Detection of Mycobacterium tuberculosis complex DNA in PBMCs of asymptomatic adults by QuantiFERON status

Detection of M tuberculosis complex DNA by QuantiFERON status in all participants (A), HIV-uninfected participants (B), and HIV-infected participants (C). (D) IS6110 copy number per 20 μL well in CD34-negative and CD34-positive PBMCs. (E) rpoB copy number per 20 μL well in CD34-negative and CD34-positive PBMCs. p values for contingency tables were calculated with Fisher's exact tests. p values for comparison of continuous variables were calculated with Mann-Whitney tests. In panels D and E, proportions with undetectable M tuberculosis complex DNA are displayed below the scatter plots for each condition, and lines show median values. LOD=limit of detection. PBMC=peripheral blood mononuclear cell.
