چکیده انگلیسی
Dormant, slow-growing, antibiotic-tolerant Mycobacterium tuberculosis undermine the shortening of tuberculosis treatment to less than 6 months and are thought to be characterised by intracellular lipid bodies. Antibiotic effects on such persisting bacilli escape evaluation as they cannot be readily cultured. We identified cells containing lipid bodies in sputum smears from 86 newly diagnosed pulmonary tuberculosis patients and monitored these cells daily in 42 patients over the first 14 days of treatment with rifampicin, the experimental compound SQ-109, or both agents combined. Counts of Nile-Red-positive lipid-body containing cells were correlated with those of Auramine-O-positive cells and colony forming units of viable Mycobacterium tuberculosis on agar plates. Rifampicin but not SQ-109 significantly reduced colony forming units but all treatments distinctively and significantly changed the proportions of lipid body-containing bacilli and viable Mycobacterium tuberculosis. Monitoring lipid-body containing bacilli in sputum during treatment with experimental antituberculosis regimens may identify putative treatment-shortening regimens.
