<prompt> Staphalococcus Oxacillin resistance is best detected by?Cefotixin MICCefotixin disc diffusionOxacillin disc diffusionOxacillin agar  <response>: Ans. is b i.e., Cefotixin disc diffusionOxacillin also methicillin resistance is detected by finding the presence of mec A gene.Cefoxitin disc diffusion has been repoed to more occurately predict mec A gene presence than oxacillin disc diffusion.The use of cefoxitin MIC test has not been recommended by the CLSI-AST Clinical and Laboratory Standards Institute, but its presence is equivalent to cefoxitin disc diffusion.
