title: [Approaches to classifying bifidobacteria based on DNA structural data].
abstract: A brief historical review of classifications of Bifidobacteria demonstrates the difficulties in this problem, for the present-day classifications are far from being satisfactory. Based on the genotypical heterogeneity of the genus Bifidobacterium, the authors validate the possibility of raising it to the status of the family Bidobacteriaceae fam. nov. The principle of forming new genera within the frames of this hypothetical family, discussed in the paper, originates from the genomic similarity of representatives of some species of this group of microorganisms.
