Web17. nov 2024 · Treatment of tuberculosis requires multiple drugs and takes 6-9 months. The lengthy treatment has been mainly attributed to the pre-existing population of bacteria that are tolerant to the antibiotics, but not genetically resistant, known as persisters. Persisters are a small fraction of the bacterial population that survive in the presence of the antibiotic.
