Abstract:
Objective To analyze the antimicrobial resistance of Staphylococcus aureus isolated from clinical samples.Methods Staphylococcus aureus and methicillin-resistance Staphylococcus aureus were collected in the microorganism lab from 2004 to 2008,and the antimicrobial susceptibility test was conducted by disk diffusion technique(K-B method).Results A total of 1521 Staphylococcus aureus were collected in 5 years,of which 890 were MRSA(58.5%).Of all the SAU strains,255 were isolated from emergency room(16.8%),201 from surgery wards(13.2%)and 171 from surgical intensive care unit(SICU)(11.2%).Of all the MASA strains,199 were collected from emergency room(22.4%),148 from SICU(16.6%)and 131 from RICU(14.7%).Most of the MRSA strains(725,81.5%)were isolated from sputum,and the others from wound secretions(62,14.7%),blood(27,3.0%),throat(17,1.9%)and urine(16,1.8%),etc.MASA was resistant to most antibiotocs,but quite sensitive to SMZ.No strains resisted to vancomycin or teicoplanin were found in this study.MASA from all the departments showed a feature of highly resisting to variety antibiotics.Conclusion SAU,especially MASA were increasing in the past 5 years in our hospital.MASA was resistant to 90% of the ? lactan,macrolides and quinolones.No strains resistant to vancomycin or teicoplanin were found yet.It is of great value to monitoring the antimicrobial resistance of SAU and MRSA during the clinical practice.
