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.

Summary
SARS-CoV-2-induced dead cell fragments drive viral uptake and inflammation. This project will apply advanced cell biology and imaging techniques to investigate how macrophages, which lacks a canonical receptor for viral entry, become infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and elicit inflammatory responses. Its insights into a novel pathway of viral entry is expected to advance our understanding of host-pathogen interaction. The project is intended to uncover t ....SARS-CoV-2-induced dead cell fragments drive viral uptake and inflammation. This project will apply advanced cell biology and imaging techniques to investigate how macrophages, which lacks a canonical receptor for viral entry, become infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and elicit inflammatory responses. Its insights into a novel pathway of viral entry is expected to advance our understanding of host-pathogen interaction. The project is intended to uncover the role of SARS-CoV-2-induced dead cell fragmentation in promoting viral uptake and inflammation. Its findings should provide significant scientific, health and economic benefits by informing new research directions on infection and innate immunity as well as future therapeutic designs for infection treatment.Read moreRead less
How do apicomplexan parasites steal amino acids from their hosts? The single-celled parasites that cause malaria and toxoplasmosis are adept at stealing nutrients from the host animals that they infect. How they do this is, however, poorly understood. This project seeks to identify the processes by which these parasites scavenge amino acids, an essential class of nutrient, from their hosts. Using innovative experimental approaches, the project aims to identify and characterise the parasite prote ....How do apicomplexan parasites steal amino acids from their hosts? The single-celled parasites that cause malaria and toxoplasmosis are adept at stealing nutrients from the host animals that they infect. How they do this is, however, poorly understood. This project seeks to identify the processes by which these parasites scavenge amino acids, an essential class of nutrient, from their hosts. Using innovative experimental approaches, the project aims to identify and characterise the parasite proteins that mediate the uptake of different amino acids into the parasite. The intended outcomes of the project are to provide comprehensive insights into a fundamental aspect of parasite biology, and inform strategies to treat the diseases caused by these parasites by cutting off their nutrient supply.Read moreRead less
Unlocking bacterial shapeshifting and its role in antimicrobial resistance. This project aims to combine advanced imaging with innovative microfluidics to identify how microbial shapeshifting can be exploited as a target for new antimicrobials. Infections that are hard to treat due to increasing antimicrobial resistance not only have an enormous, global impact on mammalian health, including livestock and humans, but also carry a growing economic burden. Advanced understanding of microbial life c ....Unlocking bacterial shapeshifting and its role in antimicrobial resistance. This project aims to combine advanced imaging with innovative microfluidics to identify how microbial shapeshifting can be exploited as a target for new antimicrobials. Infections that are hard to treat due to increasing antimicrobial resistance not only have an enormous, global impact on mammalian health, including livestock and humans, but also carry a growing economic burden. Advanced understanding of microbial life can propel urgently needed progress this area. Specifically, the project outcomes are expected to aid the development of next generation antibiotics. The new fundamental knowledge should also benefit translational prevention, identification and management efforts of a rising national and global health threat.Read moreRead less
