Pajau Vangay,Abigail J. Johnson,Tonya Ward,Gabriel A. Al-Ghalith,Robin R. Shields-Cutler,Benjamin Hillmann,Sarah K. Lucas,Lalit K. Beura,Emily A. Thompson,Lisa Till,Rodolfo Batres,Bwei Paw,Shannon Pergament,Pimpanitta Saenyakul,Mary Xiong,Austin D. Kim,Grant Kim,David Masopust,Eric C. Martens,Chaisiri Angkurawaranon,Rose McGready,Purna C. Kashyap,Kathleen A. Culhane-Pera,Dan Knights +23 more
TL;DR: Using 16S and deep shotgun metagenomic DNA sequencing, it is found that migration from a non-Western country to the United States is associated with immediate loss of gut microbiome diversity and function in which US-associated strains and functions displace native strains and functions.
Journal ArticleDOI
Effect of Diet on the Gut Microbiota: Rethinking Intervention Duration
TL;DR: Overall, further research on long-term diets that include health and microbiome measures is required before clinical recommendations can be made for dietary modulation of the gut microbiota for health.
Journal ArticleDOI
Daily Sampling Reveals Personalized Diet-Microbiome Associations in Humans
Abigail J. Johnson,Pajau Vangay,Gabriel A. Al-Ghalith,Benjamin Hillmann,Tonya Ward,Robin R. Shields-Cutler,Austin D. Kim,Anna Shmagel,Arzang N Syed,Personalized Microbiome Class Students,Jens Walter,Ravi Menon,Katie Koecher,Dan Knights +13 more
TL;DR: Data from two subjects consuming only meal replacement beverages suggest that a monotonous diet does not induce microbiome stability in humans, and instead, overall dietary diversity associates with microbiome stability.
Journal ArticleDOI
Longitudinal Multi-omics Reveals Subset-Specific Mechanisms Underlying Irritable Bowel Syndrome.

TL;DR: This study integrated longitudinal multi-omics data from the gut microbiome, metabolome, host epigenome, and transcriptome in the context of irritable bowel syndrome (IBS) host physiology to identify functional mechanisms that can serve as therapeutic targets in a comprehensive treatment strategy for chronic GI diseases.
Journal ArticleDOI
High-Fat Diet Changes Fungal Microbiomes and Interkingdom Relationships in the Murine Gut.
Timothy Heisel,Emmanuel Montassier,Abigail J. Johnson,Gabriel A. Al-Ghalith,Yi Wei Lin,Li Na Wei,Dan Knights,Cheryl A. Gale +7 more
TL;DR: A role for fungi and interkingdom interactions in the association between gut microbiomes and obesity is suggested, with evidence that ingestion of a high-fat diet is associated with changes to the fungal (and bacterial) microbiome in a mouse model.
