Neonatal EPEC infection impairs hippocampal neurogenesis in adulthood. (A) Confocal imaging was used to assess neurogenesis via quantification of cell proliferation (Ki67) (red) and immature neurons (doublecortin [DCX]) (green). Bars = 100 μm. (B) Quantification of Ki67⁺ and DCX⁺ cells per cubic micrometer in the dentate gyrus (DG) (n = 5 mice per group) (*, P ≤ 0.05 [by Student’s t test]). (C) Relative mRNA expression of Bdnf in the hippocampus (n = 16 mice per group) (*, P ≤ 0.05 [by Student’s t test]).
