Objective

Objective 1: Investigate the use of selected probiotics, natural plant compounds, and bacteriophage, as potential alternatives to antibiotics and mechanisms to reduce the levels of Salmonella and Campylobacter in poultry. Evaluate these products in multiple production/processing systems including conventional, pasture raised, and organic systems. Sub-objective 1A: Reduce the incidence of Campylobacter in preharvest poultry by selecting probiotics that utilize mucin for growth and competitively inhibit Campylobacter colonization in broiler chickens. Sub-objective 1B: Reduce the incidence of Salmonella and Campylobacter in pre and postharvest poultry by utilizing plant extracts and other natural compounds such as chitosan, ß-resorcylic acid, naringenin and rutin hydrate. Sub-objective 1C: Reduce the incidence of Campylobacter in pre and postharvest poultry using mucin-adapted bacteriophage and genome targeting CRISPR-Cas system. Sub-objective 1D: Evaluate the genome wide effect of natural plant compounds and probiotics on Campylobacter especially genes critical for colonization in chicken using high-throughput deep sequencing of mRNA transcripts using RNA-seq. Objective 2: Develop innovative strategies for increasing disease resistance and improving immunity to foodborne pathogens of poultry using egg shell membrane technology. Sub-objective 2A: Determine effects of egg shell membrane on immune indices of chickens. Sub-objective 2B: Develop a proof of concept model for mucosal modulation of immunity by enriching HESM with Salmonella and Campylobacter.
