Drug Resistance of 312 Staphylococcus aureus strains / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To study the antimicrobial agents resistance of Staphylococcus aureus isolated from clinic.METHODS To test the sensitivity of 20 common antimicrobial agents by K-B.MRSA was detected by cefoxitin disk;and the inducible resistance of clindamycin was detected by D-test.RESULTS The drug resistance rate of this term of S.aureus was high.Except vancomycin,minocycline,teicoplanin,nitrofurantoin and rifampin,the drug resistance rate was higher than 42.6%.From 312 strains of S.aureus 209 strains of MRSA were detected,the rate was 67.0%.The structural antimicrobial resistance rate of clindamycin was 29.5%,the detection rate of inducible resistance was 51.4%.CONCLUSIONS The antimicrobial resistance of S.aureus is increasingly severe.The high positive results of MRSA and D-test make great trouble to therapy,and should have taken more attention of clinic.
