Clinical Scorecard: How to Test Whether Antibiotics Actually Work

At a Glance

Key Highlights

• Antimicrobial Single-Cell Testing (ASCT) tracks bacterial death rates under antibiotic exposure.
• Drug tolerance is genetically determined and linked to treatment failures.
• Combining MIC results with killing speed improves prediction of patient outcomes.
• Bedaquiline and pretomanid show superior performance under starvation conditions.
• The platform allows simultaneous testing of multiple strains against various antibiotics.

Guideline-Based Recommendations

Diagnosis

• Utilize ASCT for more accurate assessment of antibiotic efficacy.

Management

• Incorporate killing speed measurements alongside MIC for personalized treatment.

Monitoring & Follow-up

• Regularly assess bacterial response to antibiotics using time-kill curves.

Risks

• Relying solely on conventional susceptibility tests may lead to treatment failures.

Patient & Prescribing Data

Patients with difficult-to-treat bacterial infections.

Personalized antibiotic selection based on genetic tolerance and killing speed.

Clinical Best Practices

• Combine MIC testing with ASCT for improved treatment predictions.
• Monitor bacterial strains for genetic markers of drug tolerance.
• Consider starvation conditions when evaluating antibiotic effectiveness.
