In vitro activity of Amazon plant extracts against Enterococcus faecalis
Previous studies analyzing 2,200 plant extracts indicated anti-enterococcal activity in 25 extracts obtained from Brazilian forests' plants. In the present study, these extracts were subjected to microdilution broth assay (MDBA) and disk diffusion assay (DDA) using planktonic Enterococcus faecalis ATCC(®) 29212™ and were submitted to phytochemical analysis in TLC and HPLC. Three extracts obtain...
متن کاملMechanisms of resistance to imipenem and ampicillin in Enterococcus faecalis.
We found ampicillin- and imipenem-resistant isolates of vanA-possessing Enterococcus faecalis with MICs of 8 to 16 microg/ml and 4 to 32 microg/ml, respectively. There have been few reports about penicillin- and imipenem-resistant E. faecalis. Two mechanisms of beta-lactam resistance in E. faecalis, the production of beta-lactamase and the overproduction of penicillin-binding proteins (PBPs), h...
متن کاملAntimicrobial activity of three different endodontic sealers on the enterococcus faecalis and lactobacillus (in vitro)
Introduction: Growth and proliferation of the remaining microorganisms within the root canals may destroy the surrounding tissue of the root and leads to periapical lesion. Consequently, the complete elimination of microorganisms from the root canal is a n important goal of endodontic therapy. Endodontic sealers do not provide complete seal in root canal system, and micro spaces have always rem...
متن کاملAntibiotic Resistance in Enterococcus faecalis Isolated from Hospitalized Patients
BACKGROUND AND AIMS Enterococci are Gram-positive cocci that often occur in pairs (diplococci) or short chains. Be-side developing high level of antibiotic resistance, these bacteria can cause wide range of disease in human, thus to help provide an effective treatment for infections caused by this genus, this study was conceived to provide information on Enterococcus faecalis Antibiotic resista...
متن کاملComparison of the Antibacterial Efficacy of Alexidine and Chlorhexidine Against Enterococcus Faecalis: An in Vitro Study
Introduction Root canal irrigants play an important role in reducing intracanal microorganisms, which in turn helps in achieving a successful outcome for the root canal treatment. Objective To compare the antibacterial efficacy of alexidine and chlorhexidine against Enterococcus faecalis. Methods A total of 50 extracted single-rooted teeth were randomly divided into five groups after being infe...
