Abstract :

Among the food additives used in animal production, highlight the probiotics which are beneficial to the health of the host and do not promote drug resistance. In this context, this study aimed to characterize lactic acid bacteria isolated from feces of young foals for use as probiotics in food supplementation and growth promotion. An isolate of Pediococcus pentosaceus fully complied all of the requirements established for in vitro functional characterization and was chosen for in vivo tests. The weight gain from dietary supplementation of conventional mice with an isolated Pediococcus pentosaceus challenged or not with S. typhimurium was evaluated in order to check the influence of this treatment on animals. To verify the safety of this treatment, we compared liver and spleen indices and mortality rate of all groups. Only the group treated and challenged with S. typhimurium did not show a tendency to gain weight. Oral administration of an isolated Pediococcus pentosaceus in the mice was not able to increase the survival rate of infected animals. The spleen and liver indices demonstrated that this treatment does not promote a significant increase (p>0.05) in the size of these organs compared to control animals. Statistical difference was observed (p<0.05) only when the indices are compared between controls and challenged groups. Treatment with these P. pentosaceus isolate was proved to be safe but was not an appropriate therapy against S. typhimurium infection, because it did not cause any weight gain and increased survival rate of animals infected.
