(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) Using DNA-microarrays analysis 39 differentially expressed genes were identified in 200 vs. 100 microns biofilms, which might be associated with thickness of S. mutans biofilm. Using DNA-microarrays analysis 29 differentially expressed genes were identified in 400 vs. 100 microns biofilms of S. mutans.

(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) In the oral biofilm, the mitis streptococci are among the first group of organisms to colonize the tooth surface. Their proliferation is thought to be an important factor required for antagonizing the growth of cariogenic species such as Streptococcus mutans. In this study, we used a 3-species mixed culture to demonstrate that another ubiquitous early colonizing species, Veillonella parvula, could greatly impact the competitive outcome of a mixed culture of S. more...

(Submitter supplied) We performed comparative analysis of transcriptomes of S. mutans in single biofilms and in mixed-biofilms with A. actinomycetemcomitans. We also compared the transcriptomic profiles of A. actinomycetemcomitans in single biofilms and A. actinomycetemcomitans in mixed biofilms with S. mutans. Finally we looked at the changes in gene expression in both organisms in time.
