[The multiplication dynamics of pathogenic bacteria in relation to the trophic and temperature cultivation conditions].

The comparative study of the dynamics of multiplication of Listeria monocytogenes and Yersinia pseudotuberculosis in organic and synthetic media and in distilled water at temperatures of 37 degrees C and 6 degrees C was carried out. This study revealed that in organic media the multiplication of bacteria was good at 37 degrees C and 6 degrees C. In mineral media and distilled water their multiplication was observed only at 6 degrees C. Moreover, conditions necessary for the multiplication of pathogenic bacteria in distilled water were shown; these conditions depended on the inoculated dose, the number of autolyzed microbial cells and the state of the culture. Proofs of the multiplication of the bacteria under the conditions of minimum nutrition and low temperature were obtained with the use of labeled 3H-thymidine.
