Background: Bacteremia due to Enterococcus faecalis is usually caused by strains resistant to most antibiotics. Effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. The aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococc...

Aim: To isolate and identify in a Chilean population, Enterococcus spp. from root canals with persistent chronic apical periodontitis (CAP) and to investigate the potential correlation between the bacteria and the observed clinical features. Methods: Twenty patients with indication for endodontic retreatment due to persistent CAP were selected. Data from patient general health and dental clinic...

background and aims. the aim of this study was to evaluate the antibacterial activity of one-step self-etch adhesives on enterococcus faecalis on days 1, 7 and 14 with the use of modified direct contact test. materials and methods. the modified direct contact test was used to evaluate the antibacterial effect of adper easy one, bond force, clearfil s3 bond, futurabond m, g-bond, ibond and optib...

Little is known on the genetic relatedness and potential dissemination of particular enterococcal clones in Malaysia. We studied the antibiotic susceptibility profiles of Enterococcus faecium and Enterococcus faecalis and subjected them to pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). E. faecium and E. faecalis displayed 27 and 30 pulsotypes, respectively, and 1...

three experiments were carried out for isolation of bacteriophage against growth reducing enterococcus faecalis and evaluation of its efficacy to control enterococci colonization in intestine of japanese quails. in experiment one, 60 enterococci spp were isolated from gastrointestinal contents of adult quails, which among them seven isolates were selected based on preliminary tests. in experime...

introduction: this in vitro study aimed to assess the effectiveness of a single-file rotary system (oneshape) in reduction of intracanal bacteria. methods and materials: eighty one single-rooted mandibular first premolars with single canals were used. six samples were selected as aseptic control group. seventy five remaining specimens were infected by enterococcus faecalis and incubated for 72 ...

i ntroduction: due to the complex anatomy of the root canal system and high surface tension of common root canal irrigants (rci), conducting an investigation on rcis containing surfactants is a priority. the aim of this in vitro study was to verify the antibacterial potential of rci with low surface tension in root canals infected with enterococcus faecalis ( e. faecalis ). methods and material...

introduction: enterococcus (e) faecalis bacteria adhere to dentine of teeth root canals to form the biofilm. e. faecalis has been shown to be resistant to antibiotics. this in vitro study aimed to investigate the efficacy of vancomycin and doxycycline in inhibiting e. faecalis biofilm formation. materials and methods: a total of 60 extracted human teeth were incubated with e. faecalis (atcc 355...

introduction: bacteria are the primary etiology of pulpal and periradicular pathosis. in endodontically treated teeth with persistent infections only one or a few bacterial species are present of which the most important is enterococcus faecalis. the aim of this study was to compare antibacterial efficacy of canal disinfectants including 5.25% sodium hypochlorite, 2% chlorhexidine, mtad (a mixt...

Large amounts of tylosin, zinc-bacitracin, and avilamycin are currently used as prophylactics in New Zealand broiler production. Avoparcin was also used from 1977 to 2000. A total of 382 enterococci were isolated from 213 fecal samples (147 individual poultry farms) using enrichment broths plated on m-Enterococcus agar lacking antimicrobials. These isolates were then examined to determine the p...
