The levels of IgA against Ag85B were also significantly higher in the minimal TB group (p < 0.001) and the advanced TB group (p < 0.001) than in the NI group and were significantly higher in the advanced TB group than in the LTBI group (p = 0.008), but there was no significant difference between the LTBI and minimal TB groups (Figure 3D). Here, CD79A is linked to tuberculosis.
