[Comparison of the protein spectra of typical and atypical mycobacteria using the disc electrophoresis method in polyacrylamide gel].

Protein spectra of 19 strains of typical and atypical mycobacteria were studied. The advantage of protein extracts obtained from the living cells destroyed by press was shown in experiments of fractionation in polyacrylamide gel. On the basis of similarity indices of the protein spectra a conditioned scheme reflecting the extent of similarity of the cultures under study was drawn. there were revealed protein fractions common for the majority of the cultures studied; It was impossible to isolate the fractions strictly specific of individual groups.
