Wayne, Pennsylvania, Clinical and Laboratory Standards Institute has published M24--Susceptibility Testing of Mycobacteria, Nocardia spp., and Other Aerobic Actinomycetes, 3rd Edition and M62--Performance Standards for Susceptibility Testing of Mycobacteria, Nocardia spp., and Other Aerobic Actinomycetes, 1st Edition.
M24 includes susceptibility testing procedures for Mycobacterium tuberculosis complex (MTBC), clinically significant slowly and rapidly growing mycobacterial species, Nocardia spp., and other aerobic actinomycetes. Also included in this standard are recommendations for selecting agents for first-line and second-line drug testing, organism group-specific methodologies, reporting recommendations, and organism quality control criteria. Recommendation regarding agent selection for testing mycobacteria are based primarily on published guidelines.
Clinical and Laboratory Standards Institute document M62—Performance Standards for Susceptibility Testing of Mycobacteria, Nocardia spp., and Other Aerobic Actinomycetes includes the minimal inhibitory concentrations and quality control ranges developed following the standards described in CLSI document M24.1 The data in the tables are valid only when the methodology in CLSI document M241 is followed.
