Urinary tract infections (UTI) are among the most common infectious diseases of humans and a major cause of morbidity and mortality. In the USA, UTI accounts for >$1.6 billion in medical expenses each year. It is estimated that 50% of women will develop a UTI in their lifetime. This research aims to understand the processes by which bacteria colonize the human bladder. The work has implications for the development of new approaches to prevent and treat UTI.

The Molecular Physiology Of Streptococcus Pneumoniae During Sepsis

Summary
The project will determine the way in which pneumococcus changes its properties when it invades the bloodstream of the human host. Since these changes are linked to sepsis then this new understanding will provide information that can be used to manage and control acute pneumococcal infection.

Summary
Bacterial infectious diseases are a serious threat to human health, accounting for over 10 million deaths each year. This multidisciplinary collaborative team is investigating the complex interactions between major disease-causing bacteria and their human hosts, in order to determine how they cause disease. These studies will make a major contribution to fundamental knowledge in this field. This information is also essential for the development of cheaper and more effective vaccines, as well as ....Bacterial infectious diseases are a serious threat to human health, accounting for over 10 million deaths each year.

Summary
The bacterium Pseudomonas aeruginosa causes a number of serious diseases of humans particularly of immunocompromised patients. We have found that this bacterium secretes enzymes that have the ability to digest DNA. This proposal aims to work out how this bacterium uses these enzymes to infect human tissues and escape killing by immune cells. The results from this study will help to determine if these proteins may be used as targets for the development of new anti-infective drugs.
Some of the world's most important diseases, including important diseases of indigenous chilren and the hospitalised elderly are caused by bacteria that carry a surface coating called a capsule. It is not clear how this capsule is retained by bacteria. Resolution of this question could lead to the development of new disinfectants that will stop hospital-acquired infections, to new reagents that can be incoporated into medical devices where bacteria frequently grow, and new antibiotics.
Diseases caused by the pneumococcus represent the largest cause of vaccine preventable death in the world today, mainly pneumonia and meningitis. In 2011, 16 developing countries will introduce pneumococcal conjugate vaccines, none in east Asia. Lack of research has been a major barrier to their use in the region. We have established an international centre of excellence in the field and we seek support to extend the capacity of this group and to transfer the technology to Vietnam.
Understanding The Biosynthesis Of Complex Polyketide Lipid Toxins In Pathogenic Mycobacteria

Summary
Some major infectious diseases such as tuberculosis are caused by bacteria that make very unusual lipids (fats) that can kill human cells or interfere with the human immune system. The aim of this project is to work out how bacteria make these lipids. This knowledge will open up new avenues for treatments to stop bacterial lipid production and prevent disease. There are also potential applications in harnessing the bacterial lipid machinery to make new drugs and a wide range of other chemicals.

Summary
We have established a mouse model that has been genetically modified and cannot produce the cytokine tumour necrosis factor. This cytokine is secreted in the beginning of the inflammatory response. If these mice are infected with a parasite they are not able to heal the infection and die quickly. We can demonstrate that these mice cannot regulate the beginning inflammatory response and do not form a cellular infiltrate at the site of infection.
