OBJECTIVE The objective of this study was to assess the risk factors for and persistence of Mycoplasma genitalium (MG) in a highly exposed female population in Kenya. STUDY DESIGN Two hundred fifty-eight sex workers in Nairobi, Kenya, 18 to 35 years of age, were enrolled. Every 2 months, cervical samples were collected for MG, Chlamydia trachomatis (CT),(More)
Epidemiological, animal, and in vitro investigations suggest that Chlamydia trachomatis infection engenders acquired immunity, the basis for which is incompletely defined, especially in humans. In a prospective cohort study of women at high risk for C. trachomatis infection, we found that, at baseline and after adjustment for age and other potential(More)
BACKGROUND Serologic studies indicate that human herpesvirus 6 (HHV-6) infects 90 percent of children by two years of age. Little is known about the acquisition, virologic course, and clinical manifestations of HHV-6 infection. METHODS We prospectively studied a cohort of 277 children from birth through the first two years of life to define the pattern of(More)
OBJECTIVES To simultaneously examine associations of bacterial vaginosis (BV) with potential risk factors in both the female and her male partner. STUDY DESIGN We recruited women 18-45 years of age and their male partners from clinics in Nairobi, Kenya. All underwent face-to-face standardized interview physical examination, human immunodeficiency virus(More)
OBJECTIVE The aim of our study was to examine vaginal tissue during 3 phases of the menstrual cycle for the number of cell layers and epithelial immune cells. STUDY DESIGN Vaginal biopsies were performed during 3 phases of the normal menstrual cycle (menstrual, days 1-5; preovulatory, days 7-12; and postovulatory, days 19-24) in 74 subjects. A subset of(More)
OBJECTIVE To identify the effects of depomedroxyprogesterone acetate (DMPA) on vaginal microbial flora and epithelium. METHODS Women who desired DMPA for contraception were evaluated before and at 3 and 6 months after initiation of 150-mg DMPA injections every 3 months. At each visit, we assessed genital symptoms, vaginal signs, vaginal microflora, and(More)
The genetic homogeneity of nine commensal and infecting populations of Candida albicans has been assessed by fingerprinting multiple isolates from each population by Southern blot hybridization first with the Ca3 probe and then with the 0.98-kb C1 fragment of the Ca3 probe. The isolates from each population were highly related, demonstrating the clonal(More)
The objective of this study was to examine genital tissue, vaginal fluid, and vaginal microbial flora at 3 phases of the menstrual cycle in asymptomatic women. Vaginal examinations were performed 3 times in 74 women: at the menstrual phase (days 1-5), the preovulatory phase (days 7-12), and the postovulatory phase (days 19-24). Flora of 50 women without(More)
Cytolytic T cells play a major role in controlling herpes simplex virus type 2 (HSV-2) infections in humans. In an effort to more thoroughly evaluate the response to HSV-2 directly, ex vivo, we developed an enzyme-linked immunospot (ELISPOT) assay that utilized pools of overlapping synthetic peptides presented by autologous dendritic cells to purified(More)
BACKGROUND Previous studies using viral cultures rarely reported herpes simplex virus type 2 (HSV-2) isolation from the mouth. We sought to characterize oral HSV-2 shedding as detected by HSV DNA polymerase chain reaction among HSV-2-seropositive men. METHODS Participants collected daily swabs from oral and anogenital areas for HSV detection with a(More)
