Abstract
The relationship between Bifidobacterium lactis and Bifidobacterium animalis was examined by comparative analysis of tuf and recA gene sequences and by restriction fragment length polymorphism analysis of their internal 16S-23S transcribed spacer region sequences. The bifidobacterial strains investigated could be divided into two distinct groups within a single species based on the tuf, recA, and 16S-23S spacer region sequence analysis. Therefore, all strains of B. lactis and B. animalis could be unified as the species B. animalis and divided into two subspecies, Bifidobacterium animalis subsp. lactis and Bifidobacterium animalis subsp. animalis.
