L. monocytogenes adhesion to and invasion of HT-29 cells in the presence or absence of P. acidilactici BLs. HT-29 cells were pretreated with K10 BL (A,C) or HW01 BL (B,D) (0, 20, 40, and 80 μg/mL) for 3 h, after which L. monocytogenes (1 × 107 CFU/mL) was added and incubated for 1 h. Adhesive and invasive abilities of L. monocytogenes were determined by plating samples on BHI agar. The results are represented as the means ± standard deviations from three independent experiments (p < 0.05). Significant differences between treatment with K10 BL or HW01 BL are expressed with different letters (a–d).
