Summary
This study introduces a transgenomic approach to link gut microbiome variations with metabolic phenotypes. It identifies key gut bacteria, like Faecalibacterium prausnitzii, that significantly influence host metabolism and health.
Area of Science:
- Microbiome research
- Metabolomics
- Host-microbe interactions
Background:
- Human gut microbiome variations influence health, disease, and drug responses.
- The molecular basis of microbe-host interactions and the roles of specific bacteria remain unclear.
Purpose of the Study:
- To develop a "transgenomic" approach linking gut microbiome and metabolic phenotype (metabotype) variation.
- To identify key functional members of the microbiome influencing host metabolism and health.
Main Methods:
- Analysis of fecal and urinary samples using spectroscopic, microbiomic, and multivariate statistical tools.
- Comparison of gut microbiomes between Chinese and American populations.
- Modeling microbial-host metabolic connectivities.
Main Results:
- Identified structural differences in Chinese and American gut microbiomes.
- Introduced the concept of functional metagenomics to characterize influential microbiome members.
- Faecalibacterium prausnitzii variations were linked to modulation of eight urinary metabolites, highlighting its functional importance.
Conclusions:
- The transgenomic approach provides a foundation for functional metagenomics.
- This approach can probe systemic effects of drugs and diet relevant to public health.
- Understanding host-microbiome symbiosis is crucial for personalized and public healthcare.

01:18Functions of the Gut Microbiota
The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...
01:18Dysbiosis of the Gut Microbiota
The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:22Introduction to the Human Microbiota
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity, and disease...
01:22Gut-Brain Axis
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...
01:27Microbiota of the Large Intestine
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
