Methicillin-resistant Staphylococcus aureus (MRSA) as the cause of infection is an increasing problem in both human and veterinary medicine. A 7-year-old intact male American cocker spaniel that had undergone removal of a nictitating gland was referred for severe ulcerative keratitis. Slit-lamp examination showed swelling of the eyelid, mucopurulent discharge, conjunctival injection and chemosis, diffuse corneal edema and opacity, and a deep ulcer in central cornea. Gram staining of discharge from the eye demonstrated Gram-positive cocci. Which therapy can be recommanded in such a bad case?
