Figure 1. Bifidobacterium-based gut microbiome partitions. (A) Model fit according to BIC; (B) distribution of subjects across the 7 partitions. Partition #7 consists of subjects for whom no Bifidobacterium was detected (no-Bif); (C) scaled contribution of each Bifidobacterium species to each partition. Higher DMM model contributions are associated with a higher relative abundance of a particular species. Species are ordered according to hierarchical clustering based on Euclidean distance. Gray indicates alpha parameters below 10^-5. More abundant species: B. longum to B. dentium and sub-dominant species: B. moukalabense to B. pseudolongum.
