Introduction: Root treatment will not be successful, without a proper root canal irrigation with less disadvantages and antibacterial effect. The aim of this study was to compare antimicrobial effect of cedar extract and 2.5%NaOCl on E. faecalis. Materials & Methods: In disk diffusion test, a standard suspension of E. faecalis (ATCC 29212) was cultured on plate and different concentrations (0....
Dried, fresh and glycolic extracts of Zingiber officinale were obtained to evaluate the action against G. mellonella survival assay against Enterococcus faecalis infection. Eighty larvae were divided into: 1) E. faecalis suspension (control); 2) E. faecalis + fresh extract of Z. officinale (FEO); 3) E. faecalis + dried extract of Z. officinale (DEO); 4) E. faecalis + glycolic extract of Z. offi...
AIM The hypotheses tested in this study were that: (i) Enterococcus faecalis can survive long-term entombment in root filled teeth without additional nutrients, (ii) initial cell density influences the survival of E. faecalis in instrumented root canals and (iii) gelatinase-production capacity influences the survival of E. faecalis in root canals. METHODOLOGY The root canals of 150 extracted ...
There is no information on investigations comparing phenotypic and genotypic differences in MDR and MDS E. faecalis strains in literature. The study included 70 clinical E. faecalis isolates from human origin. None of the isolates tested demonstrated any in vitro sensitive to vancomycin, with MIC values of all the strains for vancomycin of ≥23 μg/mL. High-level resistances to ampicillin and str...
The present study was done to scrutinize the possible relation between infective genes and antimicrobial resistance in Enterococcus faecalis and Enterococcus faecium. Considering the fact that the presence of recognized infective determinants among clinical isolates may promote the emergence of infections and persistence of Enterococci in hospital settings, which can lead to an increase in anti...
Sixteen isolates of Enterococcus faecalis were recovered from retail poultry samples (seven chickens and nine turkeys) purchased from grocery stores in the greater Washington, D.C., area. PCR for known streptogramin resistance genes identified vat(E) in five E. faecalis isolates (three isolates from chickens and two isolates from turkeys). The vat(E) gene was transmissible on a ca. 70-kb plasmi...
introduction: the purpose of this study was to compare the antimicrobial efficacy of sodium hypochlorite (sh) and calcium hypochlorite (ch) against enterococcus faecalis (e. faecalis) using quantitative real-time polymerase chain reaction (qpcr) analysis and also to compare their cytocompatibility on l929 murine fibroblasts using mossman’s tetrazolium toxicity (mtt) assay. methods and materials...
A 22-kb segment of chromosomal DNA from Enterococcus faecalis OG1RF containing the pyrimidine biosynthesis genes pyrC and pyrD was previously detected as complementing Escherichia coli pyrC and pyrD mutations. In the present study, it was found that the E. faecalis pyrimidine biosynthetic genes in this clone (designated pKV48) are part of a larger cluster resembling that seen in Bacillus spp. T...
Meat and particularly ground beef is frequently associated with Food Poisoning episodes and breeches in Food Safety. The main goal of this research was to evaluate the bactericide effect of the probiotic Enterococcus faecalis CECT7121, against different pathogens as: Escherichia coli O157:H7, Staphylococcus aureus, Clostridium perfringens and Listeria monocytogenes, inoculated in ground beef me...
BACKGROUND High-level aminoglycoside resistance (HLAR) that precludes bactericidal synergism with penicillins or glycopeptides and nephrotoxicity related to aminoglycoside treatment are major problems in treating Enterococcus faecalis endocarditis. OBJECTIVE To evaluate the efficacy and safety of ampicillin plus ceftriaxone for treating endocarditis due to E. faecalis with and without HLAR. ...
