    "abstract": "The effects of the exposure of the bacterium, Leptospira interrogans serovar\ncanicola to a constant magnetic field with magnetic flux density from a\npermanent ferrite magnet = 140 mT were studied. Changes in Leptospira cells\nafter their exposure to the field were determined on the basis of changes in\ntheir growth behavior and agglutination immunoreactivity with a homologous\nantiserum using darkfield microscopy together with visual imaging. The data\nshowed that the exposed Leptospira cells have lower densities and lower\nagglutination immunoreactivity than the unexposed control group. Interestingly,\nsome of the exposed Leptospira cells showed abnormal morphologies such as large\nlengths. We discussed some of the possible reasons for these observations.",
