Development and study of nutrient media for determining the biological properties of Listeria.

ABSTRACT

The commercial nutrient media for investigation of the biologic properties of L. monocytogenes is developed. The efficiency of the use of developed media for determination of motility and lecithinase activity of Listeria in the establishment of the isolated culture to the pathogenic species is shown. These nutrient media are developed for visually accurate registration of the motility and lecithinase activity of Listeria when identifying the isolated cultures improving the diagnostics of listeriosis.
