MBC—minimal bactericidal concentration of agent when tested alone. FBC—fractional bactericidal concentration, i.e., the lowest bactericidal concentration when tested with sub-bactericidal concentration of AgNPs, i.e., 0.25 × MBC (2 µg Ag mL−1). FBC index—fractional bactericidal concentration index.
