The Type IX Secretion System present in diverse bacteria of veterinary, agricultural, environmental and industrial importance enables effector proteins to be secreted and attached to the cell surface where they contribute to disease pathogenesis or degrade biopolymers of commercial interest. This project aims to determine the structure and assembly mechanism of this complex secretion nanomachine comprising 15 different proteins using state of the art microscopy. Knowledge of the structure will greatly enhance our understanding of secretion mechanisms and our ability to both inhibit the system to treat disease in animals or manipulate the system for industrial applications providing future economic and environmental benefits to our nation.Read moreRead less
Defining the molecular basis for Salmonella persistence. Salmonella infections in animals and humans place significant burdens on the agri-food and healthcare sectors. All mammals and avian species can become chronically infected with Salmonella and such chronic carriage is a reservoir for disease and outbreaks in other animals and humans. Significant gaps in our understanding of Salmonella infection remain, including the molecular mechanisms involved in establishing a chronic carrier state. We ....Defining the molecular basis for Salmonella persistence. Salmonella infections in animals and humans place significant burdens on the agri-food and healthcare sectors. All mammals and avian species can become chronically infected with Salmonella and such chronic carriage is a reservoir for disease and outbreaks in other animals and humans. Significant gaps in our understanding of Salmonella infection remain, including the molecular mechanisms involved in establishing a chronic carrier state. We identified several Salmonella specific genes and subsequent murine studies revealed that a Salmonella mutant lacking these genes is attenuated in mice and especially in the gallbladder. In this project we seek to understand the molecular basis for attenuation and the contribution of each protein to diseaseRead moreRead less

The project is expected to define the epidemiology of C. difficile infection in Australian horses, characterise the genetic and phenotypic traits of C. difficile strains causing equine disease and develop a new tool for enhanced genomic tracking of C. difficile in animals. These outcomes will support strategies by the veterinary sector to improve the detection, prevention and control of C. difficile infections in animals, providing long-term socio-economic benefits arising from reduced incidence and mortality associated with C. difficile infections in Australian horses and livestock.Read moreRead less

Worm infections are a serious disease problem in free-range chicken production systems which now dominate egg production in Australia. This project aims to improve the control of worm infections of chickens by developing new tools for poultry researchers, advisors and farmers to use for this purpose. The project expects to develop novel methods for laboratory-based anthelmintic drug resistance testing, maintenance of defined worm strains and diagnosis of infection. It will also determine the effectiveness of mass treatment in the field and the prevalence of anthelmintic resistance. Use of these tools and information will improve worm control and thus the productivity and welfare of free-range chickens in Australia and worldwide.Read moreRead less
Artificial intelligence to explore and combat eukaryotic pathogens. The revolution in artificial intelligence (AI) provides unprecedented opportunities for integrative analyses of complex multi-omics data sets and for creating radically new strategies to control some of the world’s most serious animal diseases.

The revolution in artificial intelligence (AI) provides unprecedented opportunities for integrative analyses of complex multi-omics data sets and for creating radically new strategies to control some of the world’s most serious animal diseases. In a strong partnership with international experts, we will use AI-based methods to make major conceptual advances in our understanding of eukaryotic pathogens and host-pathogen interactions, discover the "choke-points" in biological pathways, and develop novel treatments, vaccines and diagnostics. This leap forward will substantially enhance the global profile of pathogen research in Australia, build major capacity in a priority area, and enable access to international research funding and networks.Read moreRead less

Overuse of antimicrobials is a driver of antimicrobial resistance. This project aims to address the overuse of antimicrobials in animals by implementing antimicrobial stewardship in veterinary practices and developing methods of antimicrobial use surveillance. It is the first comprehensive study to address and assess inappropriate use of antimicrobials in veterinary medicine- and is expected to improve quality use of antimicrobials by veterinarians and prolong the efficacy of antimicrobials in veterinary medicine. This presents a critical step in reducing community exposure to antimicrobial resistance.Read moreRead less
Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between ....Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between PPID and metabolic syndrome, to generate new insights into the cause and consequences of both diseases. As an added benefit, the project will assist horseracing laboratories to improve their detection methods for peptide doping in younger competition horses.
