<prompt> All of the following are true about Methicillin resistance in MRSA, except-Resistance is produced as a result of altered PBPsResistance may be produced by hyperproduction of beta lactamaseResistance is primarily mediatedtransmitted plasmidsResistance may be missed at incubation temperature of 370C during susceptibility testing  <response>: Resistance in MRSA is chromosomally mediated not plasmid mediated. Resistance is produced as a result of altered PBPs- mediated chromosomal mec A gene which codes for altered PBP- 2A. Resistance may be produced by hyperproduction of beta-lactamase Methicillin resistance is expressed more at 30degC than at 37degC. Therefore, resistance may be missed at incubation temperature at 37degC during susceptibility testing.
