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.

Antibiotic Resistance And Multiple Antibiotic Resistance In Human Commensal Escherichia Coli In Australia
Funder
National Health and Medical Research Council
Funding Amount
$509,202.00
Summary
Antibiotic resistance, particularly resistance to all or nearly all of the antibiotics available for treatment is now very common and impacts heavily on the treatment of bacterial infections. This project will track resistance genes in reservoirs where antibiotic resistance genes may be present in high concentrations as these are a likely source of the resistance genes in disease-causing bacteria. One such reservoir, the bacteria in the intestines of healthy humans will be examined.
Delineation Of The Role Of RasGRP4 In Mast Cell Growth, Differentiation And Activation, Using RasGRP4 Deficient Mice
Funder

Funding Amount
$636,199.00
Summary
Mast cells are important in immunity. Mast cells have been implicated in asthma and more recently they have been shown to participate in immunity against bacteria, viruses and fungi. We have identified a specific protein, RasGRP4, which is restricted to mast cells and plays an important role in their development and function. Understanding this molecule more extensively will give us a much better understanding of diseases that the mast cell is involved in such as asthma and other disorders.
The Role Of Protein Oxidation And Isomerization Pathways In The Pathogenesis Of Neisseria Meningitidis
Funder
National Health and Medical Research Council
Funding Amount
$264,816.00
Summary
Neisseria meningitidis causes meningococcal disease. It lives on the surface of the nasopharynx and in certain circumstances, can invade into the bloodstream causing sepsis. This is a complicated process, which involves many proteins produced by the bacteria. Many of these proteins contain a special covalent bond, the disulphide bond, which allows them to function properly. We are investigating how these disulphide bonds are put into proteins.
Development Of Innovative Approaches To Manage Insect-transmitted Diseases
Funder
National Health and Medical Research Council
Funding Amount
$4,435,142.00
Summary
This program grant focuses on the development of new methods to control mosquito-borne diseases, including those caused by dengue, Japanese encephalitis, and chikungunya viruses. We are investigating whether the introduction of Wolbachia micro-organisms into mosquitoes can be used to selectively eliminate old mosquitoes and reduce transmission of human pathogens. We will also determine whether Wolbachia have any non-lethal affects on mosquito behaviours such as dispersal and biting activity whic ....This program grant focuses on the development of new methods to control mosquito-borne diseases, including those caused by dengue, Japanese encephalitis, and chikungunya viruses. We are investigating whether the introduction of Wolbachia micro-organisms into mosquitoes can be used to selectively eliminate old mosquitoes and reduce transmission of human pathogens. We will also determine whether Wolbachia have any non-lethal affects on mosquito behaviours such as dispersal and biting activity which determine the level of contact between mosquitoes and humans.Read moreRead less
PH-dependent, Antibody-mediated Enhancement Of Genital Chlamydial Infection: Implications For Vaccine Design ?
Funder
National Health and Medical Research Council
Funding Amount
$373,228.00
Summary
Antibody found in cervicovaginal secretions is predominantly of the IgG subclass. In the acidic environment of the female reproductive tract IgG antibodies against surface antigens on Chlamydia may actually enhance rather than prevent infection, due to uptake of IgG-coated bacteria by the neonatal Fc receptor (FcRn), which is found on the surface of epithelial cells in the reproductive tract. The proposed studies will determine the effects of chlamydial antibodies on the course of infection.
