Radial UPGMA tree based on the copy numbers of MIRU-VNTR 24-loci of 109 isolates of the current study and additional 240 isolates from Tessema et al. Inner circle: lineages and sub-lineages (EAI - East African Indian, LAM - Latin American Mediterranean, CAS - Central Asia). Small rectangle in the second circle: affiliation of the isolate (green - current study, red - Tessema et al. northwest Ethiopia). Small rectangle in the third circle: drug resistance pattern (green - fully susceptible, red - MDR, blue - resistant but not MDR). Small rectangle in the outer circle: clustering according to 24-loci MIRU-VNTR and spoligotyping pattern analysis; isolates with identical genotyping profile are highlighted in same color.

Characterization of CD27 expression on PPD-specific CD4 T cells in whole blood.
<p>(A) The cut off for CD27 expression was determined based on the corresponding isotype control for each antibody. Shown is a representative staining for IFNγ-FITC and CD27-PE as well as their corresponding IgG<sub>1</sub> isotype controls that were used to determine the cut off. (B) Gating strategy to identify PPD-specific CD4 T cells and to analyse the CD27 expression on IFNγ-positive CD4 T cells after 6 h of PPD-stimulation during the cross-sectional study. (C) Representative staining for negative and positive controls using PPD diluent and SEB, respectively, for stimulation.</p
Down regulation of CD27 on PPD-specific CD4 T cells is associated with active Tuberculosis independent of the HIV status and with progression to active TB in a HIV<sup>+</sup> seroconverter.
<p>(A) Ratio of IFNγ<sup>+</sup> CD4 T cells that are CD27<sup>+</sup> divided by those that are CD27<sup>−</sup> is shown for 4 different groups of PPD responders delineated by TB disease state and by HIV serology. CD4<sup>+</sup> T cells were analyzed for each sample using a whole blood intracellular cytokine assay. (B) Histogram analysis of CD27 expression on IFNγ<sup>+</sup> PPD-specific CD4 T cells (blue line) and total CD4 T cells (black line, grey) over a 15 months period in two subjects who became HIV infected. Subject H19 (<b>upper panel</b>) was diagnosed and treated for active TB 15 months after HIV infection. Subject H228 (<b>lower panel</b>) did not develop TB within three years after HIV infection. Longitudinal analysis of CD27 expression for one subject was determined simultaneously by flow cytometry.</p
