Diarrheal diseases, commonly called scour, are common in newborn ruminant farm animals including deer fawns. The clinical presentation can range from mild diarrhea without systemic disease to profuse, acute diarrhea associated with rapid dehydration and death, sometimes within hours of onset. Determining the particular agents associated with an outbreak of diarrhea is important for both prevention and treatment. This 5-page fact sheet written by Juan M. Campos Krauer and Samantha M. Wisely and published by the UF/IFAS Department of Wildlife Ecology and Conservation focuses on disease in fawns caused by pathogenic types of Escherichia coli, describes the pathogens and how they infect fawns, and includes advice about treatment and prevention.
