Gut Prevotella as a possible biomarker of diet and its eubiotic versus dysbiotic roles-A comprehensive literature review.

Gut Prevotella as a possible biomarker of diet and its eubiotic versus dysbiotic roles-A comprehensive literature review. Br J Nutr. 2019 Mar 29;:1-24 Authors: Precup G, Vodnar DC Abstract Gut microbiota has a profound impact on human health. Emerging data shows that dietary patterns are associated with different communities of bacterial species within the gut. Prevotella species have been correlated with plant rich diets, abundant in carbohydrates and fibres. Dysbiosis within the gut ecosystem has been associated with the development of non-communicable diseases such as obesity, metabolic syndrome, inflammatory bowel disease, irritable bowel syndrome, colorectal cancer, type 1 diabetes, allergies and other diseases. The purpose of this comprehensive literature review was to evaluate the available data on the impact of diet on Prevotella genus, as a dietary fibre fermenter in the gut, as well as its implications as a potential biomarker for homeostasis or disease state, through its metabolite signature. Studies were identified by conducting PubMed, Web of Science Core Collection and Google Scholar electronic searches. We found 85 publications reporting the impact of dietary patterns on gut microbial communities including Prevotella or Prevotella/Bacteroides ratio in particular. Moreover, the role of Prevotella species on health status was also evaluated. Prevotella possess a high genetic diversity, representing one of the important g...
