(Submitter supplied) Sortase-assembled pili contribute to virulence in many Gram-positive bacteria. In Enterococcus faecalis, the endocarditis and biofilm-associated pilus (Ebp) is polymerized on the membrane by sortase C (SrtC) and attached to the cell wall by sortase A (SrtA). In the absence of SrtA, polymerized pili remain anchored to the membrane (i.e. off-pathway). Here we show that the high temperature requirement A (HtrA) bifunctional chaperone/protease of E. more...

(Submitter supplied) Enterococcus faecalis is a commensal bacterium in the gastrointestinal tract (GIT) of humans and other organisms. Outside of the GIT, E. faecalis can cause infections in root canals, wounds, surgical sites, the urinary tract, and on heart valves. Many of these infections can be polymicrobial, and a variety of toxins and nutritional signals influence interactions between E. faecalis and other microbes. more...

(Submitter supplied) The goal was to identify genes regulated by YvcL (EF0768) by assessing changes in the yvcL deletion mutant relative to the isogenic wild-type. Wild-type E. faecalis OG1 and the mutant lacking yvcL were cultured in Mueller-Hinton broth to exponential phase. Total RNA was purified, depleted for rRNA, and subjected to preparation of mRNA libraries.

(Submitter supplied) There had a total number of 804 genes with transcript difference, including 482 up-regulated genes and 322 down-regulated genes. Enrichment analysis of those 804 different transcript gene sets was performed to explore the biological effects and the corresponding pathways that are significantly associated on GO and KEGG (Padj <0.05 as the threshold for significant enrichment). In the GO functional enrichment analysis, all differential genes were significantly enriched into 65 GO Terms, among them there had 50 GO terms belonging to BP (Biological Process). more...

(Submitter supplied) Enterococcus faecalis is commonly isolated from different wound types. However, despite its prevalence, the pathogenic mechanisms of E. faecalis during wound infections remain poorly understood. We adopted an in vivo E. faecalis transposon sequencing and RNA sequencing approach to identify fitness determinants that are crucial for replication and persistence of E. faecalis during wound infections in a mouse model. more...

(Submitter supplied) The goal of this study was to determine how the method of pooling (combining mutants) for bacteral Tn libraries affected mutant distribution. Previously we generated a pooled version of a~6,800 Tn mutant library in Enterococcus faecalis OG1RF by plating and scraping individual mutants. Here, we combined liquid cultures grown in deep well plates. DNA from the new pooled library was extracted, and TnSeq was used to compare mutant distribution between the old (plate scraping) and new (liquid pooling) Tn library formats. more...

(Submitter supplied) The microbiome has revealed itself as a key player in health and disease. To better understand its role, in addition to microbial diversity, it is important to understand species-specific activity and gene expression. While metatranscriptomics investigates mRNA abundance2, it does not inform about faster post-transcriptional regulation3. Although prokaryotic translation is a common target for antibiotics, a direct measurement of microbiome ribosome dynamics remains inaccessible. more...

(Submitter supplied) We investigated the RNA-protein interactome of Enterococcus faecalis V583 and Enterococcus faecium Aus0004 by native gradient fractionation of complexes coupled to RNA-sequencing. Whole bacterial cell lysates were analysed by size and density in a glycerol gradient. At native conditions, RNA-protein complexes stay intact and sediment as a whole. Sedimentation profiles of individual RNAs appear correlated in case of interaction in a complex. more...

Upon colonization of the gastrointestinal tract, C. difficile is exposed to a rapidly changing polymicrobial environment and a dynamic metabolic milieu. Despite the link between the gut microbiota and susceptibility to C. difficile, the impact of synergistic interactions between the microbiota and pathogens on the outcome of infection is largely unknown. more...

(Submitter supplied) The goal was to identify genes that are regulated by cell wall stress (bacitracin treatment) in wild-type cells but not in mutant cells lacking CroR, thereby revealing genes of the CroR regulon. Cells of a mutant lacking CroR or its otherwise isogenic wild-type E. faecalis OG1 were cultured in Mueller-Hinton broth and treated (or not) with bacitracin for 15 min. Total RNA was purified, depleted for rRNA, and subjected to preparation of TruSeq stranded mRNA libraries before sequencing on a NextSeq 550 (76-bp single read run).

(Submitter supplied) Enterococcus faecalis is often co-isolated with Pseudomonas aeruginosa in mixed-species biofilm-associated infections of wounds and the urinary tract. As a defence strategy, the host innately restricts iron availability at infection sites. Despite their co-prevalence, the polymicrobial interactions of these two pathogens in low iron conditions, such as those found in the host, remains unexplored. Here we show that E. more...

(Submitter supplied) Enterococcus faecalis is a natural inhabitant of the human gastrointestinal tract. In a healthy physiological state of the gut (eubiosis), E. faecalis is a subdominant species in the intestinal microbiota. When the intestinal homeostasis is disrupted (dysbiosis), it becomes dominant species and can cause infections. The taurocholate bile acid (TCA) becomes prominent during dysbiosis. This experiment aimed to better understand how E. more...
