Comment on: effects of sleeve gastrectomy on the composition and diurnal oscillation of gut microbiota related to the metabolic improvements

      The human gastrointestinal tract harbors a diverse and rich ecosystem of microbes, which includes both bacteria and prokaryotic archaea spanning over one hundred trillion in number with approximately 160 species per individual [

      ]. The gut microbiome and human host should have a symbiotic relationship with a thriving home for the microbiome and development of immunity for the human host. However, whole body health requires a delicate balance of the gut microbiome. The human host–gut microbial relationship can exist in significant disharmony in disease states of obesity and metabolic syndrome.
