[Possible connection between the virulence of Pseudomonas aeruginosa bacteria and their ultrastructural characteristics].

The results of the electron-microscopic study of P. aeruginosa isolated from patients with surgical inflammatory purulent processes and from the environment (water, soil) are presented. The morphological features of the subcellular structure of virulent and non-virulent P. aeruginosa strains, as well as their adaptation properties, appearing under unfavorable conditions have been established.
