Bacteriophages of Pseudomonas aeruginosa

Bacteria Pseudomonas aeruginosa, being opportunistic pathogens, are the major cause of nosocomial infections and, in some cases, the primary cause of death. They are virtually untreatable with currently known antibiotics. Phage therapy is considered as one of the possible approaches to the treatment of P. aeruginosa infections. Difficulties in the implementation of phage therapy in medical practice are related, for example, to the insufficient number and diversity of virulent phages that are active against P. aeruginosa. Results of interaction of therapeutic phages with bacteria in different conditions and environments are studied insufficiently. A little is known about possible interactions of therapeutic phages with resident prophages and plasmids in clinical strains in the foci of infections. This chapter highlights the different approaches to solving these problems and possible ways to expand the diversity of therapeutic P. aeruginosa phages and organizational arrangements (as banks of phages) to ensure long-term use of phages in the treatment of P. aeruginosa infections.
