Methicillin resistance was determined by studying the minimum inhibitory concentration (MIC) of oxacillin (HI media, Mumbai) by macrobroth dilution method (dilutions ranging from 0.25 [micro]g/ml-256 [micro]g/ml).
The MIC values of all the isolates for vancomycin by macrobroth dilution method were in the susceptible range (breakpoint [less than or equal to] <4 [micro]g/ml) and 86.15% (112/130) exhibited MIC [less than or equal to] 0.5 [micro]g/ml.
