Antibiotic Alternatives Working Group

Members of the Antibiotic Alternatives Working Group are interested in identifying alternatives to the nontherapeutic use of antibioticsin the raising of food animals such as cattle, poultry and swine. Low doses of antibiotics are commonly used to promote the growth of food-producing animals in addition to the therapeutic doses used to prevent, control and treat disease. Overuse of antibiotics is believed to be related to the appearance of antibioticresistant bacteria in the food supply, with the resistant pathogens ultimately cause resistant infections in humans. For example, one possibility to be used as an antibiotic alternative is a probiotic.

Dr. Emefa Monu is an assistant professor in poultry science and studies food microbiology. Specifically, she conducts research on alternatives to reduce pathogenic and spoilage bacteria and fungi in food. This includes natural antimicrobials derived from plants and bacteria. She has an ongoing collaboration with the Food and Drug Authority in Ghana to provide training/workshops for their Food Enforcement Officers and help develop food safety training for food entrepreneurs.

Stephanie Ostrowski, DVM, is an associate professor of public health in the Auburn University College of Veterinary Medicine. She teaches classes on environmental health and food safety (from farm to fork).  She is program lead for the DVM + MPH dual degree, and co-coordinates and team-teaches three of the four courses in Auburn’s interdisciplinary undergraduate minor in public health along with Dr. James Wright. Dr. Ostrowski’s clinical academic training includes two residencies at the University of California-Davis, one in herd health and food animal production medicine (1984-87) and a second in food safety (2010-2012), where she evaluated sample submission logistics for rapid threat identification and response for the California dairy industry. In 2010, Dr. Ostrowski retired from the Centers for Disease Control and Prevention after 20 years of service, having achieved the rank of captain in the U.S. Public Health Service. During her CDC career, she served as senior emergency response coordinator for the Agency for Toxic Substances and Disease Registry and for the National Center for Environmental Health with participation in federal public health emergency preparedness and response for CBRNE (chemical, biological, radiological, nuclear, and explosives) as well as natural disaster events. These incidents ranged from anthrax attacks and Twin Towers/9-11, and from hurricanes and tsunamis to the British Foot and Mouth Disease emergency. Dr. Ostrowski’s current research interests include public health/one health, global sustainability of livestock agriculture, food safety and security, toxicology, and veterinary infectious diseases.

pricesb@auburn.edu / 334-844-2673

Dr. Stuart Price is a bacteriologist in the College of Veterinary Medicine who works with the zoonotic foodborne pathogen Salmonella.  His lab investigates the use of pathogen-targeted bacteriophages as living antimicrobials for use as alternatives to antibiotic use in food animals. The goal is to utilize bacteriophages along with other natural antimicrobials to inhibit pathogen growth in animals, without concomitantly increasing the selection of antibiotic resistant pathogens in the food animal microbiome.

Sarah Zohdy is an assistant professor of disease ecology in the School of Forestry and Wildlife Sciences. Her lab focuses on the ecological and evolutionary drivers of disease dynamics. She is interested in how host ecology, behavior, and physiology influence heterogeneity in parasitism at the population level. In order to effectively evaluate disease dynamics at the ecosystem level, her lab takes an interdisciplinary approach and combines methodologies to better understand how land-use change affects the ecology of infectious diseases.
