Technical Abstract: The intestinal microbiota are a complex mixture of microorganisms which significantly influence the development and function of the intestine. Altering the types and quantity of enteric microflora may enhance intestinal utilization of nutrients and reduce the colonization of food borne pathogens (e.g., Campylobacter). This is advantageous for both the poultry industry and consumer because birds will be cheaper to produce and the product less likely to provide a potential source of food borne illnesses. One strategy to achieve these goals is the use of probiotics. Probiotics are natural intestinal bacteria which, after oral administration, are able to establish and eventually colonize the digestive tract and prevent or reduce colonization of pathogenic organisms (i.e. competitive exclusion). Probiotics offer tremendous potential for enhancing enteric health and increasing nutrient utilization in poultry. Our team at the University of Arkansas has been working to develop novel in vitro techniques to select for enteric bacteria (probiotics) which reduce Campylobacter concentrating in the intestinal tract of poultry.
