Schematic representation of the results of immunofluorescence and a confocal laser scanning microscope; Samples of ARSE after treatment for 4 h with Amoxicillin, Quercetin, either alone or in combination. Con = control (drugs free); Amx (8) = 8 μg/mL Amoxicillin; Que (128) = 128 μg/mL Quercetin; Amx (3) + Que (48) = 3 μg/mL Amoxicillin plus 48 μg/mL Quercetin. The cells were stained for DNA with DAPI (blue) and labelled for peptidoglycan (PGC) (green) using respective antibodies. DNA in all groups was localized in the central of the cell and surrounded by a peptidoglycan layer (merged images). Scale bar = 1 μm
