The goal of this observational study is to learn about how the blood leucocytes from patients with and without exposure or disease from tuberculosis (TB) are able to kill live mycobacteria (M. tuberculosis). The main question it aims to answer is: Is intracellular growth suppression of M. tuberculosis in peripheral blood mononuclear cells variable among healthy blood donors and higher than in patients with latent TB compared to active TB?
