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


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.


CONCLUSIONS
LFMF moderately decreases growth of tested bacterial species.
