(Submitter supplied) Regulatory RNAs (sRNAs) are now considered as major players in many physiological and adaptive responses in pathogenic bacteria. sRNAs have been extensively studied in Gram-negative bacteria, but less information is available in Gram-positive pathogens. There is a spread of multidrug-resistant (MDR) opportunistic organisms, grouped as “ESKAPE” pathogens, which comprise enterococci, a leading cause of hospital-acquired infections and outbreaks with emergence of MDR isolates, especially vancomycin-resistant Enterococcus faecium (VREF). more...

(Submitter supplied) Streptococcus pneumoniae (pneumococcus) is a major human respiratory pathogen and a leading cause of bacterial pneumonia worldwide. Small regulatory RNAs (sRNAs), which often act by post-transcriptionally regulating gene expression, have been shown to be crucial for the virulence of S. pneumoniae and other bacterial pathogens. Over 170 putative sRNAs have been identified in S. pneumoniae TIGR4 strain (serotype 4) through transcriptomic studies, and a subset of these sRNAs have been further implicated in regulating pneumococcal pathogenesis. more...

(Submitter supplied) Coordinated protein-coding sequence transcriptional responses of Staphylococcus aureus to antimicrobial exposure are well described but little is known of the role of bacterial non-coding, small RNAs (sRNAs) in these responses. Here we used RNAseq to investigate the sRNA response of the epidemic multiresistant hospital ST239 S. Aureus strain JKD6009 and its vancomycin-intermediate clinical derivative, JKD6008, after exposure to four antibiotics representing the major classes of antimicrobials used to treat methicillin-resistant S. more...

(Submitter supplied) The enterococci comprise a genus of 49 low-GC content Gram-positive commensal species within the Firmicutes phylum that are known to occupy diverse habitats, notably the gastrointestinal core microbiota of nearly every phylum, including human. Of particular clinical relevance are two rogue species of enterococci, Enterococcus faecalis and the distantly related Enterococcus faecium, standing among the nefarious multi-drug resistant and hospital-acquired pathogens. more...

(Submitter supplied) In Staphylococcus aureus, hundreds of small regulatory or small RNAs (sRNAs) have been identified, yet this class of molecule remains poorly understood and severely understudied. sRNA genes are typically absent from genome annotation files, and as a consequence, their existence is often overlooked, particularly in global transcriptomic studies. To facilitate improved detection and analysis of sRNAs in S. more...

(Submitter supplied) Small RNAs have been found to control a broad range of bacterial phenotypes including tolerance to antibiotics. Vancomycin tolerance in multidrug resistance Staphylococcus aureus is correlated with dysregulation of small RNAs although their contribution to antibiotic tolerance in poorly understood. RNA-RNA interactome profiling techniques are expanding our understanding of sRNA-mRNA interactions in bacteria; however, determining the function of these interactions for hundreds of sRNA-mRNA pairs is a major challenge. more...

Methods: RNA was isolated from N. gonorrhoeae using the miRNeasy Micro Kit (Qiagen). Enrichment of mRNA was done using the Universal Ribodepletion Kit followed by Next Ultra Directional Library Preparation Kit for Illumina (NEB). The cDNA was sequenced on Illumina HiSeq 3000 platform with 100 bp paired end reads. 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...

(Submitter supplied) We have deep sequenced the small transcriptome of Escherichia coli growing in LB and in MOPS, in exponential and stationary phase, and analyzed the resulting reads by a novel pipeline STARPA (Stable RNA Processing Product Analyzer). Our analysis reveals over 14,000 small transcripts enriched during both growth stages. RNA samples were collected from total RNA pools or from crude ribosome pools and then size selected by electrophoresis to limit the products to 20-300nt.

(Submitter supplied) Small regulatory RNAs (sRNAs) represent a major mechanism of virulence regulation in several pathogens. To date, only three sRNAs have been described in GAS in any detail. To identify whether sRNAs are common within the GAS genome, we created a custom Affymetrix tiling microarray in which all intergenic regions (>49 bp) of the MGAS2221 genome were tiled at high density. Triplicate cultures of strain MGAS2221 in THY broth were grown to the exponential phase (O.D.600 of 0.5) of growth and RNA was isolated, converted to cDNA, fragmented, labeled, and hybridized to our custom array (one array per RNA sample [ hence three arrays total]). more...

(Submitter supplied) PEL is a small regulatory RNA that is present within the S. pyogenes genome. In some strains of S. pyogenes, the PEL sRNA regulates many of the known virulence factors produced by this pathogen. A genome-wide analysis of PEL-regulated genes had not been performed previously so we analyzed this by comparing the parental M1T1 isolate MGAS2221 with an isogenic PEL mutant. Comparing gene transcript levels between these two strains at the exponential and stationary phases of growth, we identified that PEL has no regulatory function in MGAS2221.

(Submitter supplied) Purpose: Small regulatory RNAs (sRNAs) are short transcripts that base-pair to mRNA targets or interact with regulatory proteins. sRNA function has been extensively studied in Gram-negative bacteria; comparatively less is known about sRNAs in Firmicutes. Here we investigate two sRNAs encoded by the virulence plasmid pXO1 of Bacillus anthracis, the causative agent of anthrax. We designated the sRNAs as as “XrrA” and “XrrB” (for pXO1-encoded regulatory RNA). more...

(Submitter supplied) Accurate annotation of regulatory RNAs is a complex task but nevertheless essential as sRNA molecular and functional studies ensue from it. Several formerly considered small RNAs (sRNA) are now known to be parts of UTR transcripts. In light of experimental data, we review hundreds of Staphylococcus aureus putative regulatory RNAs. We pinpoint those that are likely acting in trans and are not expressed from the opposite strand of a coding gene. more...
