  2. 11. Urinary tract infections in pregnancy : studies in vivo and in vitro

    Author : Musa Sekikubo; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The risk of urinary tract infection (UTI) in pregnant women is increased and predisposes them to acute pyelonephritis together with poor pregnancy outcomes. Increased frequency of micturition, nocturia and lower abdominal discomfort are common non-specific complaints during pregnancy, which render clinical diagnosis of UTI inaccurate. READ MORE

  4. 12. Regulatory mechanisms involved in pathoadaptation of extraintestinal pathogenic Escherichia coli

    Author : Nikola Zlatkov; Bernt Eric Uhlin; Åke Forsberg; Sun Nyunt Wai; Eliora Ron; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ExPEC; PAIs; pathoadaptation; citrate; metabolism; filamentation; toxins; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Abstract : Establishment of commensal bacteria within a new niche of their host usually promotes the transition from commensalism to pathogenicity. Extraintestinal Pathogenic Escherichia coli (ExPEC) represent different pathovars with biphasic lifestyle – they can reside in the gut as commensals or they can escape and cause diseases elsewhere in the human body.

  5. 13. Mucosal receptors involved in pathogen recognition and host defence

    Author : Majlis Svensson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nefrologi; Urologi; nephrology; Urology; Infections; Infektioner;

    Abstract : Urinary tract infection is the most common infection in man. P fimbriae are virulence factors of uro-pathogenic Escherichia coli. They are expressed by 70-90 % of acute pyelonephritis isolates and up to 100% of the most virulent isolates that cause bacteremia. READ MORE

  6. 14. Studies of the pathogenesis of hemolytic uremic syndrome and thrombotic thrombocytopenic purpura

    Author : Diana Karpman; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatri; Pediatrics; tumor necrosis factor; interleukin 6; von Willebrand factor; apoptosis; lipopolysaccharide; shiga-like toxin; Escherichia coli O157:H7; Hemolytic uremic syndrome; thrombotic thrombocytopenic purpura; Urology; nephrology; Urologi; nefrologi;

    Abstract : This study investigated the pathogenesis of hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). (1) The relative roles of lipopolysaccharide and Shiga-like toxin-2 were studied in a mouse model of Escherichia coli O157:H7 infection. READ MORE

  7. 15. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota

    Author : Nahid Karami; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ampicillin; tetracycline; in vivo fitness; persistence; gene transfer; intestinal; blaTEM Escherichia coli;

    Abstract : Microbial resistance to antibiotics is a growing problem worldwide. Resistance develops not only in microbes which are the targets of the antibiotic treatment, but also in those belonging to the normal microbiota of the treated host. Little is known on the ecological consequences of antibiotic resistance in commensal bacteria. READ MORE
