Minimal inhibitory concentrations (MICs) against A. urinae isolates performed by gradient diffusion test and broth microdilution method (BMD). a Benzylpenicillin MICs by gradient diffusion. b Benzylpenicillin MICs by BMD. c Cefuroxime MICs by gradient diffusion. d Cefuroxime MICs by BMD. e Ceftriaxone MICs by gradient diffusion. f Ceftriaxone MICs by BMD. For penicillin, EUCAST breakpoints for Aerococci were used to interpret the results. For cefuroxime and ceftriaxone, EUCAST PK-PD breakpoints were used. S, susceptible; I, susceptible; increased exposure; R, resistant; PK-PD, pharmacokinetic-pharmacodynamic
