Hamster embryo fibroblast cells can be transformed after infection by ultraviolet light-irradiated herpes simplex viruses type 1 (HSV-1) or type 2 (HSV-2). Two ofl2 strains of HSV-1 and 7 of 15 strains of HSV-2 induced cell transformation. Transformed cells from two strains of HSV-2 and one strain of HSV-1 have been tested for oncogenicity in newborn Syrian hamsters. One cell line transformed b...

BACKGROUND Herpes simplex virus type 2 (HSV-2), one the most common causes of genital ulcers, appears to increase both the risk of HIV acquisition and HIV transmission. HSV-2/HIV co-infection among pregnant women may increase the risk of perinatal transmission of HIV. This study describes rates of HSV-2 among pregnant women in Haiti and HSV-2 test performance in this population. METHODS Unlin...

A 131,000 molecular weight herpes simplex virus type 1 (HSV-1) glycoprotein designated antigen number 6 (Ag-6) was previously shown to possess almost exclusively HSV-1-specific antigenic sites. Fused rocket and crossed immunoelectrophoresis of fractions obtained from hydroxylapatite chromatography of crude HSV-1 antigen (Triton X-100-solubilized, infected tissue culture cells) showed that a sub...

Infection with herpes simplex virus type 1 (HSV-1) and HSV-2 is initiated by viral glycoprotein D (gD) binding to a receptor on the host cell. Two receptors, herpesvirus entry mediator (HVEM) and nectin-1, mediate entry in murine models of HSV-1 and HSV-2. HVEM is dispensable for HSV-2 infection of the vagina and brain, but is required for WT pathogenesis of HSV-1 infection of the cornea. By ch...

During lytic herpes simplex virus (HSV) infections, the HSV virion host shutoff protein (UL41) accelerates the turnover of host and viral mRNAs. Although the UL41 polypeptides from HSV type 1 (HSV-1) strain KOS and HSV-2 strain 333 are 87% identical, HSV-2 strains generally shut off the host more rapidly and completely than HSV-1 strains. In a previous study, we identified three regions of the ...

BACKGROUND/OBJECTIVES Herpes simplex virus type 2 (HSV-2) is a common infection among HIV infected people. HSV type specific serologies permit the diagnosis of previously unrecognised HSV-2 infection. While substantial psychosocial morbidity has been associated with a clinical diagnosis of genital herpes, the burden associated with a serological diagnosis of HSV-2 is unclear. This study prospec...

The cytotoxicity and the antivirus activity of Pd(II) and Pt(II) complexes with pyridine-2-carbaldehyde thiosemicarbazone (HFoTsc) against HSV replication were evaluated on four HSV strains-two wt strains Victoria (HSV-1) and BJA (HSV-2) and two ACV(R) mutants with different tk gene mutations R-100 (TK(A), HSV-1) and PU (TK(N), HSV-2). The experiments were performed on continuous MDBK cells and...

Many studies have chronicled the "epidemiologic synergy" between human immunodeficiency virus (HIV) and herpes simplex virus type 2 (HSV-2). HIV adversely affects the natural history of HSV-2 and results in more frequent and severe HSV-2 reactivation. Few longitudinal studies, however, have examined whether HSV-2 is associated with increased HIV plasma viral loads or decreased CD4 counts. The a...
