title: Simple fibroblast-based assay to test the pyrazinamide susceptibility of Mycobacterium tuberculosis.
abstract: A simple fibroblast-based assay (SFA) was found to be efficient in evaluating the susceptibilities of clinical isolates of Mycobacterium tuberculosis to pyrazinamide (PZA). Forty-five clinical isolates were examined. The MICs of PZA for susceptible strains in an SFA were between 3.13 and 12.5 microg/ml, and the MICs of PZA for resistant strains were more than 100 microg/ml.
