Factors influencing susceptibility of Nocardia species to trimethoprim-sulfamethoxazole

J. E. Bennett, A. E. Jennings

Research output: Contribution to journalArticlepeer-review


Demonstration of synergism between trimethoprim and sulfamethoxazole against 10 Nocardia isolates was found to be critically dependent upon the isolate, the duration of incubation and the trimethoprim-sulfamethoxazole ratio. Inoculum effect was not significant. The trimethoprim-sulfamethoxazole ratio in the commercial, fixed-dose combination was found to contain too little trimethoprim to be optimal for Nocardia.
