INTRODUCTION The aim of this study was to investigate the prevalence, phenotype, and genotype of Enterococcus faecalis isolated from saliva and root canals in patients with endodontic treatment failure. METHODS Samples were collected from 32 adults undergoing retreatment for periapical lesions after endodontic treatment performed at least 2 years previously. Isolates that were presumed to be ...
Enterococcus faecalis is part of the commensal microbiota of humans and its main habitat is the gastrointestinal tract. Although harmless in healthy individuals, E. faecalis has emerged as a major cause of nosocomial infections. In order to better understand the transformation of a harmless commensal into a life-threatening pathogen, we developed a Recombination-based In VivoExpression Technolo...
UNLABELLED Enterococcus faecalis is a Gram-positive bacterium that natively colonizes the human gastrointestinal tract and opportunistically causes life-threatening infections. Multidrug-resistant (MDR) E. faecalis strains have emerged, reducing treatment options for these infections. MDR E. faecalis strains have large genomes containing mobile genetic elements (MGEs) that harbor genes for anti...
Background: Prostate cancer is the most commonly diagnosed malignancy and the second leading cause of cancer deaths among men in the world. Immunotherapy is a new, non-invasive and effective method for the treatment of cancer, but its side effects on the normal flora of bacteria and opportunistic infections not known yet. The aim of this study was to evaluate the effects of immunotherapy on Ent...
MRL-1237, [1-(4-fluorophenyl)-2-(4-imino-1,4-dihydropyridin-1-yl) methylbenzimidazole hydrochloride], is a potent and selective inhibitor of the replication of enteroviruses. To reveal the target molecule of MRL-1237 in viral replication, we selected spontaneous MRL-1237-resistant poliovirus mutants. Of 15 MRL-1237-resistant mutants obtained, 14 were cross-resistant to guanidine hydrochloride (...
The prevalence of Enterococcus faecalis was investigated in diseased swine in Hunan Province, China between February 2007 and February 2011. A total of 385 diseased swine dissected in prosectorium from 10 representative administrative regions in Hunan Province were examined for the presence of E. faecalis. Forty-two out of 385 (10.91%) diseased swine were found to be infected with E. faecalis b...
Enterococcus faecalis is an opportunistic pathogen that causes serious infections in humans and animals and is also an important bacterium for dairy and probiotic supplement production. Therefore, bacteriophages infecting E. faecalis may be useful for phage therapy against multidrug-resistant strains or may threaten industrial fermentation. We isolated a virulent Siphoviridae bacteriophage, BC-...
Enterococcus faecalis is an important agent of endocarditis and urinary tract infections, which occur frequently in hospitals. Antimicrobial therapy is complicated by the emergence of drug-resistant strains, which contribute significantly to mortality associated with E. faecalis infection. In this issue of the JCI, Nallapareddy and colleagues report that E. faecalis produces pili on its surface...
On the basis of pIP501, a green fluorescent protein (GFP)-tagged monitoring tool was constructed for quantifying plasmid mobilization among Gram-positive bacteria and between Gram-positive Enterococcus faecalis and Gram-negative Escherichia coli. Furthermore, retromobilization of the GFP-tagged monitoring tool was shown from E. faecalis OG1X into the clinical isolate E. faecalis T9.
Enterococcus faecalis is becoming an increasingly important opportunistic pathogen worldwide, especially because it can cause life-threatening nosocomial infections. Treating E. faecalis infections has become increasingly difficult because of the prevalence of multidrug-resistant E. faecalis strains. Because bacteriophages show specificity for their bacterial hosts, there has been a growth in i...
