Three new Lactobacillus plantarum strains in the probiotic toolbox against gut pathogen Salmonella enterica serotype Typhimurium
The benefits of probiotic bacteria are widely explored. However, the research is not over and we present three new Lactobacillus plantarum strains isolated from different dairy products - cow cheese, sheep cheese and whey. In order to determine the antibacterial activity of yet unexplored Lactobacillus plantarum strains – A, B and S1, against Salmonella enterica serotype Typhimurium in vitro competition and co-culture tests were done. Furthermore, adhesion of these strains to Caco-2 cells and their influence on the adhesion of Salmonella were tested. Results showed the potential probiotic activity of isolated strains. They survive in the presence of 1% bile salts ; possess acidification ability, as well as antibacterial activity - reducing the number of S. Typhimurium. All tested L. plantarum strains were able to adhere to Caco-2 cells and significantly impair the adhesion of S. Typhimurium. They exhibited significant probiotic potential and anti-Salmonella activity, further testing on in vivo models should follow.
