title: Magnetic susceptibility of microorganisms.
abstract: Total magnetic susceptibility of 13 species and varieties of bacteria was investigated using the relative method of Guy. It has been established that the index of magnetic susceptibility is a constant characteristic of bacteria. Total magnetic susceptibility ranged from --0.3295.10(-6) in Escherichia P678 to --0.4965.10(-6) in Proteus. It has also been established that magnetic susceptibility changes during long-term passages of bacteria in fluctuating +/- 0.1 Oe) magnetic field. This is suggestive of a low threshold of their magnetic susceptibility and permits a rough assessment of the importance of fluctuations of the geomagnetic field for the viability of microbes.
