1. Outer membrane proteins of Yersinia pestis : Ail and OmpA
Abstract : A vast number of studies have been completed on the virulence determinants of Yersinia spp.; however, the focus of many of these studies has been on the virulence plasmid and the plasmid-encoded Type three secretion system. Nevertheless, many chromosomal genes whose products are directly involved in virulence have also been identified. READ MORE

2. Periodontitis in adolescents : presence of Aggregatibacter species and interactions with the host
Abstract : Aggregatibacter actinomycetemcomitans and Aggregatibacter aphrophilus are closely related gram-negative bacteria mainly found in the oral cavity. Periodontitis in adolescents is associated with the presence of A. actinomycetemcomitans, but not with the presence of A. aphrophilus. READ MORE

3. Gene fusion in protein engineering : design of novel peptides and bifunctional enzymes
Abstract : The gene fusion technique is widely used in protein engineering and in this thesis it constitutes the basis of both the construction of artificial bifunctional enzymes and the display of two novel peptides. Artificial bifunctional enzymes have been used as model systems in the studies of native multifunctional enzymes and proximity effects within these complexes. READ MORE

4. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs
Abstract : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. READ MORE

5. Molecular detection of Vibrio cholerae and protozoa from water and interaction of V. cholerae clinical isolates with Acanthamoeba castellanii
Abstract : Microbial contamination of water is a major public concern due to outbreaks of cholera, giardiasis and cryptosporidiosis. Despite this, a large number of bacteria, protozoa and viruses can be found in water. READ MORE
