Under a magnification of 1817X, this scanning electron microscopic (SEM) image depicted numbers of Staphylococcus aureus bacteria, which were found on the luminal surface of an indwelling catheter. A red blood cell (RBD), also known as an erythrocyte, was also present, with its biconcave cytomorphology. Of importance is the sticky-looking substance woven between the round cocci bacteria, which was composed of polysaccharides, and is known as biofilm. This biofilm has been found to protect the bacteria that secrete the substance from attacks by antimicrobial agents such as antibiotics.
