Surface properties of materials influence bacterial adhesion and play important roles in biofilm antibiotic resistance. The two-component system CroRS of Enterococcus faecalis (E. faecalis) can be act...
The aim of our study was to characterize the epidemiological situation concerning nosocomial vancomycin-resistant Enterococcus faecalis of VanA-phenotype (VREfs-VanA) in Poland by investigating their ...
To compare the antimicrobial effect of bioceramic endodontic cements with and without silver nanoparticles on Enterococcus faecalis....
Six groups were evaluated (n=8), and divided according to the materials: MTA Flow + AgNP ; MTA Flow Group; Bio C Repair + AgNP; Bio C Repair; PBS Cimmo + AgNP; PBS Cimmo. The groups were maintained fo...
The addition of silver nanoparticles resulted in a statistically significant difference for MTA and CIMMO PBS cements (p⟨0.05), with the lowest bacterial growth being shown by the MTA group. For all g...
The addition of silver nanoparticles to bioceramic cements was efficient to promote an acceleration of bacterial death....
The ability of bacteria to adapt to the external environment is fundamental for their survival. A halotolerant microorganism Enterococcus faecalis able to grow under high salt stress conditions was is...
Enterococcus faecalis is a commensal bacterium commonly found in the human gastrointestinal tract. However, in individuals with compromised immune systems, the pathogen can lead to severe illness. Thi...
In all patients with cardiac implantable electronic devices (CIED) and Enterococcus faecalis bacteremia (EfsB), endocarditis (IE) and CIED infection should be suspected. Guidelines recommend extractio...
A population-based cohort of patients with monomicrobial EfsB from January 2014 to November 2020 was identified through microbiology registers in the Region Skåne, Sweden. Data on CIED and other clini...
Among 1087 episodes of EfsB, 72 patients with CIED and monomicrobial EfsB were identified. Five of these patients were diagnosed with IE (7%), three of whom had echocardiographic changes on the CIED. ...
In patient with monomicrobial EfsB, it seems safe to omit extraction if no structural changes are found on the CIED....
Spectra™ VRE agar (Remel, Lenexa, KS) is a chromogenic agar that is FDA approved for screening patients for VRE colonization. The package insert recommends confirming isolates with identification and ...
Our laboratory sought to develop a workflow to optimize the use of the medium....
We plated 3,815 rectal swabs to the Spectra VRE agar and compared results to traditional identification and susceptibility testing....
Dark blue or purple colonies on the agar demonstrated a sensitivity of 98% and specificity of 85% for detection of VRE faecium, but light blue colonies were significantly less specific for E. faecalis...
We streamlined our workflow to accept dark blue or purple colonies as VRE faecium and plan to perform additional testing only on light blue colonies. Interestingly, higher quantity of growth increased...
Enterococcus faecalis (E. faecalis) is one of the major microorganisms that causes failure of endodontic treatment. This study aimed to investigate the antibacterial activity of apigenin and its syner...
The antibacterial activities were characterized by viability analysis including colony forming units and confocal laser scanning microscopy (CLSM) analyses. The effect on biofilm biomass was measured ...
The viability of E. faecalis in biofilms decreased by apigenin treatment in a dose-dependent manner. While apigenin alone did not significantly affect the biofilm biomass, apigenin + RGO reduced the b...
The results suggested that the combined use of apigenin and RGO could be a potential strategy for effective endodontic disinfection....
Biofilms are involved in serious problems in medical and food sectors due to their contribution to numerous severe chronic infections and foodborne diseases. The high resistance of biofilms to antimic...
Infections caused by the bacteria Enterococcus faecalis (also known as E. faecalis) are common in hospitals. This bacterium is resistant to a wide range of medicines and causes a variety of nosocomial...
