Summary
Unlocking the helminth ‘early infection gap’ using 3D cell culture models. This project aims to revolutionise the study of critical early host-parasite interactions using innovative 3D cell culture models, reducing our dependence on animal infections. Liver fluke is the most economically important zoonotic parasite of Australian livestock and is a significant contributor to global food insecurity. Due to the reliance of parasites on mammalian hosts to survive, very little is known about the earl ....Unlocking the helminth ‘early infection gap’ using 3D cell culture models. This project aims to revolutionise the study of critical early host-parasite interactions using innovative 3D cell culture models, reducing our dependence on animal infections. Liver fluke is the most economically important zoonotic parasite of Australian livestock and is a significant contributor to global food insecurity. Due to the reliance of parasites on mammalian hosts to survive, very little is known about the early infection process. Expected outcomes include new knowledge on key migratory stimuli and liver fluke biology. Benefits include the identification of drug targets and vaccine candidates for use in livestock via the development of animal-free in vitro screening platforms that will serve as a prototype for other parasites.Read moreRead less
How do kangaroo herpesviruses jump to new host species? . This project aims to study alphaherpesviruses of kangaroos and other marsupials. These viruses cause outbreaks of severe disease in captive populations of marsupials when they are transmitted from natural hosts to new host species, but these cross-species transmission events are poorly understood. This project aims to study these viruses, and their capacity for cross-species transmission, using new approaches that consider herpesviruses a ....How do kangaroo herpesviruses jump to new host species? . This project aims to study alphaherpesviruses of kangaroos and other marsupials. These viruses cause outbreaks of severe disease in captive populations of marsupials when they are transmitted from natural hosts to new host species, but these cross-species transmission events are poorly understood. This project aims to study these viruses, and their capacity for cross-species transmission, using new approaches that consider herpesviruses as dynamic, mixed populations of viruses. This project also aims to develop novel, practical, and accessible vaccines to prevent disease. Benefits are expected to arise through prevention of disease in captive marsupial populations, including benefits for conservation efforts and for Australian tourism.

A next-generation whole parasite bovine Babesia vaccine. . In Australia, Babesia parasites cause most of the severe and often fatal cases of cattle-tick fever, a globally significant tick-borne disease. It can be prevented by a live-attenuated parasite vaccine which has critical limitations of a 4-day shelf-life and risk of severe disease if administered to adult cattle. This project aims to evaluate in cattle a novel whole parasite Babesia bovis vaccine that cannot cause disease and can be pres ....A next-generation whole parasite bovine Babesia vaccine. . In Australia, Babesia parasites cause most of the severe and often fatal cases of cattle-tick fever, a globally significant tick-borne disease. It can be prevented by a live-attenuated parasite vaccine which has critical limitations of a 4-day shelf-life and risk of severe disease if administered to adult cattle. This project aims to evaluate in cattle a novel whole parasite Babesia bovis vaccine that cannot cause disease and can be preserved as an off-the-shelf product without losing efficacy. The expected outcome is a significantly improved vaccine for a major infectious disease that affects primary food production. As the disease imposes a major economic burden, it will have great benefit for the Australian livestock industry.
