Plain-English summary
A study found that many dogs with eye problems had a type of bacteria called Staphylococcus pseudintermedius that was resistant to common antibiotics, including fluoroquinolones and methicillin. Out of 49 samples tested, about 40% showed resistance to several fluoroquinolones, which are often used to treat infections. This resistance was more common in dogs with eye issues compared to those without. The findings suggest that if your dog has an eye infection, it may be important to discuss antibiotic options with your vet, as some bacteria may not respond to standard treatments.

Abstract
Resistance to fluoroquinolones and methicillin was determined for 49 ophthalmic isolates of Staphylococcus pseudintermedius from dogs with and without ophthalmic disease. Resistance was observed for ciprofloxacin (40.8%), ofloxacin (38.8%), enrofloxacin (38.8%), levofloxacin (34.7%), and moxifloxacin (4.1%). Eighteen isolates, 16 of which were resistant to oxacillin, were mecA-positive. Nine of the 16 oxacillin-resistant mecA-positive S. pseudintermedius isolates were resistant to more than one fluoroquinolone and 2 isolates were resistant to 5 fluoroquinolones. The frequency of mecA gene occurrence and fluoroquinolone resistance was twice as high among S. pseudintermedius isolates derived from dogs with ophthalmic disease compared with isolates for dogs without ophthalmic disease. The high prevalence of methicillin and fluoroquinolone resistance in S. pseudintermedius from dogs with ophthalmic disease is a concern.
