The proposed research is a basic study into molecular mechanisms of interaction of bacteria with host cells and/or survival in the environment, with a potential for the development of novel antibacterial drugs.
Depending on a specific project title (to be discussed with the supervisor) a research could be focused on any relevant area, including investigation of specific virulence traits/factors, study of bacterial interaction with host cells (e.g. adhesins of probiotic strains), peptidases or protein secretion, or investigation of the mechanisms of stress response.
In addition, we’re offering training in bacterial genomics, and so a project could be focused on bacterial genome sequencing using IonTorrent (Personal Genome Sequencing Machine) available here.
Although research in our lab is focused on Campylobacter and Yersinia, we are also interested in probiotics, and also welcome suggestions/proposal to study other bacterial pathogens. Therefore, an example of a possible research outlined below does not exclude other options, and we’re happy to discuss alternative proposals.
Campylobacter is the main bacterial cause of gastroenteritis worldwide. In particular, it is the most common cause of diarrhoea in England and Wales with over 50,000 cases of Campylobacter infection reported annually. Despite implementation of various ways to control this pathogen in poultry, chickens remain the most important source of infection in humans. Colonisation of host tissues is an important step in bacterial infection. One of the mechanisms involved in colonisation is attachment of bacteria to host cells via specific interaction between bacterial adhesins and host cell receptors. In addition, adhesins may be involved in biofilm formation protecting bacteria from adverse environmental conditions.
Investigation of selected known and putative adhesins using in vitro binding assays.
Molecular cloning, PCR, mutagenesis, protein expression and purification, in vitro binding assays, bioinformatics.
