Henrissat B. Are stool samples suitable for studying the link between gut microbiota and obesity?.

The study of the gut microbiota has become a priority in the scientific world. Thus, the vast majority of studies are based on analysis of the digestive microbiota by testing faeces, analysed by metagenomic studies, with sequences analysed by complex computer programs []. Most of these studies are not conducted by people who are familiar with microbiology, so that most studies merely describe the percentage of reads found in the four large clades observed in humans: Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria.
