Figure 6. Effect of LCFM on intestinal cytokines after Salmonella enterocolitis.

Cytokine expression was analyzed by qPCR 2 days after oral inoculation with 3-4 x 10³ UFC of the pathogen. EC group: mice received 20 mg of streptomycin 24 h before intragastric infection with 3-4 x 10³ CFU of S. Enteritidis. L. casei + EC group: mice received the probiotic for a week before enterocolitis onset. Control group: untreated mice. L. casei + Strep group: animals were fed with the probiotic for a week and then received streptomycin. Results are expressed as mean +/- SD. Seven animals per group were analyzed. (NS): no significant differences. Representative data from 3 independent experiments.
