Staph aureus now a days are betalactamase producing -- so not responding to pencillin and cephalosporins...

For staphylococcus recommended drugs as said by Condroid Fisher is


Oxacillin,Cloxacillin, Dicloxacillin, Nafcillin,( Ox,Clox,Diclox & Naf).

Ceftriaxone doesnt cover beta lactamase.

Default They arent effective

Third generation cephalosporins are the most inefective of all the kinds vs gram (+) organisms and s.aureus for that matter.

If you read microbiology made ridiculously simple or any other pharm book, they mention that for every increase in generation you lose coverage vs gram (+) organisms.

Second generation or 4th generation cepefime would be a slightly better choice but i wouldnt give that vs s.aureus, id rather give dicloxacilin and all the beta lactamese resistant penicilins or even vancomicin if the strain is MRSA or Linezolid if you have the bad luck of having a VRSA
