Abstract:
AIM: To investigate the antimicrobial activity of linezolid,vancomycin and other antibacterials against 111 methicillin resistant staphylococcus aureus.METHODS: Broth dilution method was used to determine the minimum inhibitory concentrations(MICs) of linezolid,vancomycin and other antibacterials against 111 methicillin resistant staphylococcus aureus identified by cefoxitin.RESULTS: The resistant rates of 111 MRSA to ?-lactam,erythromycin,aminoglycosides(netilmicin and gentamycin),fluoroquinolones(gatifloxacin,moxifloxacin and levofloxacin) and chloromycin were 100%,92.8%,99.1%,91.9%-99.1%,3.6%.All 111 MRSA were sensitive to linezolid and vancomycin,and MIC50 and MIC90 of vancomycin were 0.5 and 1 ?g/mL,MIC50 and MIC90 of linezolid were 2 ?g/mL.CONCLUSION: 111 MRSA were resistant to most antibacterials including ?-lactam,erythromycin,aminoglycosides and fluoroquinolones.Linezolid and vancomycin have strong antimicrobial activity against MRSA.
