Dr. Todd Callaway is a ruminal and gastrointestinal microbiologist and has studied the microbial ecology of food safety extensively. He has authored or co-authored more than 250 peer-reviewed journal articles, 40 book chapters, 50 conference proceedings, 25 magazine and technical publications, more than 200 abstracts, and edited 2 books along with more than 200 scientific presentations around the world. Todd has researched how ruminal bacteria become resistant to the ionophore monensin which has been critical to understanding how the microbial ecosystem within the gastrointestinal tract of cattle can be changed. His research has also elucidated methods to reduce E. coli O157:H7 and Salmonella shedding in cattle. His research pioneered new techniques to determine how diet impacts the microbial population of the gut and in turn endproducts that affect the nutritional status of the ruminant animal. |
