A longitudinal cohort study of sexually active women 18-30 years of age was conducted to identify variables associated with the acquisition of herpes simplex virus type 2 (HSV-2) infections. Six hundred seventy HSV-2-seronegative women were followed up at 4-month intervals for 1 year; acquisition of HSV-2 antibodies was detected in 32 of these women. Black(More)
BACKGROUND The etiology of bacterial vaginosis (BV) is poorly understood, but better definition of the risk factors associated with its acquisition should improve our understanding of this complex disease entity. METHODS A longitudinal cohort study of young sexually active women was conducted to identify variables associated with BV acquisition. Seven(More)
Gardnerella vaginalis is associated with a spectrum of clinical conditions, suggesting high degrees of genetic heterogeneity among stains. Seventeen G. vaginalis isolates were subjected to a battery of comparative genomic analyses to determine their level of relatedness. For each measure, the degree of difference among the G. vaginalis strains was the(More)
Acute pelvic inflammatory disease (PID) is a major public health problem. An estimated 1 million cases occur annually in the United States. PID is a major cause of infertility and ectopic pregnancy. Prevention of the significant medical and economic sequelae of acute PID relies on the institution of appropriate treatment regimens that are based on the true(More)
BACKGROUND Genital infections due to herpes simplex virus type 2 (HSV-2) are characterized by frequent reactivation and shedding of the virus and by the attendant risk of transmission to sexual partners. We investigated the effects of vaginal coinfections and hormonal contraceptive use on genital tract shedding of HSV-2 in women. METHODS A total of 330(More)
HSV-specific CD8(+) T cells provide constant immunosurveillance of HSV-1 latently infected neurons in sensory ganglia, and their functional properties are influenced by the presence of latent virus. In this study, we show that ganglionic HSV-specific CD8(+) T cells exhibit a higher functional avidity (ability to respond to low epitope density) than their(More)
Epidemiological studies indicate that the exogenous sex steroid medroxyprogesterone acetate (MPA) can impair cell-mediated immunity, but mechanisms responsible for this observation are not well defined. In this study, MPA administered to mice 1 wk prior to HSV type 1 (HSV-1) infection of their corneal mucosa impaired initial expansion of viral-specific(More)
BACKGROUND Herpes simplex virus type 2 (HSV-2), the primary cause of genital herpes, is one of the most prevalent sexually transmitted diseases worldwide. Epidemiologic serosurveys suggest that infections occur more frequently in women than in men. GOAL The goal of the study was to identify unique correlates of HSV-2 infection in women that might(More)
BACKGROUND Bacterial vaginosis (BV) is a perturbation of vaginal flora characterized by reduced levels of lactobacilli and concomitant overgrowth of anaerobic bacterial species. BV is highly prevalent and associated with multiple adverse outcomes, including enhanced human immunodeficiency virus transmission. Because recent reports reveal that herpes simplex(More)
In C57BL/6 (B6) mice, most herpes simplex virus (HSV)-specific CD8 T cells recognize a strongly immunodominant epitope on glycoprotein B (gB498) and can inhibit HSV type 1 (HSV-1) reactivation from latency in trigeminal ganglia (TG). However, half of the CD8 T cells retained in latently infected TG of B6 mice are not gB498 specific and have been largely(More)
