Mycobacterium habana was isolated in Cuba in 1971. Later, was demonstrated its protection capacity in mycobacterial infection. Here we determined the level of virulence, immunogenicity and the efficacy of three different M. habana strains as attenuated live vaccines. Intratracheal infection of BALB/c mice with high dose M. habana TMC 5135 or IPK-337 strains(More)
Antibodies have demonstrated having a protective effect in animal models of tuberculosis (TB). These experiments have considered the specificity of antigen recognition and the different isotypes and subclasses as significant contributors of this effect. However, the carbohydrate chain heterogeneity on the Fc region of IgG (Fc-IgG) can play an important role(More)
The genus Mycobacterium comprises more than 150 species, including important pathogens for humans which cause major public health problems. The vast majority of efforts to understand the genus have been addressed in studies with Mycobacterium tuberculosis. The biological differentiation between M. tuberculosis and nontuberculous mycobacteria (NTM) is(More)
Circulating monocytes (Mo) play an essential role in the host immune response to chronic infections. We previously demonstrated that CD16(pos) Mo were expanded in TB (tuberculosis) patients, correlated with disease severity and were refractory to dendritic cell differentiation. In the present study, we investigated whether human Mo subsets (CD16(neg) and(More)
AIM Explore the temporal expression of metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) during experimental tuberculosis induced by virulent Mycobacterium tuberculosis strain H37Rv. METHODS BALB/c mice were infected via endotracheal instillation with H37Rv. Groups of mice were euthanized at different time points during(More)
