Colony-forming units (CFU) of B. animalis subsp. lactis BB-12 (BB12) in the gnotobiotic piglets. BB12 CFU was counted in the jejunum, ileum, colon, and blood (all CFU/mL) and mesenteric lymph nodes (MLN), liver, spleen, and lungs (all CFU/g) in the piglets monoassociated with BB12 (BB12; blue column) and the piglets monoassociated with BB12 and one week later infected with S. Typhimurium LT2 for 24 h (BB12 + LT2; violet column). Interferences between BB12 and LT2 were evaluated by unpaired t-test, and statistical differences were marked with asterisks at p < 0.05. Log CFU are depicted as mean + SEM and n = 6 piglets for all groups.
