CLPP and endocarditis: Eleven of these genes (ace, bopD, ebpA, ebpB, ebpC, srtC; clpP; cpsA, cpsB; efaA; fss1) coding for biofilm-associated proteins, caseinolytic protease, capsular polysaccharide biosynthesis, endocarditis specific antigen and fibrinogen adhesins were found in all E. faecalis, whereas hylA, gelE, and sprE coding for hyaluronidases, biofilm-associated proteins and serine protease respectively, were present in >86% of all isolates from this species.
