Abstract
Bactericidal activity of pyrazinamide (PZA) was tested at pH 5.6 in 7H12 broth against drug-susceptible M. tuberculosis strains. The highest tested concentrations of PZA, 500 and 1,000 micrograms/ml, killed no more than 76% of the bacterial population. These concentrations are more than 32 times greater than the minimal inhibitory concentration (MIC) and the achievable in vivo concentrations. Despite high clinical efficacy of PZA and its so-called sterilizing activity in mouse experiments, this drug is much less bactericidal in vitro than any other known antituberculosis drug.Entities:
