Preclinical efforts to discover and develop new drugs and vaccines for tuberculosis are hampered by the reliance on colony-forming unit (CFU) counts as primary outcomes for in vivo efficacy studies and the slow growth of Mycobacterium tuberculosis. The utility of bioluminescent M. tuberculosis reporter strains for real-time in vitro and ex vivo assessment of drug and vaccine activity has been d...

Smith, D. W. (University of Wisconsin, Madison), G. B. Fregnan, L. DeLaquerriere-Richardson, and E. Valdivia. Induction of acquired resistance in guinea pigs with defatted Mycobacterium tuberculosis vaccines. J. Bacteriol. 88:87-92. 1964.-Residues of mycobacteria exhaustively extracted with neutral organic solvents have been shown to produce a level of resistance against tuberculosis in guinea ...

Owing to the devastation caused by tuberculosis along with the unsatisfactory performance of the Bacillus Calmette-Guérin (BCG) vaccine, a more efficient vaccine than BCG is required for the global control of tuberculosis. A number of studies have demonstrated an essential role of biotin biosynthesis in the growth and survival of several microorganisms, including mycobacteria, through deletion ...

Mycobacterium tuberculosis 6-kDa early secretory antigenic target (ESAT-6) is a dominant target antigen for cell-mediated immunity in the early phase of tuberculosis. The fms-like tyrosine kinase 3 ligand (FL) that induces potent immune response has been used as an adjuvant in vaccine development. In this study, a new recombinant plasmid (pIRES-epitope-peptides-FL) encoding three T cell epitope...

Next-generation vaccines for tuberculosis should be designed to prevent the infection and to achieve sterile eradication of Mycobacterium tuberculosis. Mucosal vaccination is a needle-free vaccine strategy that provides protective immunity against pathogenic bacteria and viruses in both mucosal and systemic compartments, being a promising alternative to current tuberculosis vaccines. Micro and ...

Objectives Tuberculosis (TB) has still remained a global health issue. One third of the world's population is infected with tuberculosis and the current BCG vaccine has low efficiency; hence, it is necessary to develop a new vaccine against TB. The aim of the current study was to evaluate the efficiency of a novel DNA vaccine encoding Mtb32C-HBHA antigen in inducing specific immune responses ag...

background: although the efficacy of bacillus calmette-guerin (bcg) vaccine in the prevention of tuberculosis has been noted consistently, the use of bcg vaccine is not without risk. in this study we aimed to evaluate immunologically, children with complication of bcg vaccination in north of iran.materials and methods: this case-control study began in 30 jan 2013 and was completed in 2 jul 2015...

Objective(s) Tuberculosis (TB) is the leading cause of mortality among the infectious diseases, especially in developing countries. One of the main goals in tuberculosis research is to identify antigens which have the ability of inducing cellular and/or humoral immunity in order to use them in diagnostic reagents or vaccine design. The aim of this study was to clone and express the TB'0.4 prot...

Objective(s): Production of effective tuberculosis (TB) vaccine is necessity. However, the development of new subunit vaccines is faced with concerns about their weak immunogenicity. To overcome such problems, polymers-based vaccine delivery systems have been proposed to be used via various routes. The purpose of this study was to determine the potential of polymeric particles as future vaccine...

Objective(s): Infection with tuberculosis (TB) is regarded as a major health issue. Due to the emergence of antibiotic resistance during TB treatment, prevention via vaccination is one of the most effective ways of controlling the infection. DNA vaccines are developed at a greater pace due to their ability in generating a long-lasting immune response, higher safety com...
