Abstract

 

The present study focused on the beneficial effects of Lactococcus lactis subsp lactis CNRZ 1427 with possible use as a therapeutic agent against Sal-monella sp.; also we have proposed different therapeutic possibilities of our situation against a pathogen Salmonella sp. We have conducted two tests In Vitro and In Vivo; where it is noted that treatment in the presence of this lac-tic strain is effective since it causes a remarkable decrease of the pathogen agent. At the end, the effectiveness of this lactic strain was confirmed by testing for resistance to gastrointestinal conditions (pH, bile salts and diges-tive enzymes).
