  1. 6. Evolutionary genomics of host-microbe interactions

    Författare :Elin Videvall; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; host; microbiota; avian malaria; ostrich; parasite; dual RNA-seq;

    Sammanfattning : The microbes living inside hosts have highly important consequences for host health and fitness. From the host’s perspective, some microbes exhibit mutualistic tendencies, others parasitic, and some commensal, but this is context-dependent and opportunistic lifestyles are widespread in nature.

  3. 7. A microarray analysis of the host response to infection with Francisella tularensis

    Författare :Henrik Andersson; Anders Sjöstedt; David Stenger; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; tularemia; host response; gene expression; microarray; Clinical bacteriology; Klinisk bakteriologi;

    Sammanfattning : Francisella tularensis is a gram-negative bacterium that is the cause of the serious and sometimes fatal disease, tularemia, in a wide range of animal species and in humans. The response of cells of the mouse macrophage cell line J774 to infection with Francisella tularensis LVS was analyzed by means of a DNA microarray. LÄS MER

  4. 8. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms

    Författare :Gabriela Wassing; Ann-Beth Jonsson; Elena Vikström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Lactobacillus; host responses; EGR1; antimicrobial peptides; hBD2; A20; biofilm; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. LÄS MER

  5. 9. Studies of the pathogenesis of Enterohemorrhagic Escherichia coli infections: pathogen virulence factors and host response

    Författare :Carla Calderon Toledo; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; host-pathogen; MyD88; TLRs; LEE; Shiga toxin; HUS; EHEC; EPEC; immune response; virulence factors;

    Sammanfattning : Enterohemorrhagic Escherichia coli (EHEC) is a highly virulent pathogen that can cause diarrhea and a life-threatening disease known as hemolytic uremic syndrome. EHEC possess an array of virulence factors that can exert severe consequences in the host. Shiga toxin constitutes a key virulence factor. LÄS MER

  7. 10. Mechanisms of microbial-host interaction during asymptomatic bacteriuria

    Författare :Jenny Grönberg Hernandez; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asymptomatic bacteriuria; Urinary tract infection; Escherichia coli 83972; IRF3; TLR4; Evolution; host response; promoter polymorphisms; transcription; P fimbriae; Type 1 fimbriae;

    Sammanfattning : Urinary tract infections (UTIs) present an interesting and relevant model for studying microbial adaptation. After establishing significant numbers, the bacteria either cause severe disease, or an asymptomatic carrier state resembling the normal flora at other mucosal sites. LÄS MER
