  1. 1. Presence and viability of enterotoxigenic Escherichia coli (ETEC) in aquatic environments

    Author : Åsa Lothigius; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Enterotoxigenic Escherichia coli; ETEC; real-time PCR; aquatic environments; VBNC; resuscitation; infant mouse model;

    Abstract : Enterotoxigenic Escherichia coli (ETEC) is one of the major causes of diarrhoea among children in developing countries and in travelers to these regions. The bacteria are spread via contaminated water and food, and surface and drinking water in developing countries has been found to harbor these organisms. READ MORE

  2. 2. Whole Genome Sequencing of Enterotoxigenic Escherichia coli

    Author : Astrid von Mentzer; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : ETEC; whole genome sequencing; evolution; colonization factor; reverse genetics;

    Abstract : Enterotoxigenic Escherichia coli (ETEC) infections are a common cause of diarrhea but little is known about the evolution and genomic composition of ETEC. The main aim of this thesis was to generate a large collection of whole genome sequenced ETEC isolates to study the evolution of such bacteria on a global level and to search for novel colonization factors (CFs) using both classical and cutting-edge genomic techniques.

  3. 3. Virulence factors and clonal relatedness of enterotoxigenic Escherichia coli (ETEC) isolated from children with diarrhoea in Bolivia

    Author : Claudia Rodas Miranda; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Enterotoxigenic Escherichia coli; Virulence factors; Bolivia; Children; Severity of disease; Relatedness;

    Abstract : Enterotoxigenic Escherichia coli (ETEC) is one of the major causes of diarrhoea in children under five years of age in developing countries and in travellers to these settings. To cause disease, ETEC must be able to colonize the small intestine and produce heat-stable enterotoxin (ST) or heat-labile toxin (LT) or both toxins. READ MORE

  4. 4. Studies of Carbohydrate-Binding Proteins from Enterotoxigenic Escherichia coli

    Author : Lena Jansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Carbohydrate recognition; ETEC colonization factors; CFA I fimbriae; CS6 protein; heat-labile enterotoxin;

    Abstract : Knowledge about the carbohydrate binding specificity of pathogens can give an increased understanding of their virulence strategies, and is also of importance for the development of anti-adhesive therapies and vaccines. Enterotoxigenic Escherichia coli (ETEC) is a well-known causative agent of diarrheal disease. READ MORE

  5. 5. Studies on the Expression and Regulation of Enterotoxins and Colonization Factors in Enterotoxigenic Escherichia coli (ETEC)

    Author : Matilda Nicklasson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : ETEC; heat-stable enterotoxin; heat-labile enterotoxin; colonization factors; CS5; CS6; virulence gene expression; in vivo and in vitro; genetic variability;

    Abstract : Enterotoxigenic Escherichia coli (ETEC) is one of the most common causes of acute watery diarrhoea in developing countries, particularly among local children less than five years and is also the most common cause of diarrhoea in travellers to ETEC endemic areas. The infection is transmitted by ingestion of contaminated food and water and the disease is established in the small intestine. READ MORE
