is enterococcus faecalis bile resistant
There are the two types of vancomycin resistance in enterococci. The first type is intrinsic resistance. Isolates of Enterococcus gallinarum and E. casseliflavus/E. flavescens demonstrate an inherent, low-level resistance to vancomycin.The second type of vancomycin resistance in enterococci is acquired resistance.nterococci can become resistant to vancomycin by acquisition of genetic information from another organism. Most commonly, this resistance is seen in E. faecium and E. faecalis, but also has been recognized in E. raffinosus, E. avium, E. durans, and several other enterococcal species.
