Effect of conventional irrigation and photoactivated disinfection on Enterococcus faecalis in root canals: An in vitro study

Conclusions: NaOCl alone was not effective in eliminatingE. faecalis completely from the root canals. PAD compared to conventional irrigation showed the best results in removingE. faecalis from root canals.Balakrishna N, Moogi P, Kumar G V, Prashanth B R, Shetty NK, Rao KR.

Alharbi, Shine Kadaikunnan, Mohammed N. Al-anbr, Jamal M. Khaled, Giovanni Benelli The successful treatment of multi-drug resistant microbial pathogens represents a major challenge for public health management. Here, chitosan-alginate (CS/ALG) microspheres with narrow size distribution were fabricated by ionically cross linking method using Ca2+ ions as agents for polymer solidification. The physicochemical properti...

Their chemical structures were confirmed using spectroscopic tools including 1H NMR, 13C NMR and CHN-elemental analyses. Anti inflammatory activity for all target compounds was evaluated in-vitro. The synthesized compounds hinder the biofilm formation and control the growth of the pathogen, Staphylococcus epidermis. Anti microbial activity of the compound...

Publication date: Available online 11 December 2017 Source:Microbial Pathogenesis Author(s): Wei Fan, Zhuo Huang, Bing Fan Static magnetic field (SMF) has been shown to biologically affect various microorganisms, but its effects on Enterococcus faecalis, which is associated with multiple dental infections, have not been reported yet. Besides, Enterococcus faecalis was found to be resistant to the alkaline environment provided by a major dental antimicrobial, calcium hydroxide. Therefore, the antibacterial activity of prolonged exposure to moderate SMF (170 mT) and its possible synergistic activity with alkaline pH (p...

Conclusion Spread of predominantly detected vancomycin-resistant E. faecium was limited to the department level with no evidence for wider dissemination within the hospital. Well standardized and validated (semi-)automated repPCR systems are useful for rapid detection of possible VRE transmission. However, suspected transmissions need to be confirmed by clinical and microbiological parameters.

Conclusions This article describes the first UK outbreak with a single strain of linezolid- and glycopeptide-resistant E. faecium harbouring the cfr gene, affecting five patients in a nephrology unit. Following the implementation of aggressive infection control measures, no further cases were detected beyond a two-week period.

Conclusion: The experiments revealed that L. plantarum 15HN, L. lactis subsp. cremoris 44L and E. mundtii 50H strains, which were isolated from shiraz, cheese and shiraz, respectively, displayed a desirable tolerance to low pH and high bile salts, favorable anti-pathogen activity, and acceptable antibiotic susceptibility; hence, they could be considered as novel probiotic candidates and applied in the food industry.

ri PM Abstract The aim of this study was the evaluation of antibacterial and antioxidant properties of Monofloral Etna Castanea sativa Miller honeys. Escherichia coli ATCC 25,922, Pseudomonas aeruginosa ATCC 27,853, Enterococcus faecalis ATCC 29,211 and Staphylococcus aureus ATCC 29,213 were investigated for their susceptibilities to two different honeys. Antioxidant activity was evaluated by ORAC, NO scavenger assays, FRAP and DPPH. Antioxidant activity and antibacterial properties were compared with chestnut honeys from different geographical areas and with Manuka honey. UPLC-MS/MS was used for major components ...
