Differentially expressed indicator genus in the P and S groups.

Study	Differentially expressed genus in the P group compared with the S and N groups (P < 0.05)	Differentially expressed genus in the S group compared with the P and N groups (P < 0.05)
Growing turkey; 2-d PI	Genus with increased abundance Subdoligranulum Faecalibacterium Genus with decreased abundance Streptococcus	Genus with increased abundance Turicibacter
Growing turkey; 7-d PI	No differentially expressed indicator genus were identified.	Genus with increased abundance Turicibacter Gordonibacter Flavonifractor Streptococcus
Finishing turkey; 2-d PI	Genus with increased abundance Lactobacillus Ruminococcaceae_NK4A214_group Ruminococcaceae_UCG.010	Genus with increased abundance Turicibacter
Finishing turkey; 7-d PI	Genus with increased abundance Lactococcus Erysipelatoclostridium Leuconostoc Butyricicoccus	Genus with increased abundance Turicibacter Streptococcus

N, Negative control (turkeys without SH challenge or PF supplementation); S, SH control (turkeys challenged with SH without PF supplementation); P, (turkeys supplemented with PF and challenged with SH). 2-d PI and 7-d PI indicate 2- and 7-d postinoculation samples, respectively.

Abbreviations: PF, Propionibacterium freudenreichii; SH, Salmonella Heidelberg.
