Agar and agarose used for Staphylococcus aureus biofilm cultivation impact fluoroquinolone tolerance.

Aims: Staphylococcus aureus is an opportunistic pathogen whose treatment is further complicated by its ability to form biofilms. In this study, we examine the impact of growing S. aureus biofilms on different polymerizing surfaces, specifically agar and agarose, on the pathogen's tolerance to fluoroquinolones.
