Teaching Program
ANSC 66000 Intestinal Microbiology and Immunology
Discussion and critique of recent journal articles related to intestinal microbiology/immunology. The specific areas covered under this forum are: (i) Intestinal microbiology and microbiome, (ii) Food microbiology as it related to gastrointestinal diseases and persistence, (iii) Probiotics and prebiotics - related to intestinal health or pathogen control, and (iv) Mucosal immunity with major emphasis on intestinal immunology and gut health. 

We are discovering key processes and interactions in the animal microbiome, finding alternative growth promoters to antibiotics, and working to maintain food safety in meat products to the public. Our lab has two research goals: 1) to understand the diverse impacts of antimicrobial use in agriculture on microbial communities and antibiotic resistant genes, and the sustainability of these impacts; and 2) to manipulate the microbiome to improve nutrition and health in food animals, largely poultry and swine.
