(Submitter supplied) To combat dental implant-associated infections, there is a need for novel materials which effectively inhibit bacterial biofilm formation. In the present study, a titanium surface functionalization based on the “slippery liquid-infused porous surfaces” (SLIPS) principle was analyzed in an oral flow chamber system. The immobilized liquid layer was stable over 13 days of continuous flow. With increasing flow rates, the surface exhibited a significant reduction in attached biofilm of both the oral initial colonizer Streptococcus oralis and an oral multi-species biofilm composed of S. more...

(Submitter supplied) Investigation of whole genome gene expression levels of P. gingivalis W83, F. nucleatum DSMZ 25586, S. sanguinis SK36, A. actinomycetemcomitans HK1651, S. mutans UA159 in an 24 h old culture. Additionally, whole genome gene expression level changes of S. mutans UA159 biofilm cells after co-cultivation with S. mitis ATCC 11843 were compared to its single species biofilm growth after 24 h. Aim: Demonstration of the usefulness of a five-species gene expression array. more...

(Submitter supplied) Streptococcus pneumoniae is a Gram positive bacterium that causes severe invasive infection such as pneumonia, septicemia, meningitis and otitis media especially in children, the elderly and immune-compromised patients. Pneumococcal colonization and disease is often associated with biofilm formation. Bacteria in biofilms exhibit elevated resistance both to antibiotics and to host defense systems, which often results in persistent and difficult-to-treat infections. more...

(Submitter supplied) In vitro comparative transcriptome analysis was carried to determine genes that are differentially expressed in S. mutans biofilm compared with free-living cells. DNA-microarray analyses indicated that about 12 % of genes showed significant differential expression: 139 were activated and 104 were repressed in biofilm vs. planktonic environment.

(Submitter supplied) Porphyromonas gingivalis (P. gingivalis) W83 cultures in early exponential phase were supplemented with 0.1% galactose or vehicle control. The cultures were then permitted to grow anaerobically at 37°C for 3 hours, which corresponds to approximately one doubling of P. gingivalis. At this point, RNA extraction was performed using the cultures, and these samples were processed and submitted for RNA sequencing using an Illumina platform. more...

(Submitter supplied) To examine the early (4h) miRNAs responses of differentiated macrophages to LPS challenge, we performed global miRNA profiling using the Nanostring nCounter technology, a multiplexed, color-coded probe assay. Of the 653 probes present on the assay, we detected expression of ~200 (30%) miRNAs across all samples.

(Submitter supplied) Polyphosphate (polyP) is a ubiquitous and abundant compound found in bacteria, fungi, algae, plant, and animals. Among roles of intracellular polyP in bacteria are resistance and survival in the stationary phase of the growth against stress and stringent condition. Therefore, intracellular polyP is considered as a virulence factor of bacteria. In contrast, exogenous polyP has an antimicrobial activity against a variety of microorganisms. more...
