Sensitivity ofNocardiato trimethoprim and sulphonamidesin vitro

Abstract
Studies in vitro of the sensitivity to trimethoprim and sulphonamides of nine strains of N. asteroides, two strains of N. caviae, and one of N. blackwellii are presented. No unequivocal evidence of synergism was found. Despite this, the inclusion of trimethoprim in the drug regime when sulphonamides are used in the treatment of nocardiosis is suggested on empirical grounds.
