Antibiotic treatments of a methicillin-resistant Staphylococcus pseudintermedius infection in a dog: A case presentation

We report the antibiotic treatments administered to a female dog with mastitis and successive pyoderma. Microbiological investigations allowed the identification of Staphylococcus pseudintermedius after 54 days of various antibiotic treatments. The isolate carried the mecA gene and was resistant to 9 of 15 tested antibiotics. Consistent antibiotic treatment of the infection was possible only after accurate microbiological diagnosis
