A strain of methicillin-resistant Staphylococcus aureus commonly associated with livestock has emerged as the main cause of MRSA infection in horses in some areas of Europe, and horses could facilitate the spread of the pathogen. ST398, as it is called, is believed to have originated in humans but has been found in pigs, cattle, poultry and now horses. In horses, infection manifests at surgical sites, in the lungs as pneumonia, at catheter sites and more. Horse owners and veterinarians should take basic precautions to help prevent the spread of the bacteria.
