Fecal samples and rectal swabs adequately reflect the human colonic luminal microbiota.
The appropriateness of the fecal microbiota to adequately reflect the gut microbiota composition from more difficult to access luminal content at different colonic locations has been debated. Here, in a healthy population, luminal samples were collected from terminal ileum to rectum using an unique sampling technique without the need of prior bowel cleansing/preparation. Rectal swabs were collected immediately prior colonoscopy by an experienced physician, and fecal samples were collected at home by the participants themselves. Microbiota composition was evaluated as relative abundance, α-diversity and Bray-Curtis dissimilarities. Our data suggest that fecal samples and rectal swabs present noninvasive, easily accessible, low-cost sampling tools that are accurate proxies to characterize luminal large intestinal microbiota composition.
期刊介绍:
The intestinal microbiota plays a crucial role in human physiology, influencing various aspects of health and disease such as nutrition, obesity, brain function, allergic responses, immunity, inflammatory bowel disease, irritable bowel syndrome, cancer development, cardiac disease, liver disease, and more.
Gut Microbes serves as a platform for showcasing and discussing state-of-the-art research related to the microorganisms present in the intestine. The journal emphasizes mechanistic and cause-and-effect studies. Additionally, it has a counterpart, Gut Microbes Reports, which places a greater focus on emerging topics and comparative and incremental studies.
