title: [Bifidobacterial species composition of digestive tract of people of different age groups].
abstract: The quantitative and species composition of bifidoflora of intestinal content of people of different age groups has been studied. It was established that B. longum subsp. infantis, B. bifidum, B. brev, B. longum subsp. longum and B. dentium were the dominant species of intestinal bifidoflora of people of all ages. The dependence of the species composition of intestinal bifidobacteria on the human age was shown. A decrease of species diversity of bifidobacteria in elderly people was observed.
