an observa...

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...

Simian T-lymphotropic retroviruses with structural, antigenic, and cytopathic features similar to the etiologic agent of human acquired immunodeficiency syndrome, human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV), have been isolated from a variety of primate species including African green monkeys (STLV-IIIAGM). This report describes nucleic acid cross-reactivi...

recurrent spontaneous rupture of the urinary bladder has rarely been reported in english articles. this condition may be difficult to diagnosis before a laparotomy due to acute peritonitis. herein we describe a case of recurrent spontaneous rupture of the bladder in a 39-year-old woman with human t-lymphotropic virus type 1 (htlv-1) -associated myelopathy/topical spastic paraparesis (ham/tsp).

Recent findings have shown that the expression of the seven dered UT-7 cells readily infectable by different T-lymphotropic syncytium-inducing HIV-1 and HIV-2 isolates. Interesttrans-membrane G-protein–coupled CXCR4 (the receptor for the stromal cell-derived factor [SDF]-1 chemokine) is necesingly, HIV-1 infection of CXCR4 expressing UT-7 cells (named UT-7/fus) induces the formation of polynucl...

Some viruses preferentially infect restricted subpopulations of lymphocytes . The pathogenesis of the diseases induced by these lymphotropic viruses is determined at least in part by this selectivity of infection . Herpesvirus saimiri, a lymphotropic herpesvirus that causes no apparent disease in its natural host Saimiri sciureus (squirrel monkey), induces a fulminant lymphoproliferative syndro...
