16S rRNA gene amplicon sequencing of intestinal microbiota in piglets administered Bacillus subtilis DB9011
This BioProject contains 16S rRNA gene amplicon sequencing data generated to evaluate the effects of Bacillus subtilis DB9011 administration on the intestinal microbiota of piglets. Two independent animal studies were conducted. In the first study, piglets were administered DB9011 under commercial farm conditions, and bacterial communities in rectal swab samples were analyzed. In the second study, gnotobiotic piglets were administered DB9011, and bacterial communities in ileal, cecal, and colonic contents were analyzed. These datasets were used to assess changes in intestinal microbial community composition and diversity associated with DB9011 administration across different experimental settings and intestinal sites.
