Recombinant Mycobacterium bovis BCG expressing the chimeric protein of antigen 85B and ESAT-6 enhances the Th1 cell-mediated response.

The chimeric protein that relies on the T-cell epitopes of antigen 85B (Ag85B) and the 6-kDa early secreted antigen target (ESAT-6) has been demonstrated to augment the Th1 immune response. In this study, we developed a recombinant Mycobacterium bovis BCG (rBCG) strain that secretes the chimeric protein of Ag85B and ESAT-6 (rBCG-A(N)-E-A(C)). Immunization with this rBCG strain induced stronger ...

Human T Cell and Antibody-Mediated Responses to the Mycobacterium tuberculosis Recombinant 85A, 85B, and ESAT-6 Antigens

Tuberculosis remains a major health problem throughout the world causing large number of deaths. Effective disease control and eradication programs require the identification of major antigens recognized by the protective responses against M. tuberculosis. In this study, we have investigated humoral and cellular immune responses to M. tuberculosis-specific Ag85A, Ag85B, and ESAT-6 antigens in B...

Recombinant Mycobacterium bovis BCG expressing the Sm14 antigen of Schistosoma mansoni protects mice from cercarial challenge.

The Sm14 antigen of Schistosoma mansoni was cloned and expressed in Mycobacterium bovis BCG as a fusion with the Mycobacterium fortuitum beta-lactamase protein under the control of its promoter, pBlaF*; the protein was localized in the bacterial cell wall. The rBCG-Sm14 strain was shown to be relatively stable in cultured murine and bovine monocytes in terms of infectivity, bacterial persistenc...

Genetic control of antibody responses induced by recombinant Mycobacterium bovis BCG expressing a foreign antigen.

Recombinant Mycobacterium bovis BCG expressing foreign antigens represents a promising candidate for the development of future vaccines and was shown in several experimental models to induce protective immunity against bacterial or parasitic infections. Innate resistance to BCG infection is under genetic control and could modify the immune responses induced against an antigen delivered by such ...

Expression of recombinant Mycobacterium bovis antigen 85B by Mycobacterium smegmatis mc2

Background Bovine tuberculosis (TB) is a disease which constitutes an important economic and zoonotic problem in Latin America. The etiological agent, Mycobacterium bovis, has several antigens described and well characterized. The M. bovis antigen 85B (Ag85B), encoded by fbpB gene, is the bacillus immunodominant antigen and promising target for vaccine and diagnosis development [1]. Ag85B combi...
