    Stable inhibition of Gram-positive ESKAPE pathogens by EVQ-218. Growth kinetics of Staphylococcus aureus and <t>Enterococcus</t> <t>faecium</t> were monitored across a concentration gradient of EVQ-218 (0.195–12.5 μg mL −1 ) at passage zero (P0) and passage twenty (P20). ( a , b ) S. aureus and ( c , d ) E. faecium . Across all concentrations, EVQ-218 produced a concentration-dependent inhibition of bacterial proliferation, characterized by delayed onset of exponential growth and reduced maximum optical densities relative to untreated controls. At P0, S. aureus exhibited complete inhibition at 6.25 μg mL −1 and partial suppression at 1.56–3.13 μg mL −1 , whereas E. faecium showed full inhibition at 12.5 μg mL −1 .

    Enterococcus faecium . Prominent intracellular accumulation of EVQ-218 is observed, with multiple electron-dense regions distributed throughout the cytoplasm (yellow arrows). As with other species examined, cell envelope architecture remains intact, consistent with a non-lytic antimicrobial mechanism.
