Progress in Alternative Strategies to Combat Antimicrobial Resistance: Focus on Antibiotics

Area of Science:

• Microbiology
• Infectious Diseases
• Pharmacology

Background:

• Antimicrobial resistance (AMR) is a global health crisis, rendering common infections untreatable.
• No new classes of antibiotics have been developed in two decades, increasing reliance on alternative strategies.
• Rising morbidity and mortality rates underscore the urgent need for novel therapeutic approaches.

Purpose of the Study:

• To review and synthesize emerging strategies for combating multidrug-resistant (MDR) pathogens.
• To explore alternatives to conventional antibiotic therapy.
• To assess the potential of novel approaches in clinical settings.

Main Methods:

• Literature review of current and proposed alternative strategies.
• Categorization of methods including combination therapy, enzyme/protein targeting, and drug delivery systems.
• Inclusion of unconventional techniques like CRISPR-Cas systems.

Main Results:

• Identified diverse strategies including combination therapy, resistance mechanism targeting, advanced drug delivery, physicochemical methods, and CRISPR-Cas.
• Highlighted the potential of these alternatives to address the limitations of traditional antibiotics.
• Emphasized the need for further development and clinical application.

Conclusions:

• Novel strategies show promise in overcoming antimicrobial resistance.
• These alternatives could revolutionize the treatment of multidrug-resistant infections.
• Continued research and development are crucial for clinical implementation.
