Clinical and Infection-Control Considerations

• Therapy selection: For severe infections (e.g., bacteremia, hospital-acquired pneumonia), prefer agents with proven clinical efficacy against ESBL producers; outpatient or uncomplicated UTIs may allow non-carbapenem options guided by susceptibility and clinical judgement.
• Antimicrobial stewardship: M45 supports stewardship by improving accuracy of AST results and interpretive comments to prevent inappropriate use of broad-spectrum agents while ensuring effective therapy.
• Surveillance and outbreak detection: Accurate ESBL detection informs infection control measures and epidemiologic tracking.

• Capnophilic (CO2): 5% CO2 for H. influenzae, N. meningitidis, and HACEK.
• Anaerobic: Anaerobic chamber or gas-generating sachet for Bacteroides (48 hours minimum).
• Microaerophilic: Campy gas mixture for Campylobacter (48 hours).
