Objective To retrospectively analyze the clinical distribution and changes in antimicrobial resistance profiles of Staphylococcus aureus (S. aureus). Methods We collected clinical specimens of S. aureus from The First Hospital of China Medical University. The Vitek-2 and BD Phoenix 100 were performed for bacterial identification and drug sensitivity tests,and WHONET 5.6 was used to analyze the data. Results From 2007 to 2016,there were 3 377 unrepeatable strains of S. aureus,including 1 705 that were methicillin resistant S. aureus (MRSA). The isolation rate of S. aureus was 9.4 ％ and of these,50.5 ％ were MRSA. There were 776 S. aureus specimens from outpatients or the emergency department,including 16.8 ％ MRSA,and 2 011 S. aureus from inpatient departments,including 60.2 ％ MRSA. The main sources of specimens were sputum (41.8 ％),pus (17.9 ％),and body secretions (17.5 ％). The average resistance rates of MRSA for erythromycin,ofloxacin,ciprofloxacin,gentamycin,and tetracycline were higher than 75.0 ％. The average resistance rate of methicillin sensitive S. aureus (MSSA) for erythromycin was up to 76.8 ％,and for tetracycline,gentamycin,ciprofloxacin,and ofloxacin,were less than 25.0 ％. In 10 years,the average resistance rates of MRSA and MSSA for 11 kinds of common antibiotics had no obvious change. Conclusion The constituent rate of MRSA was high in The First Hospital of China Medical University,especially from the areas that were not sterile,suggesting that clinicians should pay attention to the identification of infection and sources for MRSA,which were from such areas. Hospital infection control should be focused on at the same time,in order to reduce the incidence of MRSA.
