**10. Conclusion**

Enterococci that were once part of the genus Streptococci, moved out to form a new genus and the genus expanded to include species present in a wide variety of animals. With the advent of Cephalosporins, they gained access to hospitals and now are acquiring new resistance genes at a rapid pace. *E. faecalis* and *E. faecium* are the major pathogens, however *E. casseliflavus* and *E. gallinarum* are also coming up in greater numbers. Spread is mainly by contact transmission and Vancomycin resistant (VRE) isolates are a constant threat in the nosocomial setting.
