Minimum inhibitory concentration quality-control guidelines for biapenem, DU-6859a, FK-037, levofloxacin, grepafloxacin, and ceftizoxime when using various National Committee for Clinical Laboratory Standards susceptibility test methods. Quality Control Study Group.
Several multilaboratory collaborative studies using broth microdilution and agar dilution (gonococcal tests only) methods of susceptibility testing were performed to establish quality-control (QC) giudelines. Replicate dilution tests with multiple lots of media were performed with National Committee for Clinical Laboratory Standards recommended QC strains (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Enterococcus faecalis ATCC 29212, and Staphylococcus aureus ATCC 29213) by using the following antimicrobials: biapenem, DU-6859a, FK-037, levofloxacin, and grepafloxacin. In addition QC MIC ranges, using appropriate medium modification for Haemophilus influenzae ATCC 49247 and Neisseria gonorrhoeae ATCC 49226 were reported on four (DU-6859a, FK-037, levofloxacin, and grepafloxacin) and two (ceftizoxime and FK-037) antimicrobials, respectively.
