A Drugs tested (with antimicrobial class and drug displayed on the y axis) and microbiological susceptibility results for Escherichia coli, Enterococcus faecium and Enterococcus faecalis are shown in green color on the x axis. *Indicates antimicrobial class used to determine multidrug resistant status defined as resistance to ≥ 1 agent in ≥ 3 antimicrobial categories per Magiorakos et al. [27]. Amoxi/Clav Amoxicillin/clavulanate; Pip/Tazo Piperacillin/Tazobactam; TMS trimethoprim/sulfamethoxazole. B ABRx Panel results (Diatherix-Eurofins, Hunstville, AL): 17 antimicrobial resistance genes and corresponding drugs (shown in blue) to which bacteria would show resistance if gene is present
