patients and methods one hundred thirty-eight clinical specimens collected from different wards of imam reza hospital were identified to the species level by biochemical tests. antimicrobial susceptibility tests against kanamycin, teicoplanin, streptomycin, imipenem, ciprofloxacin, and ampicillin were performed by the disk diffusion method. the minimum inhibitory concentrations of gentamicin, s...
Combinations of either brodimoprim or trimethoprim plus either carbenicillin, gentamicin, ciprofloxacin or rifampicin showed synergy at sub-inhibitory concentrations against both Enterococcus faecalis NCTC 5957 and 775. Brodimoprim alone and in combination showed greater antibacterial activity against both strains of E. faecalis than trimethoprim. MBCs of brodimoprim and trimethoprim were 14.4 ...
Enterococcus faecalis is increasingly becoming an important nosocomial infection opportunistic pathogen. E. faecalis can easily obtain drug resistance, making it difficult to be controlled in clinical settings. Using bacteriophage as an alternative treatment to drug-resistant bacteria has been revitalized recently, especially for fighting drug-resistant bacteria. In this research, an E. faecali...
i ntroduction: calcium hydroxide (ch) is one of the most common intracanal medications. corticosteroids (cs) are used in endodontics because of their anti-inflammatory activity. this study aimed to evaluate the antimicrobial effect of ch+betamethasone and ch+saline against enterococcus faecalis ( e. faecalis ) using agar diffusion test and measuring the microbial zone of inhibition (zoi). metho...
background: the aim of this study was to evaluate and compare the in vitro biofi lm forming capacity of enterococcus faecalis on gutta-percha points disinfected with four disinfectants. materials and methods: a total of 50 gutta-percha points used in this study were divided into four test groups based on disinfectant (5.25% sodium hypochlorite, 2% chlorhexidine gluconate, 20% neem, 13% benzalko...
Xenorhabdus nematophila engages in a mutualistic association with the nematode Steinernema carpocapsae. The nematode invades and traverses the gut of susceptible insects. X. nematophila is released in the insect blood (hemolymph), where it suppresses host immune responses and functions as a pathogen. X. nematophila produces diverse antimicrobials in laboratory cultures. The natural competitors ...
This aim of this study was to assess the ability of manual or rotary instrumentation associated with photodynamic therapy (PDT) to reduce Enterococcus faecalis using three combinations of light/photosensitizers: toluidine blue O/laser, fuchsin/halogen light and fuchsin/LED. Twenty deciduous molars were selected and contaminated with Enterococcus faecalis (McFarland 0.5 scale). Working length de...
Introduction: This interventional in-vitro study aimed to evaluate the antimicrobial activity of a new Nano Zinc OxideEugenol (NZOE) sealer in comparison with AH26 and Pulpdent common root canal sealers against endodontic pathogens. Methods: The antimicrobial efficacy of three sealers(NZOE, AH26 and Pulpdent) against Enterococcus faecalis (ATCC 29212), Escherichia coli (ATCC 25922), Streptococ...
According to the current edition of the Bergey's Manual of Systematic Bacteriology [11] the tyrosine decarboxylation test allows the differentiation of enterococci. Tyrosine is decarboxylated to the biogenic amine tyramine by E. faecalis and not by E. faecium strains. In the present study we sequenced the16S rDNA of two tyramine-producing strains, BIFI-56 and BIFI-58, presumptively classified a...
Enterococci are common cause of hospital acquired infection and have become progressively more resistant to antibiotic. Among the 13 Enterococcus species ninety percentage of Enterococcal infection are due to Enterococcus faecalis .E. faecalis is a causative agent for nosocomial infection. The present study was carried out to asses the changing trends in antibiotic susceptibility of Enterococcu...
