Abstract

Mutagenic activity of N-methyl-N'-nitro-N-nitrosoguanidine with respect to Brucella melitensis was studied. In the course of this study the method of obtaining auxotrophic brucella mutants was elaborated. Numerous assortiment of auxotrophic mutants of different types was obtained. In a number of cases the acquisition of auxotrophy was accompanied by profound changes of the strain, such as the changes in morphology of colonies, in the biochemical activity, in the capacity of agglutination and in the virulence.
