OBJECTIVES To determine the prevalence of human immunodeficiency virus (HIV), Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG) among immigrant female sex workers (FSW) according to their geographic area of origin and identify possible risk factors independently associated with current infection with CT and/or NG. STUDY DESIGN Cross-sectional(More)
BACKGROUND We recently identified polymorphisms in Kaposi sarcoma-associated herpesvirus (KSHV)-encoded microRNA (miRNA) sequences from clinical subjects. Here, we examine whether any of these may contribute to KS risk in a European AIDS-KS case-control study. METHODS KSHV load in peripheral blood was determined by real-time quantitative polymerase chain(More)
Within the framework of hepatitis C virus (HCV) prevalence monitoring, we evaluated oral fluid (OF), which is richer in IgG than whole saliva, as a possible alternative to serum for the detection of HCV antibodies. Paired OF and serum samples were collected from 90 individuals, including 45 HCV-positives and 45 HCV-negatives. The detection of HCV antibodies(More)
BACKGROUND Rapid identification of the etiological agent in bloodstream infections is of vital importance for the early administration of the most appropriate antibiotic therapy. Molecular methods may offer an advantage to current culture-based microbiological diagnosis. The goal of this study was to evaluate the performance of IRIDICA, a platform based on(More)
Molecular methods for bacterial pathogen identification are gaining increased importance in routine clinical diagnostic laboratories. Achieving reliable results using DNA based technologies is strongly dependent on pre-analytical processes including isolation of target cells and their DNA of high quality and purity. In this study a fast and semi-automated(More)
BACKGROUND Only about 50% of patients chronically infected with HCV genotype 1 (HCV-1) respond to treatment with pegylated interferon-alfa and ribavirin (dual therapy), and protease inhibitors have to be administered together with these drugs increasing costs and side-effects. We aimed to develop a predictive model of treatment response based on a(More)
Human herpesvirus 8 (HHV-8) is the etiologic agent of Kaposi's sarcoma (KS). Several studies indicate horizontal HHV-8 transmission among children in areas where KS is endemic, but few studies have assessed acquisition of HHV-8 by children in low seroprevalence areas. Antibody screening was carried out for HHV-8 and Epstein-Barr virus (EBV) on 787 serum(More)
We report the evaluation of a new real-time PCR assay for hepatitis C virus (HCV) genotyping. The assay design is such that genotype 1 isolates are typed by amplification targeting the nonstructural 5b (NS5b) subgenomic region. Non-genotype 1 isolates are typed by type-specific amplicon detection in the 5' noncoding region (5'NC) (method 1; HCV genotyping(More)
Peroxygenic acid, under the brand name Virkon, has unleashed great debate following contradictory reports of its efficacy and spectrum of activity. The aim of this study was to test the biocidal activity of the compound against 10 different micro-organisms, following standard in-vitro test procedures. Bactericidal, fungicidal and sporicidal activities were(More)
BACKGROUND Current treatment of chronic hepatitis C virus (HCV) infection has limited efficacy -especially among genotype 1 infected patients-, is costly, and involves severe side effects. Thus, predicting non-response is of major interest for both patient wellbeing and health care expense. At present, treatment cannot be individualized on the basis of any(More)
