The results of investigations of the effect of magnetic fields on the growth of bacteria have so far been inconclusive. Leusden1 found that the growth of coliform organisms and staphylococci was not affected by exposure to magnetic fields. Jennison2 grew 25 species of bacteria, yeasts, and molds on solid media between the poles of an electromagnet which provided a homogeneous field of 3000 Oe. After 48 hr of exposure, he checked the cultures for size of colony, staining reactions, pigment production, and spore formation. He found no difference between magnet cultures and controls. However, Magrou and Manigault3 showed that tumor production by Bacterium tumefaciens on a strain of Pelargonium zonale was retarded by magnetic fields.
