Specific anti-DisA antibodies in DisA immunized mice, TB patients, and Mtb-infected mice. (A) Sera were collected from purified protein DisA immunized BALB/c mice in our previous study and sera from PBS immunized mice as control, antibody titers against DisA were assayed by ELISA as shown dilution. (B) Antibody titers against DisA in TB patients (n = 53) and healthy control (n = 113) were assayed by ELISA (1:200). (C) Antibody titers against DisA in Mtb-infected mice. Sera were collected from BALB/c mice monthly at 1–6 month (m) post-infection, and specific anti-DisA antibody titers were detected by ELISA (1:200).
