Background:

• Bacteriophage therapy offers a novel approach to combatting multidrug-resistant (MDR) bacterial infections.
• Clinical successes highlight phage therapy's potential, but challenges remain regarding in vivo efficacy.
• The human body's microenvironment can impede phage activity and survival.

Purpose of the Study:

• To provide a comprehensive review of phage therapy, focusing on engineered phages.
• To explore applications of engineered phages in antibacterial therapy, tumor therapy, and vaccine development.
• To discuss current challenges and future directions for advancing phage therapy.

Main Methods:

• Review of recent literature on phage therapy and phage engineering.
• Analysis of strategies to enhance phage targeting, stability, and survivability in vivo.
• Examination of synergistic combinations with other therapeutic approaches.

Main Results:

• Engineered phages demonstrate enhanced capabilities for antibacterial and tumor therapies.
• Phage engineering addresses challenges related to in vivo efficacy and stability.
• Phage therapy is being explored for novel applications, including vaccine development.

Conclusions:

• Phage therapy, particularly with engineered phages, holds significant potential for treating MDR infections.
