1. 1. 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. 2. The genetics of antibiotic production and the role of antibiotics in biological control of Erwinia amylovora by Erwinia herbicola

   Författare :Sandra A. I. Wright; Cornell University; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biological sciences; fire blight; pantocin; Plant pathology; Microbiology; Molecular biology; 0480:Plant pathology; 0307:Molecular biology; 0410:Microbiology;

   Sammanfattning : Erwinia herbicola is an epiphyte of apple and pear with potential as a biocontrol agent of Erwinia amylovora, which causes fire blight. This research aimed to assess the relative role of antibiotics produced by E. herbicola, Eh318 as a mechanistic basis for biocontrol. LÄS MER

4. 3. Controlling virulence in Yersinia pseudotuberculosis through accumulation of phosphorylated CpxR

   Författare :Edvin Thanikkal; Matthew Francis; Andrew Darwin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Y. pseudotuberculosis; CpxA; CpxR; invasin; RovA; RovM; T3SS; virulence; transcriptional regulation; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

   Sammanfattning : Like many Gram-negative bacteria, the food-borne pathogen Yersinia pseudotuberculosis harbours different regulatory mechanisms to maintain an intact bacterial envelope especially during exposure to extracytoplasmic stress (ECS). The CpxA-CpxR two component regulatory system is one such ECS-responsive regulatory mechanism. LÄS MER

5. 4. Coordinating type III secretion system biogenesis in Yersinia pseudotuberculosis

   Författare :Jyoti Mohan Gurung; Matthew S Francis; Maria Fällman; Dirk Linke; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pseudotuberculosis; type III secretion system; YscX; YscY; YopN; TyeA; secretion signal; N-terminal region; site-directed mutagenesis; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

   Sammanfattning : Various Gram-negative bacteria utilize type III secretion system (T3SS) to deliver effectors into eukaryotic host cells and establish mutualistic or pathogenic interactions. An example is the Ysc-Yop T3SS of pathogenic Yersinia species. LÄS MER

7. 5. Twin-arginine translocation in Yersinia : the substrates and their role in virulence

   Författare :Ummehan Avican; Åke Forsberg; Åsa Sjöling; Umeå universitet; []
