FIG. 2.

Different patterns of recognition of GroES peptides. Stack columns represent the frequency of negative and weakly and strongly positive PBMC proliferation in 17 HS group controls (C) and 25 untreated patients with active TB (T). Response patterns: A, p1-16; B,p9-24; C, p17-32 and p25-40; D, p41-56, p49-64, p65-80, and p73-88; E, p33-48, p57-72, and p81-100 (means for the individual peptides in categories C, D, and E). For each sequence, two peptides containing residues from M. tuberculosis and M. leprae were tested and the higher response from each pair was recorded.
