Fecal microbiota transplantation modulates jejunal host-microbiota interface in weanling pigletsOriginal paper
Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease, four years before the first published case study.

Researchers tested whether fecal microbiota transplantation (FMT) could reshape the jejunum, an understudied gut segment central to postweaning diarrhea in piglets. Thirty two 3 week old piglets were split into Control and FMT groups.
How was it studied?
FMT piglets received fecal microbiota from healthy 3 month old pigs on days 1 and 3 after weaning. Half of each group was later challenged with enterotoxigenic E. coli (ETEC), and jejunal tissue and contents were analyzed by microbiomic, metabolomic, and transcriptomic methods in week three.
What did they find?
FMT raised jejunal alpha diversity and enriched genera including Pseudoscardovia, Solobacterium, Shuttleworthia, and Pseudoraminibacter, while Erysipelotrichaceae and Acidaminococcus dominated in controls. FMT also shifted carbohydrate, amino acid, and vitamin metabolism, altered immune and barrier gene expression, and reduced diarrhea severity after ETEC challenge, though pathogen shedding was unchanged.
Why it matters
The findings suggest FMT could support jejunal health and help address small intestinal dysbiosis in swine, with possible relevance to humans and other monogastric species sharing similar gut anatomy.
