 In accordance, genome analysis of "Prevotella copri" showed it was deficient in the ability to degrade host glycans and is more genetically equipped for plant glycan degradation.In a study of gut bacteria of children in Burkina Faso (in Africa), "Prevotella" made up 53% of the gut bacteria, but were absent in age-matched European children.Studies also indicate that long-term diet is strongly associated with the gut microbiome composition—those who eat plenty of protein and animal fats typical of Western diet have predominantly "Bacteroides" bacteria, while for those who consume more carbohydrates, especially fibre, the "Prevotella" species dominate.
