Mouse gut microbiota significantly impacts research outcomes, yet knowledge remains fragmented. Standardizing the gut microbiome is crucial for reliable translational medical research using laboratory mice.
Area of Science:
- Microbiology
- Immunology
- Genetics
Background:
- Laboratory mice are vital for translational research.
- Gut microbiota influences host physiology and disease.
- Variability in mouse phenotypes is linked to microbiota differences.
Purpose of the Study:
- To summarize mouse gut microbiota diversity and functions.
- To review gnotobiotic mouse models.
- To discuss future research directions.
Main Methods:
- Literature review of mouse gut microbiome studies.
- Analysis of data on microbiota diversity and function.
- Examination of gnotobiotic mouse model research.
Main Results:
- Significant impact of gut microbiota on mouse phenotypes.
- Discrepancy between mouse model usage and microbiome knowledge.
- Variability in microbiota across different research facilities.
Conclusions:
- Understanding mouse gut microbiome is critical for research reproducibility.
- Gnotobiotic models offer insights into host-microbe interactions.
- Further research is needed to standardize mouse gut microbiome studies.
