Abstract

Abstract O 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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 59 words
A process for the manufacture of a bacterial preparation for the prophylaxis of intestinal disturbances in poultry, which comprises anaerobically cultivating separately or together bacterial strains of normal alimentary tract bacterial species having an adhesion efficiency onto the epithelial cells of the alimentary tract of poultry of at least 10 bacteria per epithelial cell, and isolating the cultivated bacteria.
Claim 2
Dependent Claim 59 words
A process for the manufacture of a bacterial preparation for the prophylaxis of intestinal disturbances in poultry, which comprises anaerobically cultivating separately or together bacterial strains of normal alimentary tract bacterial species having an adhesion efficiency onto the epithelial cells of the alimentary tract of poultry of at least 10 bacteria per epithelial cell, and isolating the cultivated bacteria.
Claim 3
Dependent Claim 24 words
A process according to Claim 1 in which the bacteria are cultivated in the presence of epithelial cells from the alimentary tract of poultry.
Claim 4
Dependent Claim 13 words
A process according to Claim 1, wherein 4-8 different bacterial strains are cultivated.
Claim 5
Dependent Claim 18 words
A process according to any one of Claims 1 to 3, wherein the bacterial strains are cultivated together.
Claim 6
Dependent Claim 18 words
A process according to any one of Claims 1 to 4 wherein the selected bacterial strains are Lactobacilli.
Claim 7
Dependent Claim 22 words
A process according to any one of Claims 1 to 4 wherein the selected bacterial strains are both Lactobacillus and Clostridium species.
