Antibiotic use in veterinary medicine: Antimicrobial are used extensively in animals, and their use can contribute to the development of antimicrobial resistance. Dr. Redding is interested in better understanding how antibiotics are used in veterinary settings, discerning the clinical and One Health implications of their use and developing ways to refine their use.


The animal reservoir of Clostridium difficile: Clostridium difficile is the leading cause of antibiotic-associated and nosocomial diarrhea in humans and a significant enteric pathogen in many species of animals. It is generally accepted that the administration of antibiotics is the primary risk factor for the development and recurrence of C. difficile infection. However, patients can develop infections with C. difficile outside of a healthcare facility without the prior use of antibiotics. Dr. Redding is interested in studying whether animals - particularly companion animals - can serve as a reservoir for C. difficile infections in people.
