Influence of temperature on the variability of Listeria monocytogenes in the course of its prolonged existence in soil-packed colomns with flowing water

Research Institute of Epidemiology and Microbiology of the Siberian Branch of the Rus. Acad. of Med. Sci., Vladivostok, Russia

The capacity of L.monocytogenes for prolonged existence in the soil at different temperatures (18-20°C and 6-8°C) has been shown. The viability of these bacteria in the soil depends both on their properties and the temperature factor. Low temperatures (6-8°C) ensure, on the whole, the stable preservation of the biological properties of the bacteria. More pronounced variability of L.monocytogenes at a temperature of 18-20°C is an adaptive propertiy, ensuring high ecological plasticity of the bacteria and their prolonged existence in the soil.
