Antibiotic sensitivity of bacterial isolates from cases of canine dermatitis.

Among 97 bacterial isolates, 74 strains of Staphylococcus spp developed from 95 swabs taken from skin lesions in dogs. Twenty-eight staphylococcal strains resistant to methicillin and/or oxacillin were identified and mecA expression was confirmed for 14 of these strains. S. aureus and S. intermedius group (SIG) strains were particularly relevant in our cases due to their antibiotic resistance leading to an increased veterinary and public health risk. We suggest a diagnostic protocol based on cytological examination, bacterial identification to species level, and antibiotic sensitivity testing prior to prescribing antibiotic treatment for canine skin diseases.
