Effect of Genotype and Age on a Defined Microbiota in Gnotobiotic SCID Piglets

Katherine Marie Widmer, Faith M. Rahic-Seggerman, Ahlea Forster, Amanda Ahrens-Kress, Mary Ball Sauer, Shankumar Mooyottu, Akhil A. Vinithakumari, Aaron Dunkerson-Kurzhumov, Brett Sponseller, Matti Kiupel, Stephan Schmitz‐Esser, Christopher Keith Tuggle

The study tests the effect of microbiota complexity and age on gut microbiota stability in SCID piglets, finding age affects composition but not genotype, and the 7-strain consortium is most stable.
