[Sensitivity of nosocomial microflora circulating in a transplantation clinic to medicinal bacteriophages]

Area of Science:

• Microbiology
• Infectious Diseases
• Bacteriophage Research

Background:

• Postoperative infectious complications pose a significant clinical challenge.
• Bacteriophage therapy offers a potential alternative or adjunct to antibiotics.
• Understanding bacterial susceptibility to phages is crucial for therapeutic application.

Purpose of the Study:

• To determine the sensitivity of bacterial isolates from postoperative infections to phagolysis.
• To identify key bacterial species exhibiting high sensitivity to bacteriophages.
• To investigate variations in phage sensitivity based on phage origin.

Main Methods:

• Collected 239 bacterial isolates from patients with postoperative infectious complications.
• Assessed the sensitivity of these isolates to various bacteriophages (phagolysis).
• Compared sensitivity across different bacterial species and phage sources.

Main Results:

• Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli demonstrated the highest sensitivity to bacteriophages.
• Significant variations in isolate sensitivity were observed even for phages from the same producer.
• Identified differences in sensitivity profiles depending on the bacteriophage source.

Conclusions:

• Bacteriophage therapy holds promise for treating specific postoperative infections caused by S. aureus, P. aeruginosa, and E. coli.
• Phage sensitivity testing is essential due to variability in efficacy.
• Bacterial sensitivity to phages can serve as a marker for biological strain properties.
