TnSeq of Enterococcus faecalis OG1RF Tn mutants in biofilm and planktonic samples

Project description:Enterococcus faecalis is a common commensal organism and a prolific nosocomial pathogen that causes biofilm-associated infections. Numerous E. faecalis OG1RF genes required for biofilm formation have been identified, but few studies have compared genetic determinants of biofilm formation and biofilm morphology across multiple conditions. Here, we cultured transposon (Tn) libraries in CDC biofilm reactors in two different media and used Tn sequencing (TnSeq) to identify core and accessory biofilm determinants, including many genes that are poorly characterized or annotated as hypothetical. Multiple secondary assays (96-well plates, submerged Aclar, and MultiRep biofilm reactors) were used to validate phenotypes of new biofilm determinants.

Transcriptomes of Enterococcus faecalis OG1RF and OG1RF Δbph in planktonic culture

Project description:Liquid cultures of Enterococcus faecalis OG1RF and OG1RF Δbph were grown in tryptic soy broth without added dextrose (TSB-D) for 2 and 4 hr. At each time point, the transcriptomes were compared to identify differentially expressed genes in the Δbph mutant.

Genome-wide Analysis of Enterococcus faecalis OG1RF Gene Expression During Infection

Project description:Changes in Enterococcus faecalis OG1RF gene expression during infection in a rabbit model of subdermal abscess formation were studied using microarray analysis. Samples assayed in arrays consisted of the input inoculum and total RNA collected from the subdermal chambers at 2 and 8 hours post-inoculation. Alexa647-labeled samples were co-hybridized with 0.5 micrograms of sheared OG1RF genomic DNA labeled with Cy3 as a standard reference between chips. Four biological replicates were performed for each of the 3 time points.

Transcriptome analysis of Enterococcus faecalis OG1 delta-EF2638 mutant

Project description:Analysis of changes in gene expression in Enterococcus faecalis OG1 delta-EF2638 mutant compared to wild-type OG1 strain. The deletion mutant has a growth defect when grown with aeration The mutant presented in this study is described and characterized in Vesic, D. and Kristich, C.J. 2012. A Rex-family transcriptional repressor influnces H2O2 accumulation by Enterococcus faecalis. (submitted for publication) Microarray analysis was done using RNA isolated from two independent cultures of wild-type Enterococcus faecalis OG1 and two independent cultres of Enterococcus faecalis OG1 delta-EF2638 mutant; each RNA sample was subjected to triplicate hybridization (technical replicates) . Microarrays were custom designed to investigate expression of ORFs in Enterococcus faecalis OG1RF genome. The arrays were designed based on the OG1RF annotation generated with the Rapid Annotation Using Subsystem Technology (RAST) server (Aziz et. al. 2008. BMC Genomics 9:75), as described in Frank et al (2012) Infect. Immun. 80:539. The aim was eighteen probe pairs per ORF, each of which is present in triplicate.

Transcriptomic response of Enterococcus faecalis to iron excess

Project description:To further investigate the homeostatic response of E. faecalis to Fe exposure, we examine the whole-genome transcriptional response of wild-type (WT) exposed to non toxic Fe excess. This experiment correspond the work titled Transcriptomic response of Enterococcus faecalis to iron excess (work in preparation) A four chip study using total RNA recovered from four separate wild-type cultures of Enterococcus faecalis OG1RF, two controls samples (N medium growth) and two iron samples (N medium gowth with 0.5 mM Fe-NTA). Each chip measures the expression level of 3,114 genome genes from Enterococcus faecalis strain V583 (A7980-00-01).
