Abstract

Staphylococci are Gram-positive, facultatively anaerobic cocci, normally found on the skin andmucosal surfaces of most warm-blooded animals and often involved in a wide variety of diseases in animals.Staphylococcal infections are treated with antibiotics and, consequently, antibiotic resistance and/or acquiredresistance have developed. Staphylococcus (S.) intermedius and Staphylococcus (S.) aureus are 2 comonveterinary isolates that are frequently associated with suppurative infections. This study was undertaken toexamine antimicrobial susceptibility of S. aureus (23 isolates) and S. intermedius (160 isolates) isolatedfrom dogs in Gwangju, Korea and investigate whether the antibiotic resistance of S. aureus and S.intermedius is efected by the site of isolation, age, and sex of dogs. More isolates were isolated fromadult dogs (71.3%) than juveniles (20.5%). Antimicrobial resistance was commonly found for Penicillin,Tetracycline, Trimethoprim-Sulphamethoxazole in both Staphylococcus species. All of the isolates weresusceptible to Amoxicillin/Clavulanic Acid, Cephalothin, Oxacilin, Neomycin, and Vancomycin. Appropriateprotocol for antibiotic use and strategies to reduce antimicrobial resistance rate will be needed. Periodicsubstitution of antimicrobial agents and limitation of antibiotic use should also be considered.
