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

    Author : Matilda Nicklasson; Göteborgs universitet; []
    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

  2. 2. Whole Genome Sequencing of Enterotoxigenic Escherichia coli

    Author : Astrid von Mentzer; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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. Structural analyses of carbohydrate receptors for enterotoxins and adhesins of enterotoxigenic Escherichia coli

    Author : Dani Zalem; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbohydrate recognition; glycosphingolipid; diarrheagenic E. coli; ETEC; heat-labile enterotoxin; colonization factor; AB5 toxins;

    Abstract : Carbohydrate-binding proteins expressed by microbes are key determinants in initiating and sustaining infections that account for millions of deaths each year. This thesis fo- cused on proteins integral to infections instigated by enterotoxigenic Escherichia coli (ETEC); estimated as the largest bacterial cause of diarrhea in the world with hundreds of millions of cases each year.

  4. 4. Vaccination against cholera and ETEC diarrhea and interventions to improve vaccine immune responses

    Author : Tanvir Ahmed; Göteborgs universitet; []
    Keywords : Vibrio cholerae; ETEC; oral vaccine; CS6; CFA I; Lewis blood group; zinc; breast feeding; T cell; B cell;

    Abstract : Vaccination against cholera and ETEC diarrhea and interventions to improve vaccine immune responses Abstract Vibrio cholerae O1 and enterotoxigenic Escherichia coli (ETEC) together account for the majority of bacterial causes of acute dehydrating diarrhea in children in Bangladesh. Vaccines should be considered as an important public health tool for prevention of these diarrheal diseases. READ MORE

  5. 5. Genetic diversity of the heat labile (LT) and heat stable (ST) toxins of human enterotoxigenic Escherichia coli (ETEC): New insights into polymorphism, regulation, and gene transcription

    Author : Enrique Joffre; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ETEC; diversity; bacterial enterotoxins; polymorphism; gene regulation; gene transcription; Diarrhoeal disease; bacterial infection;

    Abstract : Infection with enterotoxigenic Escherichia coli (ETEC) is a leading cause of diarrhea in children in developing countries and travelers to endemic regions. ETEC is a diverse pathogen, with a wide range of virulence factors including enterotoxins and more than 25 identified colonization factors (CFs). READ MORE
