Effects of B. breve A1 on contextual fear extinction in mice. Mice were given oral administration of living B. breve A1 at a volume of 0.2 mL (1 × 109 cfu organisms suspended in saline) or saline for 4 days from 3 days before the conditioning day. Data are expressed as the mean ± SEM; n = 6–7. a p < 0.05 vs. MPTP + Saline on Day 1, b p < 0.05 vs. Control + Saline on Day 1, c p < 0.05 vs. Control + B. breve A1 on Day 1, d p < 0.05 vs. MPTP + B. breve A1 on Day 1, and * p < 0.05: between MPTP + Saline and MPTP + B. breve A1 on Day 3.
