Scrub and murine typhus infections are under-diagnosed causes of febrile illness across the tropics, and it is not known how common they are in Bangladesh. We conducted a prospective seroepidemiologic survey across six major teaching hospitals in Bangladesh by using an IgM enzyme-linked immunosorbent assay. Results indicated recent exposure (287 of 1,209, 23.7% seropositive for Orientia tsutsug...

We tested for negative effects of West Nile virus (WNV) on a breeding population of eastern bluebirds in Alabama by comparing fecundity and reproductive success in years before and after the arrival of WNV and by comparing fecundity, reproductive success, and overwinter survival of seropositive and seronegative individuals within the same population in the same years. We found that female blueb...

OBJECTIVE To assess the effect of bacterial vaginosis (BV) on the risk of high-grade squamous intraepithelial lesions (HSIL) among HIV-seropositive women. METHODS A hospital-based prospective cohort study of HIV-seropositive women was conducted in Johannesburg, South Africa from January 2005 to September 2009. Multivariate log-binomial and Poisson regressions were used to estimate prevalence ...

Neuropsychological impairments punctuate the early neurological involvement among HIV-1 infected patients. Three groups of patients, twenty in each were selected. The first group consisted of seronegative local controls, the second being a group of asymptomatic seropositive patients and the third a group of seropositive symptomatic individuals. All these three groups were tested using standard ...

This study was planned to determine HIV seroprevalence among pulmonary tuberculosis patients, to characterize the isolated mycobacteria into typical and atypical strains and to evaluate the drug resistant pattern of mycobacterial isolates. The study aims to correlate multidrug resistance (MDR) and HIV seropositivity status in pulmonary tuberculosis patients. During the year 1994-1997, 750 pulmo...

  Background and Objectives:  Helicobacter pylori cause a chronic gastric infection, and may cause extra gastrointestinal disease. The association between H. pylori infection and serum lipid profiles is still controversial. The aim of this study was to investigate any possible relationship between H. pylori infection and lipid levels. Materials and Methods: The subj...

This study was conducted to measure cell-mediated immune response in healthy Epstein Barr virus (EBV)-seropositive individuals using a tissue culture "growth inhibition" assay (regression assay) where peripheral blood lymphocytes (PBLs) were tested for their ability to inhibit the outgrowth of the autologous lymphoblastoid cell lines (LCLs). Inhibition of the outgrowth of the autologous LCLs wa...

BACKGROUND This analysis compared the frequency of persistent Trichomonas vaginalis (TV) among HIV-seropositive and HIV-seronegative women. METHODS Data were obtained from women enrolled in an open cohort study of sex workers in Kenya. Participants were examined monthly, and those diagnosed as having TV by saline microscopy were treated with single-dose 2 g oral metronidazole. All women on an...

Toxoplasma gondii (T. gondi) is divided three main clonal lineages designated as type I, II, and III and atypical genotypes were also detected. The distribution of T. gondii genotypes varied from one geographic area to another. This study characterized of T. gondii isolates from pregnant women in Jazan. Genetic analysis of the GRA6-coding fragment was performed for T. gondif genotyping using PC...
