LuxS affects biofilm maturation and detachment of the periodontopathogenic bacterium Eikenella corrodens

Riemerella anatipestifer lacks luxS, but can uptake exogenous autoinducer-2 to regulate biofilm formation

“…Biofilm formation was enhanced in Eikenella corrodens [26] by the addition of AI-2, while AI-2 inhibited biofilm formation in Candida albicans [27] and Bacillus cereus [28]. In the present study, our results showed that AI-2 inhibited RA biofilm formation.…”

Cobalt-chromium alloys in dentistry: An evaluation of metal ion release

“…32 E. corrodens can play a role in specific coaggregation with certain gram-positive and gramnegative bacteria present in human periodontal pockets but probably cannot produce a stable biofilm without interaction with other microflora components. 31,34,35,37 The final aim of this study was not to reproduce a biofilm comparable with dental plaque but to detect a possible effect of a highly abundant oral prokaryotic species. However, the biological effect investigated in this study could have been reduced by the simplified in vitro model.…”

“…It seems to play a role in biocorrosion processes as reported for others dental alloys. [35][36][37] Co-Cr dental alloys can be prepared with different synthetic processes. The computer-aided design/computer-aided manufacturing technique is based on the milling of frameworks from a preformed block of alloy or by using direct laser metal sintering (LS), where a high-power laser fuses small metal alloy layers to reproduce the desired 3-dimensional object.…”

D-Ribose Interferes with Quorum Sensing to Inhibit Biofilm Formation of Lactobacillus paraplantarum L-ZS9

“…Our data showed that D -ribose could inhibit AI-2 activity of L-ZS9, suggesting that it can be used as a QSI of the LuxS/AI-2 QS system in L-ZS9. LuxS/AI-2 QS regulates biofilm formation of many bacteria such as Streptococcus mitis, Pseudomonas aeruginosa PAO1, Eikenella corrodens, Candida albicans, Riemerella anatipestifer, Aggregatibacter actinomycetemcomitans , and Bifidobacteria ( Shao et al, 2007 ; Karim et al, 2013 ; Bachtiar et al, 2014 ; Christiaen et al, 2014 ; Han et al, 2015 ; Li H. et al, 2015 ; Wang et al, 2016 ). However, limited studies have been conducted on the regulation of biofilm formation in Lactobacillus by the AI-2/LuxS QS system.…”
