The microbiome and aging

Abstract

The microbiota changes as the host ages, but also the relationship between host and bacteria impacts host aging and life expectancy. Differences in the composition of certain bacterial species in the human gut and skin microbiome have been identified between the elderly and the young. In this sense, it has been suggested that the manipulation of the microbiota of older adults would be an innovative strategy in the prevention and treatment of age-related comorbidities.
