  2. 16. Bacterial antibody hydrolyzing enzymes – as bacterial virulence factors and biotechnological tools

    Author : Eleni Bratanis; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunoglobulins; Immunomodulation; Antibody mediated immunity; Glycosylation; Bacterial virulence; Bacterial enzymes; Biotechnology; streptococcus pyogenes; Bdellovibrio bacteriovorus;

    Abstract : Antibodies are an essential part of the human immune system, and antibody mediated immunity has been an area of interest for many researchers for almost a century. An accumulation of knowledge regarding antibody structure, glycosylation and receptor interactions has contributed to the current understanding of antibody mediated immunity. READ MORE

  4. 17. The Colonization Strategies of Nontypeable Haemophilus influenzae - Bacterial Colonization Factors and Vaccine Development

    Author : Farshid Jalalvand; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ABC-transporter; bacterial colonization; Haemophilus influenzae; Haemophilus Protein F; laminin; NTHi; pathogenesis; vaccine; virulence; vitronectin.;

    Abstract : Nontypeable Haemophilus influenzae (NTHi) is a remarkably proficient colonizer of the human respiratory tract. The aim of this thesis has been to characterize currently known, and identify novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity.

    Abstract : Antibiotic resistances are one of the biggest threats to global health and if we don’t change our behavior and way of using antibiotics we will end up in a ‘post-antibiotic era’, in which common infections and minor injuries can once kill again and up to 10 million deaths per year may occur by 2050. Therefore, there is a high need for new anti-bacterial drugs, especially of alternatives to existing antibiotics with already described resistances. READ MORE

  7. 20. 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
