Inhibitory Effects of Chick Lactobacilli on Enteropathogenic Salmonella

Abstract: The major source of human salmonellosis are farm animals, which may frequently be intestinal carriers of the organism. Lactobacilli isolated from the intestinal tract with efficiency adhesion were selected and studied in assay competitions with different Salmonella serotypes. The growth and lectin production of lactobacilli remained unchanged in several mixed and single culture studies. However, in mixed cultures, the inhibition (bacteriostatic) of viable bacteria of salmonella strains was observed. The adhesion ratio showed significant values for L. animalis, L. fermentum, S. Gallinarum and S. Pullorum. These results indicate the remarkable importance of a specific host interaction in the colonization process by microorganisms. L. animalis was effective in reducing the attachment of S. Gallinarum, S. Pullorum and S. Enteritidis to host-specific epithelial cells, while L. fermentum was able to reduce the attachment of S. Pullorum and S. Gallinarum. Therefore, we suggest that chicken lactobacilli included in this work may be considered potential probiotic microorganisms, and used in the preparation of a probiotic food.
