Four bacterial isolates displayed amoxicillin resistance with MICs ≥ 100 µg/mL at an OD of 620 nm. The results are presented as the mean ± SEs (n = 4), and the MIC breakpoint for amoxicillin is 8 µg/mL according to EUCST 2022. Isolates IDs are Strain 01, Strain 02, Strain 03, and Strain 04. Graphs were constructed via SigmaPlot V.11.0 [27]
