A New Insight into Phage Combination Therapeutic Approaches Against Drug-Resistant Mixed Bacterial Infections

Area of Science:

• Microbiology
• Infectious Diseases
• Biotechnology

Background:

• Antibiotic resistance poses a significant global health challenge.
• Bacterial pathogens, particularly in conditions like cystic fibrosis (CF), are increasingly resistant to conventional treatments.
• There is an urgent need for novel therapeutic strategies to overcome antimicrobial resistance.

Purpose of the Study:

• To provide an overview of alternative therapies for antibiotic-resistant bacterial infections.
• To examine the mechanisms of action of various alternative approaches.
• To explore the potential of combining phage therapy with other modalities.

Main Methods:

• Literature review of alternative therapies including phage therapy, antimicrobial peptides (AMPs), nanotechnology, monoclonal antibodies (mAbs), microbial therapies, CRISPR, and aptamers.
• Analysis of the synergistic effects of combining phage therapy with these alternative approaches.
• Evaluation of existing research on phage-antibiotic combinations and other phage-based combinations.

Main Results:

• Several alternative therapies show promise in combating antibiotic-resistant pathogens.
• Combinations of phage therapy with other approaches, particularly antibiotics, have demonstrated significant effectiveness.
• While phage-antibiotic combinations are well-studied, other phage-based combinations require further investigation.

Conclusions:

• Alternative therapies offer viable options for treating antibiotic-resistant infections.
• Combination strategies, especially involving phages, are crucial for enhancing treatment efficacy.
• Further research is essential to fully realize the potential of diverse phage combination therapies beyond the established phage-antibiotic approach.
