Aging and Shared Household Are the Main Determinant of te Gut Microbial Similarity in Twins

Key Points

• To understand how aging and shared household environments affect the gut microbial similarity in twins.
• Analyzed gut microbiome samples from twins
• Compared microbial composition between cohabiting and non-cohabiting twins
• Assessed the influence of age and household type on microbial similarities
• Gut microbial profiles were more similar in twins living together than those apart
• Aging was correlated with specific changes in microbial diversity
• Shared household environment plays a significant role in microbial composition
