This study carried out to investigate the antimicrobial resistance and biochemical characteristics of Staphylococcus aureus (S. aureus) isolated from reproductive and respiratory tract in Thoroughbred horse. The specimens were collected from equine vaginal mucosa and upper respiratory tract from March to December 2006 using a culture swab in Korea. S. aureus suspected colonies on blood agar plates were selected and identified as standard biochemical tests and PCR (Applied Biosystems, USA). Antimicrobial resistance test of S. aureus isolates was performed with 30 antimicrobial agents (BBL, USA) by using the agar disk diffusion method. S. aureus isolates were isolated 58 (39.2%) strains of 148 samples: wound 64.7% (11/17), genital discharge 37.0% (37/100) and nasal discharge 32.2% (10/31). Almost isolates showed high resistance to spectinomycin, sulfonamides, erythromycin, tetracyelin, ciprofloxacin and penicillin. These results may provide the basic information to establish strategies for treatment and prevention of reproductive and respiratory disease in Thoroughbred horses in Korea.
