  1. So where is the evidence that methicillin resistance in MRSA
    means the resistant staph was the result of over-prescription of prior antibiotics ?

  2. What I’m searching for, is, why cannot there be virulent strains of staph., resistant to methicillin not caused by prior antibiotic interference and, whether that contamination cannot come from exogenous sources introduced into hospital settings ?

    I don’t think its that prior antibiotics cause mutations but in the absence of antibiotic there would be no selection for the resistant bacteria to outgrowth the sensitive bacteria.
