Effects of 50 Hz magnetic fields on the viability of different bacterial strains. med./bio.

Published in: Electromagn Biol Med 2005; 24 (3): 293-300

Aim of study (acc. to author)

To study the effect of a 50 Hz magnetic field on the growth of different bacterial strains.

Background/further details

Bacteria with different cell shapes were compared: rod-shaped bacteria (Escherichia coli, Leclercia adecarboxylata) and spherical bacteria (Staphylococcus aureus, Paracoccus denitrificans, Sphingomona paucimobilis, Rhodococcus erythropolis).
The temperature during exposure was maintained in the range of 24-26°C.

Main outcome of study (acc. to author)

A decrease of optical densities in exposed samples was found. The magnetic field effect was bigger for rod-like bacteria. The authors conclude that magnetic field effects depend on the shape of exposed cells.
