[Mode of the rational use of Pseudomonas aeruginosa bacteriophages in therapeutic and epidemic control practice].
Ecological aspects of the circulation of P. aeruginosa and P. aeruginosa bacteriophages under hospital conditions were under study. The statement concerning the formation of triple parasitic systems was put forward. The influence of these systems on the formation of phage and antibiotic resistance in P. aeruginosa hospital strains was studied. Spontaneous circulation of faintly virulent phages taking part in the formation of triple parasitic systems was shown not to ensure the elimination of P. aeruginosa hospital strains in clinics. Construction of highly virulent phages adapted to local P. aeruginosa strains was the only way of ensuring the protection of patients. Theoretical and practical approaches to the use of highly active bacteriophages for controlling P. aeruginosa infection were substantiated. The realization of these approaches resulted in achieving not only a clinical, but also essential epidemic control effect in cases of purulent septic infections caused by P. aeruginosa (a decreased frequentcy of hospital infections from 40.8% to 8.93%).
