BBL CHROMagar VanRE (CVRE) was compared with bile esculin azide agar plus vancomycin to screen for vancomycin-resistant enterococcus (VRE) colonization. CVRE distinguishes Enterococcus faecalis (green colonies) from Enterococcus faecium (mauve colonies) on the basis of chromogenic substrate use. CVRE sensitivity and specificity were 98.6% and 99.1%. Positive and negative predictive values were ...

conclusions the simultaneous detection of e. faecalis in a patient’s gastrointestinal and urine tracts can indicate the presence of uropathogenic enterococcus. further study is essential to identify virulence factors involved in the colonization of these isolates in the urinary tract. background urinary tract infection (uti) is one of the most common bacterial infections in outpatient settings....

background and objectives:increased antibiotic resistance as a result of using antimicrobial drugs and also their various adverse effects has caused that in recent years, investigation of medicinal plants beconsidered for discovering new medicinal resources against bacterial infections. this study was performed with the objective of determining the antimicrobial activity of aqueous and ethanoli...

results although the antibacterial effect of 16 ppm aqueous ozone using a manual technique had an insufficient effect, its ultrasonic application technique resulted in complete disinfection in the root canals. conclusions the bactericidal activity of high concentration of aqueous ozone combined with ultrasonic application technique showed efficacy similar to that of 5.25% naocl in root canals. ...

conclusions anova results showed that the effect of cycle and time on the selected bacterial removal efficiency were more important than that of the microbial concentration. results the results showed that e. coli and e. faecalis were effectively treated at 10 pulse/s in 9 minutes and 6 log cfu/ml bacterial suspension (p < 0.0001 for e. coli with 99.99% (4 log) and p = 0.0002 for e. faecalis wi...

introduction: infecting microorganisms of the root canals are difficult to eliminate during endodontic treatment. in this study the effect of root canal disinfection with photodynamic therapy (pdt) at different time intervals in comparison to 2.5% sodium hypochlorite (naocl) irrigation and passive ultrasonic irrigation (pui) in extracted teeth colonized with enterococcus faecalis and candida al...

objectives we investigated the potential relationships between biofilm formation and prevalence of virulence genes (asa1, esp, cyla, and gele/spre), and antimicrobial resistance genes (aac (6’)/aph (2”) in enterococcus faecalis isolated from patients with urinary tract infection. patients and methods in this survey 95 e. faecalis isolates from patients with urinary tract infections staying at s...

introduction: this in vitro study compared the antibacterial efficacy of 2.5% sodium hypochlorite gel and 2.5% and 5.25% sodium hypochlorite solutions on enterococcus faecalis ( e. faecalis ) biofilm. methods and materials: the root canals of 60 extracted human single-rooted teeth were contaminated with e. faecalis and incubated for 6 weeks. the samples were randomly assigned to three experimen...

introduction: root canal treatment is based on elimination of intraradicular microorganisms. calcium hydroxide ca(oh) 2 is the most widely used material for canal dressing, however, enterococcus faecalis has been reported to be resistant bacteria in persistent apical periodontitis . the purpose of this study was to evaluate the efficacy of ca(oh) 2 on the elimination of intraluminal and intratu...

introduction: enterococcus faecalis ( e. faecalis ) has the ability to invade the dentinal tubules and resist high ph levels. as a result, calcium hydroxide (ch) is not much effective on this bacterium. in theory, nanoparticle calcium hydroxide (nch) has smaller size and high surface area that enables it to penetrate into the deeper layers of dentin and be more effective on e. faecalis. this in...
