The effect of lactobacilli on the adhesion of C. perfringens to cells and the cytotoxicity induced by C. perfringens. Cells were pretreated with L. acidophilus or L. fermentum with multiplicity of infection (MOI) at 10 for 3 h and then infected with C. perfringens (MOI = 1) for 1 h. The percentage of C. perfringens adhered to cells were calculated (A) and LDH levels in the cell culture medium were detected (B). Data are presented as mean ± standard error (n = 3). ^*P < 0.05; ^**P < 0.01. La, L. acidophilus; Lf, L. fermentum; Cp, C. perfringens.
