[Method of determining the antilysozyme activity of microorganisms].

The method for the determination of the antilysozyme activity of microorganisms is described. The method consists in the cultivation of the strains under study in a lysozyme-containing medium, and the effect of lysozyme inactivation is determined from the growth of Micrococcus luteu S indicator strain adjacent to active strains. The quantitative evaluation of this property is presented. The study of 1 296 strains belonging to 9 genera has disclosed that antilysozyme activity occurs most frequently among Gram-negative bacteria.
