Represents the proportions of the phylum, class and genus of bacteria commonly found in the health gut [8]. Bacteroidetes comprise the majority phylum of the gut microbiome, of which the majority genus is Bacteroides. Firmicutes consists of predominant genera such as Faecalibacterium, Roseburia, and Oscillibacter. The Proteobacteria phylum is proportionally less abundant and mainly represented by the Parasutterella genus. Actinobacteria, such as Propionibacterium and Bifidobacterium, are found in small numbers in the healthy gut.
