Clinical bacteriology in low-resource settings: today's solutions

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Global Health

Background:

• Low-resource settings face significant burdens from infectious diseases and antimicrobial resistance (AMR).
• Effective AMR control relies on quality clinical bacteriology, yet implementation faces infrastructural, technical, and behavioral challenges in these areas.

Purpose of the Study:

• To explore successful implementation of clinical bacteriology in low-resource settings.
• To describe a framework for implementing clinical bacteriology in general referral hospitals in low- and middle-income countries.

Main Methods:

• Focus on adapting and implementing conventional, culture-based techniques, as most current diagnostics are not designed for low-resource environments.
• Prioritize harmonized, quality-assured, and tropicalized equipment, consumables, and techniques.
• Rationalize bacterial identification and antimicrobial resistance testing.

Main Results:

• Successful implementation requires integrating diagnostics into clinical care and patient management.
• Clinically relevant specimens must be appropriately selected and prioritized.
• Development of open-access training materials and information management tools is essential.

Conclusions:

• On-site validation and field adoption of diagnostics in low-resource settings are critical for timely implementation.
• Implementing clinical bacteriology improves patient management and surveillance for local antibiotic guidelines and national policies.
• This implementation supports AMR containment and the prevention/control of hospital-acquired infections.
