Confocal microscopy images of biofilms. Representative images of biofilms developed on polystyrene pegs following 24 h incubation at 37 °C. Staphylococcus aureus isolates are classified into three groups (weak, moderate and high) according to their biofilm-forming ability. Upper panels show the X-Y planes (top view), while the lower panels show the Z section (side view).
