Objective To combine the Bacillus Calmette Guerin(BCG)strain and Mycobacterium tuberculosis H37 Ra strain(H37Ra)as parent strains by protoplast fusion to yield a fusion strain(B/R strain)in order to investigate the virulence and safety of a new type of tuberculosis vaccine in mice. Methods Two hundred and four C57BL/6mice were randomly divided into 4groups:36mice receiving saline,56 mice inoculated with the B/R strain,56 mice inoculated with the H37 Ra strain,and 56 mice inoculated with the BCG strain.Mice ...
