Abstract

Abstract: The aim of the present study was to determine the effect of the rotating magnetic field (RMF) on the growth, cell metabolic activity and biofilm formation by S. aureus, E. coli, A. baumannii, P. aeruginosa, S. marcescens, S. mutans, C. sakazakii, K. oxytoca and S. xylosus . Bacteria were exposed to the RMF (RMF magnetic induction B = 25–34 mT, RMF frequency f = 5–50 Hz, time of exposure t = 60 min, temperature of incubation 37 °C). The persistence of the effect of exposure ( B = 34 mT, f = 50 Hz, t = 60 min) on bacteria after further incubation ( t = 300 min) was also studied. The work showed that exposure to RMF stimulated the investigated parameters of S. aureus, E. coli, S. marcescens, S. mutans, C. sakazakii, K. oxytoca and S. xylosus, however inhibited cell metabolic activity and biofilm formation by A. baumannii and P. aeruginosa . The results obtained in this study proved, that the RMF, depending on its magnetic induction and frequency can modulate functional parameters of different species of bacteria.
