Abstract

Biologically low temperature was studied for its effect on the survival of populations and their biochemical and molecular-genetical state. The research was carried out on Yersinia pseudotuberculosis and Shigella sonnei models. It is established that the process of low-temperature adaptation of the populations may occur either at the level of the whole population with participation of inducible cold isoenzymes or at the level of a part of population, the temperature being a selection factor of the adapted cells.
