Modern Approaches to the Methods of Creating of Phage Basis for Treatment-Prophylactic a Drug of Bacteriophages Pseudomonas aeruginosa

Abstract

Therapeutic and prophylactic preparations of bacteriophages are considered as an effective modern means of antimicrobial therapy of Pseudomonas aeruginosa infection. Bacteriophages that are part of the drugs must be certified for confirmation of their lytic and genetic properties, which ensures the safety and effectiveness of the use of drugs. In our study, biological and morphological properties were studied for drug design, the spectrum of antibacterial activity of bacteriophages isolated in various regions of Russia was determined. The most important stage of the work was research on ensuring genetic safety of bacteriophage preparations. As a result, a composition of 6 strains of lytic bacteriophages of P. aeruginosa (PaUfa №№ 1, 2, 3, 4, 6, 7) composed of the morphology of the virions to the families Podoviridae and Myoviridae, the order of Caudovirales, phylogenetic genetic groups phiKMV- likevirus , N4-likevirus, PB1-likevirus. The composition has a wide spectrum of antibacterial activity (90.7%) with respect to 818 collisional, epidemiologically significant hospital and clinical strains of P. aeruginosa bacteria, and also quite versatile for various remote territories of Russia and CIS countries.
