Probiotic bacteria prevent Salmonella – induced suppression of lymphoproliferation in mice by an immunomodulatory mechanism

Table 1 Numbers of bacteria recovered from experimental mice

^aMice 1–4 were non-treated with probiotic lactic acid bacteria. Mice 5–8 were orally challenged with 1 × 10⁸ CFU probiotic bacteria mixture. Seven days later, all mice were orally challenged with 1 × 10⁸ CFU/mL S. enterica. ^bThe number of S. enterica isolated from feces of mice 7 days after challenge were enumerated on SS agar plates. ^cThe numbers of lactic acid bacteria were enumerated on MRS agar plates and reported as CFU/g feces 7 days after S. enterica challenge
