DNA‐DNA hybridization is a reliable method for determining the phylogenetic relationship between bacterial strains. The hybridization kinetics for DNA from different slowly‐growing mycobacteria were measured optically in a spectrophotometer. The results indicate that M. tuberculosis and M. bovis belong to one species. M. avium and M. intracellulare are two species, but some serotypes, now designated M. intracellulare , actually belong to M. avium.
