ABSTRACT:
The invention provides a bacterial preparation for the prophylaxis of intestinal disturbances, especially salmonella infections, in poultry, made by anaerobically cultivating either separately or together bacterial strains of normal alimentary tract bacterial species, optionally in the presence of epithelial cells from the alimentary tract, for example the crop of a poult, and isolating the cultivated bacteria from the nutrient medium and making a preparation of them, for instance by lyophilization. The only bacterial strains used are those having an adhesion efficiency onto the epithelial cells of the alimentary tract of the poult of at least 10 bacteria per epithelial cell.
