Direct ex vivo IFN-γ ELISPOT for anti-Schistosoma antibodies (+) and anti-Schistosoma antibodies (−) blood units: IFN-γ ELISPOT assay was done as described in the materials and methods section. Eighteen pools were tested corresponding to 180 overlapping core peptides. Plasma from the blood units was tested for viral load and anti-Schistosoma antibodies. Data are presented as the average number of hepatitis C virus (HCV) core-specific direct ex vivo ISC/106 cells in anti-Schistosoma antibodies positive (48) or anti-Schistosoma antibodies negative (57) blood units after subtracting background. The interferon secreting cells (ISCs) values are based on the combined data from all 18 pools of peptides. The box shows the median value and extends from the 25th to the 75th percentile. Whiskers extend down to the smallest value and up to the largest value.
