Definition of Enterococcus

Enterococcus: Bacteria normally found in the feces. Two types, Enterococcus fecalis and Enterococcus fecium, cause human disease, most commonly in the form of urinary tract and wound infections. Other infections, including those of the blood stream (bacteremia), heart valves (endocarditis), and the brain (meningitis) can occur in severely ill patients in hospitals. Enterococci also often colonize open wounds and skin ulcers, and are among the most common antibiotic-resistant bacteria.
