title: Quality control limits for disk diffusion and broth microdilution susceptibility tests with Haemophilus test medium.
abstract: A six-center collaborative study was performed with the aim of developing quality control test limits for both disk diffusion and broth microdilution susceptibility tests with Haemophilus influenzae ATCC 49247 using Haemophilus test medium. Quality control ranges are presented for 18 antimicrobials: ampicillin, amoxicillin-clavulanate, ampicillin-sulbactam, cefuroxime, cefamandole, cefonicid, cefotaxime, ceftriaxone, ceftizoxime, ceftazidime, cefixime, chloramphenicol, tetracycline, trimethoprim-sulfamethoxazole, rifampin, imipenem, aztreonam, and ciprofloxacin.
