[Initial stages of interaction of temperate phage 04 with Pseudomonas aeruginosa cells]

The first steps of the interaction of the temperate pilus-dependent phage 04 with susceptible and 04-lysogenic cells of Pseudomonas aeruginosa were investigated. The 04-lysogenic cells retained their ability to adsorb viral particles on the pili. However, after the translocation to the cell surface, the bacteriophage failed to infect the immune microorganism. It is assumed that was modified the surface of 04-immune cells due to lysogenic conversion, and this modification presented the terminal tail fibers of viral particles interacting from with the outer membrane of P. aeruginosa cells.
