The Laboratory of Molecular Biology performs molecular and biological studies of the bacteriophages that are included in the Eliava Institute’s therapeutic and prophylactic preparations. The researchers of the laboratory have been involved in various scientific studies for the isolation and detailed characterization of bacteriophages against both aerobic and anaerobic bacteria. One of the main interests and activities of the team is investigation the mechanisms of phage – host bacterial cell interaction, study phage genes responsible for the lysis, and identification phage-specific “killer” proteins. The Laboratory has substantial experience and the capability for improvement and standardization of technological schemes for the production of bacteriophages. Laboratory staff developed an exceptionally successful Staphylococcal bacteriophage production technology.
