Estimating the term…
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.
A method for the prophylaxis of intestinal disturbances in poultry caused by infections of pathogenic bacteria which comprises feeding to said poultry an effective amount of a bacterial preparation consisting essentially of at least four anaerobically co-cultured strains of normal alimentary tract bacterial species, said strains being chosen from those normally present in the alimentary tract of poultry, and each said strain being selected for having an adhesion efficiency onto the epithelial cells of the alimentary tract of poultry as determined by the Fuller adhesion test, of at least 10 bacteria per epithelial cell.
