The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Defining the antiviral effects of Wolbachia in Aedes aegypti mosquitoes. Mosquitoes that carry a bacterium called Wolbachia do not transmit human pathogenic viruses. These mosquitoes are being developed as a biocontrol tool to prevent mosquito-borne diseases. This project aims to define the molecular basis for virus inhibition by Wolbachia. Using unique biological tools including mosquitoes carrying different strains of Wolbachia that do or do not inhibit dengue virus, the project will define ho ....Defining the antiviral effects of Wolbachia in Aedes aegypti mosquitoes. Mosquitoes that carry a bacterium called Wolbachia do not transmit human pathogenic viruses. These mosquitoes are being developed as a biocontrol tool to prevent mosquito-borne diseases. This project aims to define the molecular basis for virus inhibition by Wolbachia. Using unique biological tools including mosquitoes carrying different strains of Wolbachia that do or do not inhibit dengue virus, the project will define how Wolbachia modifies its host to create an antiviral state. The findings will provide insight into how viral pathogens can be suppressed in insect hosts. This may guide future viral disease intervention strategies for diverse areas afflicted by insect-borne viral disease, including human health and agriculture.Read moreRead less

Summary
How ecology shapes the viromes of wild birds. This project will reveal the host factors associated with the diversity, evolution and dynamics of viruses using state-of-the-art metatranscriptomics in Australian wild birds. The structure of virus communities and their associated ecological drivers in wild animal hosts remain a black-box, even though they are the largest source of viral diversity in nature. This project expects to generate key insights into host-associated drivers of viral communit ....How ecology shapes the viromes of wild birds. This project will reveal the host factors associated with the diversity, evolution and dynamics of viruses using state-of-the-art metatranscriptomics in Australian wild birds. The structure of virus communities and their associated ecological drivers in wild animal hosts remain a black-box, even though they are the largest source of viral diversity in nature. This project expects to generate key insights into host-associated drivers of viral community dynamics and the subsequent effect of anthropogenic factors such as urbanisation and poultry production. Identifying host factors that affect viral ecology in wild birds will constitute a cornerstone in understanding the emergence of virulent viruses and/or their spread to poultry or humansRead moreRead less
