Abstract: The present invention is about a mycobacterium smegmatis vaccine, a split product of mycobacterium smegmatis. This vaccine has made good use of the adjuvant function of bacterial cellwall and antigenic specificity of tropina which can stimulate the production of cytokine and consists of many immunologically competent CpG fragments of bacteria DNA. Such vaccine is prepared by treating newly-cultured thalli with a physical quassation technique. This vaccine is capable of enhancing normal immune function against TB, promoting the recovery of normal immune function in TB patients with hypofunction, and depressing the immunological responses in TB patients with hyperfunction. It is especially effective in the prevention and treatment of MTB carriers.
