  2. 1. Enterohemorrhagic Escherichia coli, EHEC.Microbiological diagnosis, characterisation and clinical bacteriological aspects

    Author : Christina Welinder-Olsson; Göteborgs universitet; []
    Keywords : Escherichia coli; EHEC; VTEC; verocytotoxin; PFGE; EHEC-hemolysin; aerobactin; diarrhoea; HUS;

    Abstract : Enterohemorrhagic Escherichia coli (EHEC) constitutes a group of E. coli that in the past two decades has been the cause of several outbreaks of gastrointestinal disease. The microorganism causes hemorrhagic colitis (HC) and haemolytic uremic syndrome (HUS) in 5-10% of the patients, 30% of the HUS patients develop remaining kidney injuries. READ MORE

  4. 2. Visualizing the dynamic interplay between the host and bacterial pathogen : a real-time study of renal infection

    Author : Lisa Månsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The human body is a complex entity capable of handling a variety of pathogenic challenges without developing disease symptoms. Sometimes, however, the pathogens are superior and the host immune system is unable to clear the infection. READ MORE

  5. 3. Virulence mechanisms of two gram negative bacteria : studies on Escherichia coli hemolysin HlyA and on the interaction of Brucella abortus with non-phagocytic cells

    Author : Caterina Guzman-Verri; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Virulence factors may be classified in two general groups: those that cause damage to the host and those that promote bacterial colonization and invasion. In this study, the tissue damaging Escherichia coli hemolysin HlyA and the mechanism of internalization of the intracellular parasite Brucella abortus were investigated. READ MORE

  6. 4. Renal cell death in urinary tract infections : role of E. coli toxins

    Author : Ming Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Pyelonephritis; Escherichia coli toxins; ERK; LPA; cell death; carbon monoxide; hemolysin; nitric oxide; heme oxygenase-1; dexamethasone; kidney development;

    Abstract : Febrile urinary tract infections (UTI) are common bacterial illnesses in children. Several follow up studies have shown that 10-15 % of infants with pyelonephritis will develop permanent renal damage, i.e., renal scars, which in turn may lead to chronic diseases such as hypertension and renal insufficiency.

    Abstract : In an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. READ MORE
