(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...

(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) Treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections is dependant on the efficacy of last-line antibiotics like vancomycin. Vancomycin treatment failure is most commonly linked to the emergence of vancomycin-intermediate resistance in clincal isolates (termed VISA). These isolates have not acquired resistance genes but appear to accumulate a heterogenous collection of single nucleotide polymerisms that collectively alter the physiology of the cell to increase vancomycin tolerance. more...

(Submitter supplied) Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial pathogen responsible for high levels of human morbidity and mortality. MRSA co-ordinates expression of an array of bacterial factors involved in antimicrobial resistance, nutrient acquisition and immune evasion in the host. Post-transcriptional regulation by small RNAs (sRNAs) has emerged as an important mechanism for the control of MRSA virulence. 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) UV-crosslining of protein-RNA complexes was employed to capture sRNA-mRNA interactions occuring on the RNA degradosome protein, RNase E, in enterohaemorhaggic E. coli. Abstract from associated mansucript: In many organisms small regulatory RNAs (sRNA) play important roles in the regulation of gene expression by base-pairing to specific target mRNAs. In enterohaemorrhagic E. coli (EHEC), sRNAs are encoded by both the “core” genome and in numerous horizontally acquired pathogenicity islands. more...

(Submitter supplied) Resistance to antibiotics is an emerging problem and necessitates novel antibacterial therapies. Cervimycins A‒D are natural products of Streptomyces tendae HKI 0179 with promising activity against multidrug resistant staphylococci and vancomycin resistant enterococci. We studied the mode of action of cervimycin C and D by selection of cervimycin resistant (CmR) Staphylococcus aureus strains. Genome sequencing of CmR mutants revealed amino acid exchanges in the essential histidine kinase WalK, the Clp protease proteolytic subunit ClpP or the Clp ATPase ClpC, and the heat shock protein DnaK. more...

(Submitter supplied) By shaping gene expression profiles, small RNAs (sRNAs) enable bacteria to efficiently adapt to changes in their environment. To better understand how Escherichia coli acclimatizes to nutrient availability, we performed UV cross-linking, ligation and sequencing of hybrids (CLASH) to uncover Hfq-associated RNA-RNA interactions at specific growth stages. We demonstrate that Hfq CLASH robustly captures bona fide RNA-RNA interactions identified hundreds of novel sRNA base-pairing interactions, including many sRNA-sRNA interactions and involving 3’UTR-derived sRNAs. more...

(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) Staphylococcus aureus is an adaptable human pathogen causing life-threatening endocarditis and bacteraemia. Methicillin-resistant S. aureus (MRSA) is alarmingly common, and treatment is confined to last-line antibiotics. Vancomycin is the treatment of choice for MRSA bacteraemia and vancomycin treatment failure is often associated with vancomycin-intermediate S. aureus strains termed VISA. The regulatory 3’ UTR of vigR mRNA contributes to vancomycin tolerance in the clinical VISA isolate JKD6008 and upregulates the lytic transglycosylase IsaA. more...

(Submitter supplied) A key challenge for understanding the role(s) played by short, non-coding RNAs (sRNAs) in bacteria is identifying the mRNA targets regulated by the sRNAs. Because the Hfq protein mediates the interactions between many sRNAs and the corresponding target mRNAs, one apporach to identify the mRNA targets of sRNAs is to capture sRNA:mRNA interactions occuring on Hfq by exposing cells to UV-irradiation, which forms cross-links between nucleic acids and proteins. more...
