Staphylococcus aureus, which is generally susceptible to the involvement route in community, is mostly MSSA. However, CA-MRSA is recently increased. Abuse of antibiotics and glycopeptides may increase VISA and VRSA. This study was conducted to investigate the changes on the antibiotic resistance prevalence and antibiotic susceptibility patterns of Staphylococcus aureus isolated from the wound of patients in a university hospital for the past 10 years. This study showed that antibiotic resistance was higher in males than in females; moreover, the antibiotic resistance rates increased with age. The resistance rate for penicillin, oxacillin, erythromycin, gentamicin, clindamycin, tetracycline, ciprofloxacin, fusidic acid, trimethoprim/sulfamethoxazole, clindamycin, and rifampicin was, respectively, 97.7%, 60.5%, 57.4%, 48.8%, 41.1%, 44.2%, 44.2%, 14.7%, 13.2% and 3.9% in 2006. The resistance rate for penicillin, oxacillin, erythromycin, gentamicin, clindamycin, tetracycline, ciprofloxacin, fusidic acid, trimethoprim/sulfamethoxazole, fusidic acid, clindamycin, and rifampicin was, respectively 95.9%, 62.6%, 55.7%, 28.6%, 50.3%, 34.7%, 38.8%, 34.0%, 2.7% and 8.2% in 2016. Vancomycin, linezolid, quinupristin/dalfopristin, and teicoplanin exhibited 100% in antibiotic susceptibility. In particular, fusidic acid resistance was increased by 19.3% in 2016. Compared with 2006, the decreased point, 12.4% was susceptible and was statistically significant. Therefore, this study suggests that periodic review and understanding of microbial and antibiotic changes should continue to investigate appropriate antibiotic susceptibility.
