Effect of shear stress on growth, adhesion and biofilm formation of Pseudomonas aeruginosa with antibiotic-induced morphological changes
چکیده انگلیسی

The aim of this study was to investigate the effect of shear stress and antibiotic-induced morphological changes on the growth, adhesion and biofilm formation ability of Pseudomonas aeruginosa. A modified microtitre plate assay was used to quantify adhesion, biofilm formation and planktonic culture density of P. aeruginosa ATCC 27853 under the effect of 0.5× minimal inhibitory concentrations (MICs) of piperacillin/tazobactam, imipenem and meropenem. Hydrodynamic conditions were achieved by orbital shaking at 250 rpm with the presence of a glass bead in each microtitre well. These conditions decreased adhesion and biofilm formation abilities, increased planktonic culture density over 1 h and decreased planktonic culture density over 16 h for bacteria with antibiotic-induced morphological changes in comparison with static conditions. Our results demonstrate the importance of using a high-throughput dynamic model to assess the adhesion and biofilm formation behaviour of P. aeruginosa with antibiotic-induced morphological changes and suggest the possible use of sub-MIC antibiotics in clinical applications to prevent infections acquired by haematogenous spread. This dynamic model provides a better simulation of in vivo conditions of adhesion and biofilm formation of P. aeruginosa with altered morphologies induced by β-lactam antibiotics.
