A two-step screening strategy was developed to identify strong immunogenic polypeptides with putative vaccine and/or adjuvant activity. In the first step, a mycobacterial genomic DNA library was screened in vitro to identify plasmids encoding polypeptides that stimulate splenocytes from mycobacteria-immunized mice and T cells from PPD-positive healthy donors to produce interferon-γ. In the second...

It is of great importance to develop an efficient vaccine against M. tuberculosis since the only available vaccine, M. bovis-BCG, has a low efficacy.
