T7 phage represses the E. coli level without affecting the physical conditions and the overall population of gut bacteria

(A) The schematic diagram of the time frame and the behavioral tests employed in this study (n = 12 for each group). OFT, open-field test; RSIT, reciprocal social interaction test; TCST, three-chamber sociability test; EPM, elevated plus-maze test; NOR, novel object recognition test; NSF, novelty-suppressed feeding test; TST, tail suspension test.

(B) Physical conditions: body weight (left, mean ± SD), daily water intake (middle, mean ± SD), and daily food intake (right, mean ± SD) measured for each group (n = 12) at different times.

(C) The level of E. coli (left, mean ± SD) and the level of total bacteria (right, mean ± SD) quantified by qPCR over time (n = 12 for each group).
