Laboratory of Bacteriophages


Research profile:

Bacteriophage Laboratory is engaged in phage isolation for therapeutic purposes, as well as biological, morphological and genetic characteristics of procured phages. Our research includes the development of new bacteriophage preparations, focusing on the optimization of phage amplification conditions, purification, and assessment phage stability under various storage conditions. We also study the immune response to bacteriophages, including the determination of serum antiphage antibody levels in patients undergoing phage therapy, and investigate possible interactions between phages and immune cells and their consequences. Our team selects phages for therapeutic purposes based on bacterial susceptibility and monitors the effects of phage therapy, including the potential development of phage resistance. Additionally, we conduct preclinical studies of bacteriophage preparations, examining tissue penetration, pharmacokinetics, effectiveness in animal models, and toxicity. Other research topics include experimental phage therapy in animals and the use of phages for food safety and environmental protection.

Current research:

  • Studies on Enterococcus phages isolated from patients with urinary tract infections involving its anti-biofilm action.
  • Optimalization of isolation and amplification of Acinetobacter baumannii The development of methodology allowing for their extended stability in phage preparations.
  • Studies on phage ability to induce defensin production by epithelial cells (especially hBD-2).

Head

Head: Prof. dr hab. n. med. Andrzej Górski, specialty: internal medicine; subspecialty: clinical immunology. (0000-0002-0863-6041)

Prof. Andrzej Górski has been associated with the Institute initially as a member of its scientific council, then as it chair in 1999. After his first term as rector of the Medical Academy in Warsaw he decided to apply for directorship of the Institute. As a head of Bacteriophage Laboratory he leads the team engaged in research on bacteriophages. The results have been published in reputed journals opening new perspectives for the therapeutic applications of phages not only as anti-bacterials but also as immunomodulators. His initiative led to the establishment in 2005 of Phage Therapy Center treating patients with antibiotics-resistant infections with experimental phage therapy. Prof. A. Górski is also editor in chief of AITE, an Institute’s journal that became one of the leading scientific journal in Poland. Prof. A. Górski has also been active in the field of ethics in science that led to his election as chair, Commission for Ethics in Science (since 2019).

Most important scientific achievements
  • Demonstration that bacteriophages exhibit immunomodulatory activities, while different phages may mediate different effects – which could possibly be used  in the treatment of autoimmune diseases and in transplantation (Górski A. et al. Therapeutic phages as modulators of the immune response: practical implications.
