gnotobiology

Gnotobiology is the scientific study of living organisms whose surrounding microbial communities are fully known or controlled. It involves working with germ-free or specifically colonized animals and environments to understand how microbes influence health, disease, and biological processes. By precisely managing the microorganisms present, researchers can identify the roles of specific bacteria, viruses, or fungi, leading to insights into immune function, nutrition, and disease mechanisms. This field helps us understand the complex relationships between hosts and their microbiomes, ultimately informing medical, environmental, and biotechnological advancements.
