+  "overview": "Enterococcus is a genus of Gram-positive cocci known for their intrinsic ruggedness and antimicrobial resistance. They are part of normal human gastrointestinal flora but are major opportunistic pathogens in healthcare settings. Enterococci are associated with urinary tract infections, bacteremia, endocarditis, intra-abdominal infections, and wound infections. The most clinically important species are Enterococcus faecalis, Enterococcus faecium, and Enterococcus gallinarum.",

+  "ecology": "Enterococci are normal commensals of the human gastrointestinal tract, oral cavity, female genital tract, and are also widespread in animals, soil, water, and food products.",
+  "pathogenicity": "Enterococci cause UTIs, bacteremia, endocarditis, peritonitis, surgical site infections, and device-associated infections. E. faecium is notable for multidrug resistance, including vancomycin-resistant enterococci (VRE) strains. E. gallinarum and E. casseliflavus carry intrinsic VanC, resulting in low-level vancomycin resistance.",
