    Sammanfattning : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. LÄS MER

  2. 2. The role of P fimbriae for Escherichia coli establishment and mucosal inflammation in the human urinary tract

    Detta är en avhandling från Department of Urology, Clinical Sciences, Lund University

    Sammanfattning : Bacterial adhesion to the bladder mucosa is a critical step for the establishment of Escherichia coli bacteriuria. The P-fimbriae, encoded by the pap gene cluster, are considered as virulence factors but the mechanisms have been debated. This study defined the roles for P fimbriation during the early colonization of the human urinary tract. LÄS MER

  3. 3. Mechanisms of microbial-host interaction during asymptomatic bacteriuria

    Detta är en avhandling från Division of Microbiology, Immunology and Glycobiology - MIG

    Författare :Jenny Grönberg Hernandez; Lund University.; Lunds universitet.; [2013]
    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

  4. 4. Molecular determinants of disease severity in urinary tract infection

    Detta är en avhandling från Lund University: Faculty of Medicine

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptomatic bacteriuria; urinary tract infection; acute pyelonephritis; cystitis; Escherichia coli 83972; host response; NlpD; RNA Polymerase II; transcription regulation; inflammasome; Il-1β; ASC; NLRP-3; hyper-inflammatory disorder; MMP-7; IL-1RA; genetic susceptibility; IRF-7; siRNA therapy; P fimbriae; type 1 fimbriae;

    Sammanfattning : In the urinary tract, Escherichia coli infection may result in life-threatening disease, or asymptomatic bacterial carriage, comparable to bacterial commensalism in the gut. Pathogenic strains trigger a disease provoking host response which differs depending on the infected organ. LÄS MER
