Title:Interventions to Reduce Foodborne Pathogens in Swine and Cattle
Objective:1. Determine particular ecological niches/reservoirs for pathogenic/antimicrobial-resistant bacteria, identifying nutritional/biological/environmental factors affecting ability to colonize/survive/persist within gut of food-producing animals & their production environment. a) Determine effect of feeding distillers grains & other diets & organic acids on gut microbial ecology; b) Determine effects of feeding diets high in rumen undegradable intake protein & of feeding monensin on colonization/carriage/shedding of Campylobacter in cattle; c) Evaluate mechanistic effects of short chain nitrocompounds & free fatty acids on hydrogen balance/fitness of foodborne pathogens; d) Determine if specific or shared reservoirs exist for Clostridium difficile in populations of swine & humans in integrated agri-business operations; phenotypically/genotypically characterize Cl. difficile isolates; e) Determine effects of lactoferrin & whey-protein concentrate on fecal shedding & gut populations of Salmonella Typhimurium in weaned piglets; f) Determine influence of vitamin D supplement on fecal prevalence/concentrations of E. coli O157:H7 in cattle.

2. Evaluate ways to better characterize/control Salmonella, in particular multi-drug-resistant Salmonella, for use on commercial dairy farms to enhance food safety. a) Develop Salmonella serotype-specific real-time PCR method; b) Determine if Salmonella serotype changes due to changing environment or acquisition of antimicrobial resistance; c) Determine if feeding sodium chlorate, with/without nitroethane, is effective in reducing populations of Salmonella as well as E. coli O157:H7 & generic E. coli in milk-replacer fed calves & cull dairy cattle.

3. Develop interventions that prevent/mitigate colonization of gut of food-producing animals (particularly lower GI tract before slaughter) or that reduce pathogenic/antimicrobial-resistant bacteria in production environment. a) Determine if porcine-derived competitive exclusion culture can stimulate innate immune responses in neonatal gnotobiotic piglets; b) Develop/characterize bactericidal effectiveness of thymol & diphenyliodonium chloride products bound to clay-based adsorbents; c) Establish feasibility of fresh/dried citrus peel & purified essential oils as feed additives to reduce pathogen populations in ruminants; d) Develop targeted management interventions to facilitate exclusion of antimicrobial-resistant bacteria from gut of treated animals.

4. Develop understanding of microbial adaption to intrinsic/extrinsic stressors on acquisition/exchange/expression of incompatibility plasmids & antimicrobial resistance elements in foodborne pathogens in production/processing environments. a) Determine if number/size of plasmids possessed by different wildtype E. coli affects growth rate in nonselective & mixed culture environments, and if these plasmids are lost during long-term maintenance without selection pressure; b) Determine if IncN/Incl1 can mobilize IncA/C in tri-parental conjugations; c) Determine if occurrence of bacterial resistance to disinfectants is important in disinfectant control or impacts antibiotic resistance in microorganisms of animal origin.

Approach: Basic and applied research will be conducted to achieve project objectives. Ecological studies utilizing metagenomic analysis will elucidate niches or reservoirs where pathogens may exist and when combined with traditional epidemiological and microbiological cultural methods these studies will help reveal environmental, nutritional, and biological factors affecting fitness characteristics related to the persistent colonization, survival, and growth of these pathogens in food animals and their production environment. Research involving both in vitro and in vivo experimentation will be used to measure and characterize adaptive responses microbes may exhibit to intrinsic and extrinsic stressors, such as those exerted by disinfectants and antimicrobials, as well as to determine the role these stressors may play in pathogenicity, virulence, and resistance. Animal studies conducted under clinical and field situations will be used to develop and evaluate interventions, thereby revealing specific metabolic endpoints, cellular mechanisms, and sites of action of cellular processes that may ultimately be exploited to decrease carriage and shedding of pathogens during production and at slaughter. Opportunities for mitigation will be validated in the field. In some cases, Cooperative Research and Development Agreements will be implemented with industry partners to aid in technology transfer.
