PROCEDURE FOR THE PREPARATION OF AN ESSENTIAL PATHOGENEOUS BIRTHS MICROFLORA WITH A CAPACITY TO PREVENT LATE INFECTION OF PARATYPHUS SALMONELLA

摘要

The invention resides in a mixture of avian intestinal microflora for administration to poultry to prevent or inhibit paratyphoid salmonella infection including infection by the arizona groups in the poultry or in the presence of infection to reduce the incidence and excretion rate of paratyphoid salmonella. The mixture is obtained by transferring, to newly hatched pathogen-free poultry, starting avian microflora known to be capable of blocking subsequent colonization, recovering said microflora from the faecal droppings of said pathogen-free poultry in a manner precluding subsequent contamination by pathogens, and recovering the pathogen-free microflora from the faecal droppings of said poultry.
