Scanning electron micrographs of a P. acnes strain ATCC biofilm on a biofilm-coated 0.25-mm-diameter stainless steel insect pin, incubated with P. acnes for 2 days anaerobically at 37°C under static conditions (magnifications, ×371 [A], ×352 [B], and ×33,800 [C]; beam accelerating voltage, 1 kV; working distance, 5 mm) (Zeiss Supra 55VP field emission scanning electron microscope).
