Control the Activity of Erwinia Amylovora Bacterium by Magnetic Field

Abstract

We study the effect of promoting low magnetic field exposure on antimicrobial activity against Erwinia amylovora (E. Amylovora) bacterium. For this purpose, we treated E. amylovora at 28°C with two intensities (0.2T and 0.5T) of the magnetic field for one hour to see the intensity of bacterial growth inhibition. Bacterial growth was measured in experimental samples. The results indicate that exposure to E. amylovora to 0.2T and 0.5T for 1 hour reduced bacterial growth. Dielectric relaxation studies of treated and untreated alive bacterium showed changes of the surface charge distribution of the bacterium which indicates changes in the receptor properties and hence cell communications. The study showed bacteria treated with the magnetic field which was exposed for an hour, adjusted its cellular activity, slowing the rate of growth and affecting microbial pathogenicity. The effect was higher at 0.5 T than 0.2 T. We concluded that magnetic field formation is a promising technique for treating this type of bacteria.
