Scanning electron microscopy (SEM) of the biofilm from the external surface of the J stent from female patient. a–d External surface of the J stent. Heap-shaped, patchy bacterial colonies are shown. Most of the bacteria were embedded on the extracellular matrix. a 5000×, b 10,000×, c 12,000×, and d 12,000× magnification, respectively. Arrows show rod-shaped bacteria. No crystalline material was deposited in the bacterial biofilm
