In vitro susceptibility of Mycobacterium fortuitum and M. chelonei to sisomicin, gentamicin and tobramycin.

Abstract

The in vitro action of sisomicin, gentamicin and tobramycin against 62 strains of Mycobacterium fortuitum and 20 strains of M. chelonei was investigated. At a drug concentration of 4 micrograms/ml, 31, 31 and 11%, respectively, of M. fortuitum strains and 90, 25 and 15%, respectively, of M. chelonei strains, were inhibited.
