[Influence of low frequency magnetic field on characteristic of Pseudomonas aeruginosa].

AIM: To assess the level of bacteriostatic effect of low frequency magnetic field (LFMF) on Gram-negative bacteria able to form biofilms (Pseudomonas aeruginosa) compared to able to aggregation oligotrophes Caulobactor crescentus, Arcicella aquatica and Verrucomicrobium spinosum. MATERIALS AND METHODS: Frequencies 0.001-100 Hz with magnetic induction value 450 mcT1 together with various variants of time, duration and conditions of cultivation of bacteria were used. Bacteriostatic effectwas assessed by optic methods. RESULTS: Decrease of bacterial growth activity with efficacy coefficient Keef = 0.79 +/- 0.03 was demonstrated. CONCLUSION: LFMF moderately decreases growth of tested bacterial species.
