Funded Activity Summary

Leptospirosis is a significant cause of death in tropical regions of the world. Recent outbreaks in Nicaragua and Brazil are timely reminders of the seriousness of disease caused by the Leptospira bacteria. In these outbreaks >10% of people developing the disease did not recover. Spread of the disease does not occur from person to person, but rather from animal to human. Leptospira are shed from infected animals via the urine; human infection may occur through contact with infected urine or urine contaminated materials. In Australia, leptospirosis is an occupational hazard with dairy farmers, pig handlers, banana pickers and abattoir workers being those most at risk. A recent and alarming development is the emergence of new risk groups associated with certain leisure activities. For example, in the USA three triathletes died from leptospirosis and it was subsequently determined that the source of infection was contaminated swimming water. This project will investigate aspects of the development of disease and immunity during infection by Leptospira. This will be achieved by analysing the set of proteins located on the surface of the bacterium. These proteins play a key role in the development of disease. Using state of the art technology, each of the proteins will be purified and identified. This will enable experiments that will enhance our understanding of the development of disease at a molecular level.
