  2. 6. Molecular epidemiology of coagulase-negative staphylococci in hospitals and in the community

    Author : Micael Widerström; Johan Wiström; Tor Monsen; Anders Sjöstedt; Bo Söderquist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; staphylococcus epidermidis; staphylococcus saprophyticus; electrophoresis; gel; pulsed-field; genetic diversity; methicillin-resistance; UTI; drug resistance; multiple; bacterial; epidemiology; molecular; cross infection; molecular sequence data; Medical microbiology; Medicinsk mikrobiologi; Clinical bacteriology; Klinisk bakteriologi; Infectious diseases; Infektionssjukdomar; Clinical Bacteriology; klinisk bakteriologi; mikrobiologi; Microbiology; Infectious Diseases; infektionssjukdomar;

    Abstract : Background Coagulase-negative staphylococci (CoNS) and in particular Staphylococcus epidermidis have emerged as major pathogens primarily causing nosocomial infections in patients with indwelling medical devices. These infections are often caused by multidrug-resistant strains of S. epidermidis (MDRSE). READ MORE

  4. 7. RsbX and stress response in Listeria monocytogenes

    Author : Ana Henriques de Oliveira; Jörgen Johansson; Cormac Gahan; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 8. Characterization and persistence of potential human pathogenic vibrios in aquatic environments

    Author : Betty Collin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbiology; Vibrio spp.; Mozambique; Sweden; Mytilus edulis; Vibrio cholerae; Vibrio parahaemolyticus; persistence;

    Abstract : Vibrio spp., natural inhabitants of aquatic environments, are one of the most common causes of bacterial gastroenteritis in the world, being spread to humans via the ingestion of seafood, contaminated drinking water or exposure to seawater. The majority of Vibrio spp. are avirulent, but certain strains may sporadically be human pathogenic. READ MORE

  6. 9. Evolutionary Dynamics of Mutation and Gene Transfer in Bacteria

    Author : Peter A Lind; Dan I Andersson; J. Arjan G. M. de Visser; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fitness cost; bacterial evolution; gene amplification; mutational biases; GC content; synonymous substitutions; horizontal gene transfer; experimental evolution; Bacteriology; Bakteriologi; Microbiology; Mikrobiologi; Genetics; Genetik; Biology; Biologi; Mikrobiologi; Microbiology;

    Abstract : The study of bacterial evolution is fundamental for addressing current problems of antibiotic resistance and emerging infectious diseases and lays a solid foundation for successful and rational design in biotechnology and synthetic biology. The main aim of this thesis is to test evolutionary hypotheses, largely based on theoretical considerations and sequence analysis, by designing scenarios in a laboratory setting to obtain experimental data.

  7. 10. Antibiotic interactions and selection for resistance in biofilms

    Author : Po-Cheng Tang; Dan I. Andersson; Karin Hjort; Mark Webber; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotics; Mikrobiologi; Microbiology;

    Abstract : The challenges posed by antibiotic-resistant bacteria in treating infections, particularly those associated with biofilms, require a deeper understanding of this lifestyle and its connection to resistance selection. Additionally, gaining insights into drug interactions is crucial for enhancing combination treatment efficacy and mitigating resistance development. READ MORE
