Capillary electrophoresis study of outer membrane proteins of Pseudomonas strains upon antibiotic treatment.

Nosocomial wound infections by Pseudomonas aeruginosa strains have increasing importance in orthopaedic surgery. Outer membrane protein composition and cell-surface hydrophobicity of the bacteria have strong influence on adhesion to living tissues or artificial medical devices. Outer membrane proteins of five Pseudomonas strains (KT 2, KT 7, KT 25, KT 28, KT 39) isolated from orthopaedic patients' wounds and one standard strain NIH Hungary 170000 isolated from pus were examined.
