  1. 1. A Molecular Approach for Investigation of the Prevalence and Neurotoxin Formation of Clostridium botulinum in Food Safety Assessment

    Author : Maria Lövenklev; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neurotoxin gene expression; neurotoxin; food safety assessment; food preservation; Clostridium botulinum; enrichment PCR; Food and drink technology; qRT-PCR; Livsmedelsteknik; prevalence;

    Abstract : In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategies for food preservation and risk assessment.

  2. 2. Structural and functional studies of a novel Botulinum neurotoxin and of MTH1

    Author : Linda Henriksson; Pål Stenmark; Maria Selmer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Botulinum neurotoxin; botulism; cancer; gene cluster; molecular structures; MTH1; NTNH; oxidised nucleotides; progenitor complex; protein expression; protein purification; X-ray crystallography; Biochemistry; biokemi;

    Abstract : X-ray crystallography visualizes the three dimensional molecular structures of proteins at atomic resolution. Seeing the molecular structure of a biomedically interesting protein enables a higher understanding of its function. READ MORE

  3. 3. Structural Insights into Botulinum Neurotoxins and the ALFA-tag System : Structural and Functional Studies of Proteins Related to the Botulinum Neurotoxins and Design of a Novel Epitope Tag

    Author : Markel Martínez-Carranza; Pål Stenmark; Thomas Binz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; botulinum neurotoxin; Biochemistry; biokemi;

    Abstract : This thesis is divided into two sections; the first part describes our work in the field of botulinum neurotoxins (presented in papers I, II, III, and manuscript IV) and the second part summarizes our work involving the design of a new biochemical tool (presented in paper V).Botulinum neurotoxins (BoNTs) produced by the anaerobic bacterium Clostridium botulinum are the most poisonous substances known to date.

  4. 4. Real-time PCR for diagnosis of botulism and quantification of neurotoxin gene expression in Clostridium botulinum

    Author : Ingrid Artin; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; detection; qRT-PCR; Clostridium botulinum; molecular methods;

    Abstract : The objectives of the work presented in this thesis have been to develop molecular methods for (i) detection of Clostridium botulinum in food and clinical samples, and (ii) monitoring the expression of the neurotoxin gene, cnt, during different growth phases and under different growth conditions. For the diagnosis of botulism, a real-time PCR-based method including an internal amplification control for C. READ MORE

  5. 5. Structural and functional studies of proteins of medical relevance : Protein-ligand complexes in cancer and novel structural folds in bacteria

    Author : Robert Gustafsson; Pål Stenmark; Pavlína Řezáčová; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray crystallography; Cancer; MTH1; oxidised nucleotides; MTHFD2; nucleotide metabolism; one-carbon metabolism; Botulism; Botulinum neurotoxin; OrfX; OrfX gene cluster; Biochemistry; biokemi;

    Abstract : X-ray crystallography is a tool for determining the structures of proteins and protein-ligand complexes. In this thesis the method has been employed to study several proteins of medical relevance.Cancer is a terrible disease, severely impacting those affected, as well as their family and friends.
