In vitro antimicrobial activities of Ga(NO₃)₃. Activity of Ga(NO₃)₃, 0.5–512 μM, against planktonic bacteria (a) and biofilms (b) of Staphylococcus epidermidis ATCC 12228 and Staphylococcus aureus ATCC 29213 following overnight exposure to increasing concentrations, in MHB II (0.3 g/L) broth in 96-well plates. Data is representative of mean ± SD of three independent experiments. Statistical analysis was performed using Student’s -test; indicates relative to the untreated control group; Student’s -test.
