  1. 1. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract

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

    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. 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

  3. 3. Mucosal immunity in the respiratory tract The role of IgA in protection against intracellular pathogens

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Ariane Rodríguez; Stockholms universitet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucosal immunity; respiratory tract; IgA; intracellular pathogens; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi;

    Sammanfattning : The lungs and upper airways are mucosal surfaces that are common site for infection with an enormous variety of inhaled pathogens. Therefore, induction of immune responses in the respiratory tract is crucial for protection against respiratory diseases. One of the pathogens infecting the host via the respiratory tract is Mycobacterium Tuberculosis. LÄS MER

  4. 4. 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

    Författare :Björn Wullt; Lund University.; Lunds universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; Microbiology; asymptomatic bacteriuria; urinary tract infections; deliberate colonization; E. coli 83972; P-fimbriae; Mucosal host response; IL-6; IL-8; neutrophils; regulation.; GFP; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    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

  5. 5. Exploring probiotics-host interactions

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

    Författare :Shokoufeh Karimi; Sveriges lantbruksuniversitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Lactobacillus reuteri, a ubiquitous inhabitant of the mammalian gastrointestinal (GI) tract has known health-promoting effects and various strains are commercially available as probiotics. Several probiosis mechanisms have been suggested in L. reuteri’s mode of action, but the mediators and factors involved are not well understood. LÄS MER
