Abstract excerpt

Bifidobacterium longum predominates in the human gut throughout the life span, from birth to old age, and could alter the intestinal microbial population and immune function in the elderly. We investigated the intestinal bacterial diversity in the elderly, and further evaluated the genetic diversity and population structure of B. longum. The results revealed a distinct difference in gut bacterial populations...
