FAQ

Frequently Asked Questions About Germ-Free Mice

What are germ-free (GF) mice?

Germ-free (GF) mice are laboratory animals with no detectable living microorganisms or parasites, internally or externally, based on currently available detection methods. Maintaining GF mice requires rigorous microbial control, specialized environments, and dedicated equipment.

What are the characteristic differences between germ-free (GF) and specific pathogen-free (SPF) mice?

In comparison to conventional SPF mice, GF mice exhibit notable physiological and morphological changes, such as an enlarged cecum, thinned intestinal musculature, reduced liver and heart size, weakened innate immune response, and high susceptibility to microbial infections.

Why use germ-free (GF) mice in scientific research?

Germ-free mice help researchers investigate causal relationships between the microbiome and disease and study how microorganisms influence host physiology. Because these mice lack detectable microorganisms, researchers can use them as a controlled baseline or introduce specific microbial communities to test targeted hypotheses.
