Gut microbiota in ETEC induced diarrhea. a The jejunal microbiota at the phylum level among controls, diarrheal piglets, recovered piglets and resistant piglets were analyzed using metagenomics. b The jejunal microbiota at the genus level were analyzed using metagenomics. c The jejunal microbiota at the species level were analyzed using metagenomics. d The jejunal microbiota at the phylum level among controls, diarrheal piglets and resistant piglets were analyzed using 16S rRNA sequencing. e The jejunal microbiota at the genus level were analyzed using 16S rRNA sequencing. f The fecal microbiota at the phylum level among controls, pre-diarrheal piglets, and resistant piglets were analyzed using 16S rRNA sequencing. g Real time-PCR analysis of the relative abundance of Bacteroidetes and Firmicutes in the feces among controls, pre-diarrheal piglets, and resistant piglets (n = 6; *: p < 0.05, one-way ANOVA). h The fecal microbiota at the genus level were analyzed using 16S rRNA sequencing. N = 3 before pooling for a, b, c; and n = 4 before pooling for d, e, f, h
