With the purpose of microorganisms’ molecular genetic species identification, the researches on the material of cultures of pathogenic and conditionally pathogenic species of Mycobacteria and Corynebacteria (reference and pure cultures from sick persons) were carried out. The application of RAPD-PCR analysis has been grounded. Advantages of molecular-genetic methods’ application with the following computer mathematical calculation for PCR pattern comparison and data clasterizing in identification of species of Mycobacteria and Corynebacteria are discussed.
