This has resulted in the identification of promising recombinant protein antigens (e.g., antigen 85 Complex A,B,C; LprG, AhpC, SodD, AhpD, MAP2698c, MAP3184, MAP3567, MAP0261c, MAP1518) that have the capacity of inducing protective immune responses and overcoming the interference in tuberculosis diagnosis tests using whole-cell based vaccines [50]. The gene discussed is BAG4; the disease is tuberculosis.
