Germ-free mice have been shown to have defects in their immune system and energy uptake due to lacking a healthy microbiome. There is also strong evidence for interactions between the mouse microbiome and its brain development and health.
Do germ-free mice live longer?
Mice Raised in a Germ-Free Environment Exhibit Less Age-Related Inflammation and Longer Average Lifespans – Fight Aging!
How does the gut brain axis work?
The gut-brain axis (GBA) consists of bidirectional communication between the central and the enteric nervous system, linking emotional and cognitive centers of the brain with peripheral intestinal functions. Recent advances in research have described the importance of gut microbiota in influencing these interactions.
Why did we use germ-free mice?
Work on germ-free mice began in the 1940’s to understand how microorganisms contribute to physiology and disease. Germ-free mice are a critical tool to uncover the causal relationship between the microbiome and disease, and to determine the mechanistic basis through which microbes influence the host.
What is another term for germ-free?

Can gut bacteria affect mental health?

Why did the scientists test the impact of bifidobacteria on mouse behavior?
Did putting bifidobacteria into the gut of the germ-free mice improve their behavior? It did in some cases. It improved memory in both male and female mice and restored the normal level of anxious behavior of females.
What does the phrase germ-free mean?

What is a germ-free room called?
