In vitro studies of Chlamydia trachomatis susceptibility and resistance to rifampin and rifabutin

Abstract

Although rapid emergence of antibiotic-resistant mutants of Chlamydia trachomatis occurs when the organism is grown in subinhibitory concentrations of rifampin, no such mutants could be demonstrated when the organism was propagated under the same conditions in subinhibitory levels of the related drug rifabutin.
