  1. 16. Multifaceted RNA-mediated regulatory mechanisms in Streptococcus pyogenes

    Författare :Anaïs Le Rhun; Emmanuelle Charpentier; Franz Narberhaus; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Streptococcus pyogenes; small RNAs; CRISPR; Cas9; tracrRNA; RNases; gene expression; RNA sequencing; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : Bacterial pathogens rely on precise regulation of gene expression to coordinate host infection processes and resist invasion by mobile genetic elements. An interconnected network of protein and RNA regulators dynamically controls the expression of virulence factors using a variety of mechanisms. LÄS MER

  2. 17. RsbX and stress response in Listeria monocytogenes

    Författare :Ana Henriques de Oliveira; Jörgen Johansson; Cormac Gahan; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; SigB; stressosome; RsbX; phosphorylation; growth; competitiveness; motility; energetic cost; homeostasis; stress response; virulence; invasion; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Sammanfattning : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. LÄS MER

  3. 18. Studies on regulatory networks governing virulence gene transcription in Staphylococcus aureus

    Författare :Erik Gustafsson; Högskolan i Skövde; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Naturvetenskap; Natural sciences;

    Sammanfattning : Staphylococcus aureus pathogenicity is dependent on the coordinated action of a number of virulence factors and the expression of these virulence factors is determined by several global regulators. The main regulator seems to be agr but there are several additional regulators (mostly sarA homologues) involved that mainly act downstream of agr. LÄS MER

  4. 19. Identification of Virulence Factors in Nematode-Trapping Fungi - Insights from Genomics, Transcriptomics and Proteomics

    Författare :Karl-Magnus Andersson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nematode-trapping fungi; comparative genomics; comparative transcriptomics; proteomics; virulence factors; parasitism;

    Sammanfattning : Nematode-trapping fungi are soil-living organisms with the unique ability to capture and infect free-living nematodes. The interest in studying these fungi arises from their potential use as biological control agents for plant- and animal-parasitic nematodes. LÄS MER

  5. 20. Gene expression and antibiotic resistance in Escherichia coli from Swedish inland waters

    Författare :Sirirat Poonlapthawee; Jana Jass; Per-Erik Olsson; Allan Sirsjö; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi;

    Sammanfattning : Extensive use of antibiotics both from human-medicine and veterinary sources are believed to provide selective pressure on bacteria that leads to an increase in antibiotic resistance in environmental waters. Contamination of antibiotic resistant microbes will raise human health risks. LÄS MER
