FEMS Microbiol Lett
. 2014 Mar;
353(2):151-6.
PMID: 24606170
Enterococcus faecium, a major cause of nosocomial infections, is often isolated from conditions where biofilm is considered to be important in the establishment of infections. We investigated biofilm formation among...

PLoS One
. 2013 Jul;
8(7):e68813.
PMID: 23874774
The endocarditis and biofilm-associated pilus (Ebp) operon is a component of the core genome of Enterococcus faecalis that has been shown to be important for biofilm formation, adherence to host...

FEMS Microbiol Lett
. 2013 Apr;
344(1):18-24.
PMID: 23551253
Expression of adhesin to collagen of Enterococcus faecalis (ace), a known virulence factor, is increased by environmental signals such as the presence of serum, high temperature, and bile salts. Currently,...

Infect Immun
. 2011 Apr;
79(7):2901-10.
PMID: 21505082
Previous studies have demonstrated that the ebp operon and the ace gene of Enterococcus faecalis, encoding endocarditis- and biofilm-associated pili and an adhesin to collagen of E. faecalis, respectively, are...

PMID: 21502588
Ebp are endocarditis- and biofilm-associated pili of Enterococcus faecalis that are also important in experimental urinary tract infections (UTIs). Our analyses, using available genomes, found that the ebp locus is...
