Enterococcus faecium, SEM
Coloured scanning electron micrograph (SEM) of Enterococcus faecium (also known as Streptococcus faecium), Gram-positive, vancomycin resistant (VRE), coccus prokaryote that grows in groups or chains. Shown here is a single cell undergoing bacterial division (fission). E. faecium is commonly found in the guts of humans and other animals. It does not normally cause disease, but can be an opportunistic pathogen when the immune system is impaired. It is an important nosocomial (hospital-acquired) pathogen. E. faecium is known to have a resistance to several types of antibiotics including gentamicin, tetracycline, erythromycin, teicoplanin and penicillin. Magnification: x18,000 when shortest axis printed at 25 millimetres.
