(Submitter supplied) Clostridium difficile is an emergent human pathogen and the most common cause of nosocomial diarrhea. Our recent deep-sequencing data strongly suggest the importance of RNA-based mechanisms for the control of gene expression in C. difficile. The RNA chaperon protein Hfq is a key component of post-transcriptional regulatory network in various bacterial systems. In an effort to understand the function of Hfq in C. more...

(Submitter supplied) The Gram-positive bacterium Clostridium difficile, a leading cause of antibiotic-associated pseudomembranous colitis, has received increasing attention due to a rising incidence of clinical C. difficile infections (CDI). Despite progress understanding bacterial factors that promote CDI-associated morbidity and mortality, many fundamental aspects of C. difficile biology remain to be explored. Compared to other Gram-positive pathogens, little is known about the bacterium’s transcriptome architecture and in particular mechanisms of post-transcriptional control. more...

(Submitter supplied) Compartment-specific control of gene expression during Bacillus subtilis sporulation is governed by a cascade of four sigma factors, sigmaF and sigmaG in the forespore and sigmaE and sigmaK in the mother cell. In this work, we combined transcriptional analyses and transcriptional start site mapping to define the sigmaF, sigmaE, sigmaG and sigmaK regulons in Clostridium difficile. A total of about 225 genes were under the control of these sigma factors: 25 in the sigmaF regulon, 97 sigmaE-dependent genes, 50 sigmaG-governed genes and 56 genes specifically controlled by sigmaK. more...

(Submitter supplied) The obligate anaerobic, enteric pathogen Clostridioides difficile persists in the intestinal tract by forming antibiotic resistant endospores that contribute to relapsing and recurrent infections. Despite the importance of sporulation for C. difficile pathogenesis, environmental cues, and molecular mechanisms regulating sporulation initiation remain ill defined. Here, using RIL-seq to capture the Hfq-dependent RNA-RNA interactome, we discovered a network of small RNAs that bind to mRNAs encoding sporulation-related genes. more...

(Submitter supplied) Purpose: The goal of this study was to identify genes whose expression is induced during sporulation in a Spo0A-, σF-, σE-, σG-, and σK-dependent manner. Methods: Whole genome RNA sequencing was performed on wildtype, spo0A-, sigF-, sigE-, sigG-, and sigK- C. difficile strains (strain 630 background; JIR8094 = parent strain), and the transcriptional profiles of the different mutants during growth on 70:30 agar plates were determined using an Illumina HiSeq1000. more...

(Submitter supplied) Stenotrophomonas maltophilia is an important opportunistic pathogen affecting primarily hospitalized and immuno-compromised hosts. We constructed an hfq deletion mutant (Delta-hfq) of S. maltophilia, and compared the behaviour of wild-type and Delta-hfq S. maltophilia cells in a variety of assays. Differential RNA sequencing analysis (dRNA-seq) of RNA isolated from S. maltophilia wild-type and Delta-hfq strains showed that Hfq regulates expression of genes encoding flagellar and fimbrial components, transmembrane proteins, as well as enzymes involved in different metabolic pathways. more...
