1. Botulinum neurotoxins
Abstract : Botulinum neurotoxins (BoNTs) are the most potent toxins known to man, with less than 1 μg of pure toxin being enough to kill an adult man. Despite the high toxicity, BoNTs are widely used in cosmetics and in medicine for the treatment of an increasing number of medical conditions. READ MORE

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

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

4. 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
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.

5. Genomic organization and diversity of Clostridium botulinum group III : the bug behind animal botulism
Abstract : Botulism is caused by botulinum neurotoxins (BoNTs) produced by the spore forming strictly anaerobic bacterium Clostridium botulinum. Seven different types of BoNTs (type A-F) have so far been established on the basis of neutralization with different antibodies. READ MORE
