In the detection of parasitic infection, the traditional methods based on microscopy often have low sensitivity and/or specificity compared with the newer, molecular tests. An assay based on real-time PCR and a reagent strip test for detecting circulating cathodic antigen (CCA) have both now been compared with urine filtration and microscopy, in the(More)
BACKGROUND The prevalence of peanut allergy has increased in developed countries, but little is known about developing countries with high peanut consumption and widespread parasitic infections. OBJECTIVE We sought to investigate peanut allergy in Ghana. METHODS In a cross-sectional survey among Ghanaian schoolchildren (n = 1604), data were collected on(More)
Recent studies using an internal transcribed spacer (ITS)-based real-time polymerase chain reaction (PCR) for the detection of Schistosoma DNA in urine samples has shown high sensitivity and specificity when performed on controls and known microscopy-positive samples. In this study, using 730 urine samples collected from children in five primary schools(More)
BACKGROUND The classic technique used to detect hookworm infections in population-based surveys is microscopic examination of Kato thick smears of multiple faecal samples per person as variation in soil-transmitted helminth egg output is common. METHODS As an alternative to this time-consuming and logistically difficult procedure, a PCR-based method to(More)
