Interpretive Summary:

Technical Abstract: The intentional early colonization of the intestinal tract with beneficial microflora, known as competitive exclusion, has been shown to successfully protect poultry from selected enteric pathogens. While effective cultures have been produced and are available, an inexpensive, air tolerant and completely defined culture is needed. Presently, we developed an in vitro competition assay to select for individual facultative anaerobes, of poultry enteric origin, that could exclude Salmonella and/or Campylobacter. Using combinations of prebiotics selected to out complete these pathogens in vitro, our laboratories have demonstrated that these relatively simple defined cultures consisting of air-tolerant bacteria can inhibit Salmonella and Camplyobacter colonization in chicks and poults.
