FIG. 5.

Rv1169c is recognized only by sera from patients with extrapulmonary infections. The children reporting extrapulmonary infections belonging to group 3 mounted significant IgG responses to Rv0978c (P < 0.001), Rv1169c (P = 0.0344), and the 19-kDa antigen (P = 0.0084) but not to the Rv1818c antigen (P > 0.5). Among the clinical categories studied, Rv1169c elicited immunoreactivity only with group 3 children. The data represented here are comprised of IgG antibody reactivities in sera of patients. HC, healthy controls.
