Protection of young chicks against Salmonella kedougou by administration of intestinal microflora.
One-day old chickens were treated with a faecal suspension and faecal samples were cultivated either in non-selective broth (Viande Levure broth) or in broths selective for Lactobacillus spp., Bacteroides spp., faecal enterococci and coliforms. The chickens were infected 48 h later with 10(4) colony-forming units of nalidixic-acid resistant Salmonella kedougou and examined seven days later. Faecal suspensions and faecal samples cultivated in non-selective broth exerted a protection against Salmonella infection; no protection was obtained with faecal samples cultivated in selective broths, administered either alone or in combination.
