Enterococcus faecalis OG1RF Evolution at Low pH Selects Fusidate-Sensitive Mutants in Elongation Factor G and at High pH Selects Defects in Phosphate Transport
Appl Environ Microbiol. 2023 Jun 5:e0046623. doi: 10.1128/aem.00466-23. Online ahead of print.ABSTRACTEnterococcus bacteria inhabit human and soil environments that show a wide range of pH values. Strains include commensals as well as antibiotic-resistant pathogens. We investigated the adaptation to pH stress in E. faecalis OG1RF by conducting experimental evolution under acidic (pH 4.8), neutral pH (pH 7.0), and basic (pH 9.0) conditions. A serial planktonic culture was performed for 500 generations and in a high-pH biofilm culture for 4 serial bead transfers. Nearly all of the mutations led to nonsynonomous codons, indic...

Evaluation of Antibacterial Efficacy of Two Commercially Available Probiotics as Intracanal Medicament against < em > Enterococcus faecalis < /em > : An < em > In Vitro < /em > Study
CONCLUSION: Commercially available probiotics can be used effectively as an intracanal medicament to fight against E. faecalis, Poloxamer 407 is a promising vehicle for delivering probiotics inside the root canal system. Further in vitro and in vivo studies are needed to determine the full potential of "Bacteriotherapy" with an application of probiotics.CLINICAL SIGNIFICANCE: If probiotics are proved to be an effective intracanal medicament against E.faecalis they can be used as an alternative to calcium hydroxide as intracanal medicament with no side effects to the host.PMID:37272126 | DOI:10.5005/jp-journals-10024-3466

Antimicrobial Efficacy of Silver Diamine Fluoride against < em > Enterococcus faecalis < /em > : A Systematic Review of < em > In Vitro < /em > Studies
Conclusions. Within the limitations of the systematic review and the studies reviewed, SDF may be effective against E. faecalis and therefore could be used as an intracanal medicament and/or irrigant to prevent reinfections of the root canals and improve the outcomes of endodontic treatment. However, animal and clinical studies should be carried out to determine the efficacy of SDF in endodontics. Trial Registration. The protocol for this review was registered on PROSPERO. Registration number: CRD42021224741.PMID:36567909 | PMC:PMC9788898 | DOI:10.1155/2022/6544292

Detoxification of LTA by intracanal medication: analysis by macrophages proinflammatory cytokines production
Braz Dent J. 2022 Nov-Dec;33(6):36-43. doi: 10.1590/0103-6440202205195.ABSTRACTThe aim of this study was to evaluate in vitro the effect of calcium hydroxide [Ca(OH)2], 2% chlorhexidine gel (CHX) on macrophages (RAW 264.7) to produce pro-inflammatory cytokines and nitric oxide after pretreatment with lipoteichoic acid (LTA) of Enterococcus faecalis. Forty-eight human single-rooted teeth were instrumented with R25.08 (RECIPROC) and sterilized by gamma irradiation. LTA was inoculated in the root canal of each specimen for 96 hours. Specimens were instrumented with 40.06 and 50.05 (RECIPROC) and medicated with: I) Pyrogen-fre...
