Fig. 1From: Unusual sub-genus associations of faecal Prevotella and Bacteroides with specific dietary patternsDifferences in oligotype composition between omnivores and non-omnivores. Dendrogram of Prevotella (a) and Bacteroides (b) oligotype representative sequences and their average relative abundance in omnivores (inner circle) and non-omnivores (outer circle). Asterisks denote oligotypes significantly different in abundance between the two groups (*P < 0.05; **P < 0.01). Yellow circles denote oligotypes showing 100 % match with sequences in the NCBI nr databaseBack to article page
