*2.3. Microorganisms and Culture*

Two strains of *Salmonella enteritidis* (drug-resistant *S. enteritidis* SJTUF 10987 and the standard strain *S. enteritidis* ATCC 13076) and 12 strains of *Staphylococcus aureus*, including 11 drug-resistant strains *S. aureus* SJTUF 20745, *S. aureus* SJTUF 20746, *S. aureus* SJTUF 20755, *S. aureus* SJTUF 20758, *S. aureus* SJTUF 20772, *S. aureus* SJTUF 20827, *S. aureus* SJTUF 20841, *S. aureus* SJTUF 20862, *S. aureus* SJTUF 20973, *S. aureus* SJTUF 20978, and *S. aureus* SJTUF 20991, as well as the standard strain *S. aureus* ATCC 25923 were used in this study. These strains were stored at −80 ◦C. To prepare the inocula, a single colony of the bacteria grown on the LB agar plate was selected and transferred into the LB broth to culture overnight in a rotary incubator (37 ◦C, 150 rpm). The bacterial suspension was then diluted to approximately 1 <sup>×</sup> 106 colony-forming units (CFU)/mL for subsequent antibacterial experiments.
