Emerging drug-resistant strains are posing significant challenges to the global fight against tuberculosis (TB) and it is a critical task to detect treatment failure as early as possible. Researchers from the Marius Nasta Institute (MNI) and the Research Center Borstel, Leibniz Lung Center (FZB) have now evaluated a new test for the early detection of changes in the bacterial load of Mycobacterium tuberculosis, which provides an indication of treatment success within hours. The results of the study have now been published in the Journal of Infection.
