  1. * In Sweden and Lithuania, iso-penicillin and oxacillin respectively were used as surrogate antibiotics for methicillin susceptibility. T/S = Trimethoprim-sulfamethoxazole
  2. P/T = Piperacillin- tazobactam. a = All resistant strains were Staphylococcus epidermidis. b = All resistant strains were Staphylococcus epidermidis except one. c = The penicillin-resistant isolate was a Streptococcus pneumoniae
