Laboratory of General Microbiology

The main research interest and scientific activity of the laboratory is the isolation of bacteriophages against various pathogenic bacterial strains and study phage-biology and genetics, as well as the elaboration of different medicinal forms of phage preparations and development of technology for phage production. The laboratory personnel participate in various international scientific projects in the field of medicine, veterinary and microbial ecology. In addition to scientific-research directions, the laboratory is creating new therapeutic forms of phage preparations, developing and standardizing the technology of their production. The laboratory actively cooperates with the commercial structures of the Eliava-Consortium (“Bacteriophage Biopreparations”, “Pharmacy”, “Phage therapy Center”) both in terms of expanding the antimicrobial spectrum (activity) of existing commercial phage preparations, as well as preparing individual phages for patients.
