[Influence of sub-mics of selected antibiotics on hydrophobic and adhering properties of Klebsiella pneumoniae strains isolated from urine samples].

The aim of this study was to evaluate the effects of sub-MICs of selected antinbiotics on hydrophobic and adhering properties of Klebsiella pneumoniae rods. Cefotaxime, gentamicin, ciprofloxacin and tetracycyline were used. The hydrophobicity was evaluated according to the method of Rosenberg et al. The adhering properties were estimated by method of Christensen et al. The exposure of K. pneumoniae strains to subMICs of antibiotics reduced hydrophobicity and adhesion to polystyrene. All antibiotics used at 1/2 MICs significantly reduced the hydrophobicity and adhesion to polystyrene of K. pneumoniae strains.
