title: [Dynamic interaction of virulent Pseudomonas aeruginosa bacteriophages with the host bacteria].
abstract: The population interactions of Pseudomonas aeruginosa virulent bacteriophages phi kF77 and phi mnF82 with host bacterial cells were studied in dynamics under the conditions of continuous cultivation in the chemostat regime with glucose limitation. Two different types of maintaining the bacterium and its specific bacteriophages in the population were detected. When P. aeruginosa was cultivated with phage phi mnF82, such a maintenance was realized due to the successive appearance of bacterial mutants resistant to the phage and of phage mutants overcoming this resistance. When P. aeruginosa was cultivated with phage phi kF77, these were maintained owing to the ability of P. aeruginosa to form unstable phage-resistant variants with the segregation of phage-sensitive cells.
