Bifidobacterium lactis JCM 10602 T (T = type strain) and Bifidobacterium animalis JCM 1190 T were found to be phenotypically similar. These strains were subjected to investigation of their genetic relationships. The 16S rRNA sequence of B. animalis JCM 1190 T was aligned with that of other Bifidobacterium species. B. animalis and B. lactis were the most closely related species in the phylogenetic tree and showed a high similarity in sequences (98.8%). The levels of DNA‐DNA hybridization between the type strains of B. lactis and B. animalis ranged from 85.5 to 92.3%, showing that they represent a single species. It is proposed that B. lactis should be considered as a junior subjective synonym of B. animalis .
