Characterization of Two New Multidrug-Resistant Strains of : Tools for Routine In Vitro Screening of Novel Anti-Mycobacterial Agents.

is a pathogen of global public health concern. This threat is exacerbated by the emergence of multidrug-resistant and extremely-drug-resistant strains of the pathogen. We have obtained two distinct clones of multidrug-resistant after gradual exposure of mc² 155 to increasing concentrations of erythromycin.
