The antibacterial activity expressed in vitro and in vivo by Lactococcus lactis subsp. lactis CNRZ 1427 against Salmonella sp.

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).
