Proteomic analysis of drug-susceptible and multidrug-resistant nonreplicating Beijing strains of Mycobacterium tuberculosis cultured in vitro

The existence of latent tuberculosis infection (LTBI) is one of the main obstacles hindering eradication of tuberculosis (TB). To better understand molecular mechanisms and explore biomarkers for the pathogen during LTBI, we cultured strains of Mycobacterium tuberculosis (Mtb) under stress conditions, mimicking those in the host granuloma intracellular environment, to induce entry into the non-replicating persistence stage. The stresses included...
