The Microbiome and Immunity

The Microbiome and Immunity

The human microbiome is the collection of all the microbes (bacteria, bacteriophage, fungi, protozoa, and viruses) that live on and in the human body. Changes in the human microbiome are known to be associated with human disease, so understanding the nature and consequences of these changes is of great interest to researchers and health professionals.[1]

In 2007, the National Institutes of Health Common Fund started the Human Microbiome Project. This 10-year project was designed to increase our understanding of the human body’s complex and abundant microbial communities and their role in health and disease.[2]

In a healthy gut microbiome, resident microorganisms help protect against the invasion of opportunistic pathogens. They do this through a process called colonization resistance. This involves different methods to inhibit pathogens, such as:[3]

  • producing anti-microbial compounds
  • outcompeting pathogens for space in the gut
  • maintaining the mucus layer so pathogens cannot reach intestinal cells
  • training the immune system to respond to pathogens

Keeping your gut healthy to support a healthy immune system may include taking a probiotic supplement. A healthy gut microbiome has a high diversity of microbes, so look for a formula with multiple strains.
