Brief description The rapid emergence and spread of antibiotic resistance in bacteria that cause infectious diseases is of major concern to public health authorities throughout the world. Many of the genes that are responsible for this resistance are carried on mobile genetic elements, which are discrete segments of genetic material that can move from one bacterium to another. These genetic elements are important vehicles for the transmission of virulence and antibiotic resistance genes in most bacteria. This project is centred on bacteria that cause intestinal diseases and have the potential to transfer genetic information to other bacteria that are present in the intestine. The focus will be on elucidating the mechanism of action of an enzyme encoded by two of these genetic elements. This enzyme is responsible for the movement of these elements from one site in the bacterial genome to another, by a process that is being increasingly recognised as important in antibiotic-resistant disease-causing bacteria. The project will employ the latest tools of molecular biology to determine the function of this enzyme, and its associated genetic elements, at the detailed molecular level. These studies will contribute to our understanding of how these antibiotic resistance elements are transferred within and between different bacterial cells. In the longer term the project will contribute towards the development of improved methods for the control and treatment of infectious diseases.
