title: [The relationship of the indices of solar-geomagnetic activity and the autofluctuations in the biological properties of Staphylococcus aureus 209 subcultures in vitro].
abstract: The in vitro study of effect of such factors as solar activity and the magnetic field of the Earth revealed their influence on the autofluctuations of the biological activity of S.aureus 209 subcultures. Differences in the activity of the synthesis of DNAase, RNAase and delatinase could increase two-- to tenfold during the year. Relationships between heliogeophysical characteristics and the biological activity of bacteria could be both direct and reverse. The study also revealed that at the periods of increased solar and geomagnetic activity S.aureus may spontaneously dissociate in the soil, forming subcultures with greater biological activity than the initial strains.
