The human microbiota is the ecological community of commensal, the aggregate of symbiotic and pathogenic microorganisms that resides on or within any of several human tissues and biofluids. Human microbiota can be considered as a new ＇organ＇ due to its important role in maintaining good health. The interaction mechanisms between microbe and host are comprehensive and complex.
