Comparative in vitro antimicrobial activity of a new carbapenem, doripenem: tentative disc diffusion criteria and quality control

Abstract

Assuming the MIC susceptible breakpoints for doripenem are < or =1 mg/L for the streptococci and < or =2 mg/L for all other genera, then disc diffusion zone diameter breakpoints can be proposed. In addition, MIC and/or disc diffusion quality control ranges of doripenem were determined for 10 ATCC reference strains.
