  1. MRCNS, methicillin-resistant coagulase-negative staphylococci (strain resistant to all beta-lactam antibiotics: penicillins, penicillins with B-lactamase inhibitor, cephalosporins and carbapenems)
  2. MRSA, methicillin-resistant Staphylococcus aureus (resistant to all beta-lactam antibiotics: penicillins with inhibitors, cephalosporins, monobactams, carbapenems, except for ceftaroline)
  3. ESBL, train with Extended Spectrum Beta-Lactamase
