So far, the researchers have found more than 80 horses — and 25 people in contact with horses — that have tested positive for the MRSA bacteria. “Through this research, we hope to determine the scope of MRSA infection in horses and people who work with horses,” says Weese. “We want people to understand the risks associated with MRSA infection both for other horses and for people and to find an alternative way for equine practitioners to treat MRSA carriers.”
He says information about MRSA cases has come to him from veterinarians across North America. He believes MRSA infection in horses is under-reported because there’s little information available about the risks of transmission and how to handle affected horses.
