Handling and Experimentation with Germ-Free Mice

Area of Science:

• Microbiology
• Gastroenterology
• Animal Models

Background:

• Mammals are colonized by microorganisms post-birth, primarily in the gastrointestinal tract.
• The intestinal microbiota plays a crucial role in host physiology.
• Gnotobiotic animal models are vital for investigating host-microbe interactions.

Purpose of the Study:

• To provide a detailed guide on managing and manipulating the gut microbiota in germ-free (GF) mice.
• To highlight the importance and utility of GF mice in microbiome research.

Main Methods:

• Step-by-step description of GF mouse management.
• Detailed procedures for gut microbiota manipulation in GF mice.

Main Results:

• The chapter outlines practical methodologies for maintaining and experimentally altering the gut microbiota composition in GF mice.
• Establishes GF mice as a valuable tool for microbiome research.

Conclusions:

• Effective management and manipulation of the gut microbiota in GF mice are critical for advancing microbiome research.
• GF mice offer a unique platform for dissecting the complex roles of the gut microbiota in health and disease.
