¹ Significant differences between operational taxonomic units (OTUs) at 1 vs. 7 days post-inoculation (dpi) within each subgroup (p < 0.05). Subgroups: S-I (negative control), S-II (Salmonella enterica serovar Enteritidis (SE) challenge), S-III (Intebio^® intake), and S-IV (Intebio^® intake + SE challenge). ^a,b Data within one column with no common letters differed significantly (at p < 0.01). OTUs: operational taxonomic units.
