Abstract

The in vitro activities of TP-271, a novel fluorocycline antimicrobial, against 22 isolates of Mycobacterium abscessus, 22 isolates of Mycobacterium fortuitum, and 19 isolates of Nocardia spp. were studied by a microtiter broth dilution method. The MIC(90)s for M. abscessus, M. fortuitum, and Nocardia spp. were 0.5 μg/ml, 0.03 μg/ml, and 8 μg/ml, respectively. TP-271 was significantly more active than the respective control drug in virtually all tests.
