Key facts

• Cefotaxime [Susceptibility] for meningitis by Disk diffusion (KB)
• Cefotaxime
• Susceptibility of an isolate to cefotaxime in the context of a patient with meningitis, i.e., the "meningitis breakpoint". Various agencies, including the FDA and CLSI in the U.S. and EUCAST in Europe, publish guidelines for determining susceptibility of different organisms to different antimicrobials. In most cases, susceptibility does not vary by type of infection, but for a few specific types of infection, including meningitis, pneumonia and urinary tract infection, certain antimicrobials have different susceptibility thresholds.
