Identification and Antimicrobial Drug Susceptibility of Clinical Staphylococcus spp. Isolates from Canine Superficial Pyoderma at a Primary Veterinary Hospital

Abstract

Staphylococcus spp. was isolated from 20 dogs with superficial pyoderma at a primary veterinary hospital. Among the 20 isolates, 19 Staphylococcal strains were identified as S. pseudintermedius and one as S. schleiferi. The 20 isolates had three (15%) positive for mecA gene. Typing of Staphylococcal cassette chromosome mec (SCCmec) revealed all carried type V SCCmec. The mecA-positive S. pseudintermedius showed resistance to a variety of antimicrobial agents other than β-lactams indicating multiple-drug resistant phenotype. Our results strongly suggest primary veterinary hospital clinicians should consider the possibility of mecA-positive S. pseudintermedius as an etiologic agent of canine pyoderma.
