Evaluation of in vitro susceptibility to sparteine in four strains of Mycobacterium tuberculosis.

ABSTRACT: Sparteine is an alkaloid with bacteriostatic activity on the genus Mycobacterium. The aim of this study was to evaluate the antimicrobial activity of sparteine on the growth of 4 ATCC strains of Mycobacterium tuberculosis (susceptible, resistant to isoniazid, resistant to rifampicin and multidrug-resistant) in vitro. Validation of bactericidal activity of sparteine sulfate was carried out through an adaptation of the Microscopic-Observation Drug-Susceptibility (MODS) method according to the guidelines of the Peruvian National Health Institute. The results demonstrate that at concentrations of 25; 50 and 100 Mm of sparteine sulfate, there is no development of colony-forming units in any of the 4 evaluated strains. Our results demonstrate the potential in vitro antimicrobial effect of sparte
