Differential levels of activation markers depending on the strain of infection. Plasma from adult TB cases was assessed by ELISA for levels of C-reactive protein (a), Neopterin (b) and Beta2-microglobulin (c) before and after initiation of TB therapy. The strain of infection was determined using spoligotyping. Maf = Mycobacterium africanum; Mtb = Mycobacterium tuberculosis sensu stricto. n = 29 for both groups. Bar indicates median. Data were analysed using Wilcoxon ranked sums test within groups and Mann-Whitney U-test between groups
