Background:

  • Streptococcus pyogenes is a significant human pathogen causing various infections.
  • Intracellular bacteria pose treatment challenges due to limited drug accessibility.
  • Bacteriophages are viruses that infect bacteria and can be engineered for therapeutic purposes.

Purpose of the Study:

  • To investigate the potential of a bacteriophage-derived enzyme as a therapeutic agent.
  • To determine if the enzyme can effectively target and eliminate intracellular Streptococcus pyogenes.
  • To explore a novel strategy for treating intracellular bacterial infections.

Main Methods:

  • Production of a specific bacteriophage enzyme.
  • Introduction of the enzyme into human cells.
