[Isolation and analysis of Pseudomonas aeruginosa PAO mutants resistant to nonlysogenic bacteriophages].
Nonlysogenizing Pseudomonas aeruginosa PAO bacteriophages were studied. According to morphology of the plaques, they were distributed into three groups: phi k, phi m and phi mn. The mutants of P. aeruginosa PAO resistant to these bacteriophages were selected. On the basis of cris-cross resistance analysis of the mutants, a formal scheme of the receptor sites on the P. aeruginosa PAO bacterial cell surface is drawn. It is shown that bacteriophages phi k and phi m use different receptors for their adsorption. The receptors of phi m and phi mn phages are specifically interconnected. Thus, the receptor for phi k phages is connected with the receptor for phage phi 11. It appears that the receptor for bacteriophage E79 is identical to those of phi m phages. The phi m receptor is of a composite structure: it includes two different receptors used by phi mn phages.
