摘要
Thirty-three clinical isolates of Corynebacterium jeikeium were examined for susceptibility to 27 antimicrobial drugs with the agar dilution test. Sheep-blood-supplemented Mueller-Hinton agar performed better than Wilkins-Chalgren agar. Disk susceptibility (Bauer-Kirby) tests were carried out in parallel with 24 of the chemotherapeutic agents. All isolates were susceptible to teicoplanin and vancomycin. All isolates resisted fosfomycin, mupirocin, and trimethoprim-sulfamethoxazole. The isolates varied in susceptibility to ciprofloxacin, doxycycline, fusidic acid, ofloxacin, and tetracycline; most were susceptible to rifampin. Surprisingly few discrepancies between agar dilution and disk diffusion tests were encountered when utilizing NCCLS interpretive criteria currently valid for enterococcal isolates.
