Figure 1From: Immunogenicity of recombinant Mycobacterium bovis bacille Calmette–Guèrin clones expressing T and B cell epitopes of Mycobacterium tuberculosis antigensProfile of antigen-specific IgG subclasses response against ESAT-6, CFP-10, MTP40 (P1) and MTP40 (P2) B cell epitopes in Balb/c mice (n = 5 for each group) immunized with BCG (open bars) rBCG018 (hatched bars), and rBCG032 (solid bars). The results are expressed as mean OD at 405 nm. * p < 0.05; ** p < 0.01Back to article page
