Interestingly, Mi contains lesser number of virulent genes as compared to Mtb and Mb. In addition, it has antigenic proteins similar to Mtb. Further, 16 vaccine candidate peptides have been predicted from CD11_6 (Mi), making it a suitable vaccine candidate against Mtb. Live Mi is known to induce abscess, hence we have used heat killed Mi. In addition, HK Mi induced significantly better generation of both memory CD4 T cells and CD8 T cells [Figs. 6 and 7], which is a fundamental attribute of a successful vaccine. The gene discussed is CD4; the disease is abscess.
