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

    Author : Björn Wullt; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 17. Species interactions govern evolutionary and ecological effects of population harvesting

    Author : Anna Gårdmark; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; population harvesting; species interactions; ecological community; Ekologi; Ecology; competition; predation; fisheries; spatial dynamics; maturation; population dynamics; life-history evolution; adaptation;

    Abstract : Harvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment.
