The development and evaluation of a new therapy for the prevention and treatment of bacterial infections in hospitals. The technology used in this project will enable products to be developed from the Australian dairy industry which may safely provide protection and treatment for diarrhoea acquired in hospitals for which there are few effective options. The product will be cost effective and can be used as a public health tool to control outbreaks in those most susceptible to severe disease.
Vaccination of poultry infected with multiple Salmonella serovars. Salmonella is a zoonotic, foodborne pathogen found on eggs and poultry meat. It is the second largest cause of human gastrointestinal disease, thus, reduction of Salmonella on poultry farms is paramount to public health. This project aims to evaluate the long-term efficacy of a commercial Salmonella Typhimurium vaccine against multiple serotypes, including the emerging Salmonella Enteritidis. This project will generate new knowle ....Vaccination of poultry infected with multiple Salmonella serovars. Salmonella is a zoonotic, foodborne pathogen found on eggs and poultry meat. It is the second largest cause of human gastrointestinal disease, thus, reduction of Salmonella on poultry farms is paramount to public health. This project aims to evaluate the long-term efficacy of a commercial Salmonella Typhimurium vaccine against multiple serotypes, including the emerging Salmonella Enteritidis. This project will generate new knowledge in avian immunology using an innovative approach to evaluate the host response to multi-serovar infection. Outcomes of this project will future proof the Australian poultry industry against exotic Salmonella serotypes benefitting the industry by significantly reducing risks of future outbreaks and economic loss.Read moreRead less
Molecular characterisation of antibiotic resistance genes in Salmonella enterica and Escherichia coli recovered from food-producing animals and humans. Antibiotic resistance is an accelerating global problem. Antibiotic resistance genes are located on mobile genetic elements which can be horizontally transferred between distantly related bacteria. It is becoming increasingly apparent that healthy humans carry populations of resistant bacteria as part of the normal microbial flora. This project w ....Molecular characterisation of antibiotic resistance genes in Salmonella enterica and Escherichia coli recovered from food-producing animals and humans. Antibiotic resistance is an accelerating global problem. Antibiotic resistance genes are located on mobile genetic elements which can be horizontally transferred between distantly related bacteria. It is becoming increasingly apparent that healthy humans carry populations of resistant bacteria as part of the normal microbial flora. This project will characterise the antibiotic resistance gene arrangements among populations of bacteria which belong to the Enterobacteriaceae. These resistant bacteria represent a threat to human and veterinary health because they are readily ingested as part of the food chain and represent reservoirs for the spread of antibiotic resistance genes to pathogens.Read moreRead less
A single vaccine for influenza and pneumonia. Influenza and bacterial pneumonia collaborate to kill millions of people each year. This project aims to develop a single vaccine that will provide long-lasting protection against both influenza and pneumonia.
Development of molecular markers for resistance to blackleg disease (Leptosphaeria maculans) in canola. Canola (Brassica napus) is a valuable oil seed crop grown in many parts of the world and contributes annually $A450 million to the Australian economy. The overall aim of this project is to develop molecular markers for blackleg resistance using Australian germplasm along with evaluation in Australian disease nurseries which are regarded worlwide to develop the highest levels of disease pressu ....Development of molecular markers for resistance to blackleg disease (Leptosphaeria maculans) in canola. Canola (Brassica napus) is a valuable oil seed crop grown in many parts of the world and contributes annually $A450 million to the Australian economy. The overall aim of this project is to develop molecular markers for blackleg resistance using Australian germplasm along with evaluation in Australian disease nurseries which are regarded worlwide to develop the highest levels of disease pressure. Once molecular marker systems are developed and evaluated, they will be applied to facilitate the selection of Nugrain's (Industry Partner) canola breeding programs. Any molecular markers and QTL developed for Australian cultivars would find commercial application in breeding programmes.Read moreRead less
Investigating the Ability of Honey to Inhibit Bacterial Biofilms Found in Chronic Wounds. Chronic (non-healing) wounds are a serious health problem in Australia. One quarter of our institutionalized aged population have pressure ulcers. The difficulty in treating these wounds is that most contain communities of bacteria, called biofilms, that are not killed by conventional antibiotics. Special honeys from Australia and NZ that are effective in chronic wound treatment can eradicate these biofilms ....Investigating the Ability of Honey to Inhibit Bacterial Biofilms Found in Chronic Wounds. Chronic (non-healing) wounds are a serious health problem in Australia. One quarter of our institutionalized aged population have pressure ulcers. The difficulty in treating these wounds is that most contain communities of bacteria, called biofilms, that are not killed by conventional antibiotics. Special honeys from Australia and NZ that are effective in chronic wound treatment can eradicate these biofilms. This project will identify the components in honey that do this and determine how they do it, to provide a more effective chronic wound treatment. It will decrease the prevalence of these wounds in Australia and the associated personal trauma and health costs.Read moreRead less
Defining domains within Mycoplasma hyopneumoniae surface proteins that interact with host extracellular matrix: efficacy testing of candidate vaccines in swine. Over 90% of Australian commercial pig production facilities are affected by Mycoplasma hyopneumoniae, the causative agent of swine enzootic pneumonia. This disease causes economic losses in Australia of over $20 million per annum and up to $1 billion per annum in major swine rearing countries worldwide. This project will determine the p ....Defining domains within Mycoplasma hyopneumoniae surface proteins that interact with host extracellular matrix: efficacy testing of candidate vaccines in swine. Over 90% of Australian commercial pig production facilities are affected by Mycoplasma hyopneumoniae, the causative agent of swine enzootic pneumonia. This disease causes economic losses in Australia of over $20 million per annum and up to $1 billion per annum in major swine rearing countries worldwide. This project will determine the protective efficacy of new generation vaccines against M. hyopneumoniae, which aim to block the colonisation process and prevent disease .Read moreRead less
Identification and characterisation of Mycoplasma hyopneumoniae surface-molecules that interact with the host epithelium. Mycoplasma hyponeumoniae causes porcine enzootic pneumonia, a disease that significantly impacts swine production. Current vaccines are unable to prevent colonisation of the respiratory tract and are costly to produce and administer. The expression of microbial adhesins that mediate adherence to the extracellular matrix is considered the initial step in host colonisation for ....Identification and characterisation of Mycoplasma hyopneumoniae surface-molecules that interact with the host epithelium. Mycoplasma hyponeumoniae causes porcine enzootic pneumonia, a disease that significantly impacts swine production. Current vaccines are unable to prevent colonisation of the respiratory tract and are costly to produce and administer. The expression of microbial adhesins that mediate adherence to the extracellular matrix is considered the initial step in host colonisation for many bacterial pathogens. We propose to identify M. hyopneumoniae cell surface moleculaes that interact with components of the extracellular matrix. Targetting these cell surface molecules will lead to therapeutics that prevent disease and block colonisation, eventually eradicating the host pathogen from pig production facilities.Read moreRead less
Smarter fermentations through starter culture genomics. Australia makes over $1 billion dollars worth of cheese each year, however fermentation can be adversely affected by virus (phage) attack or sub-optimal strain mixtures. The latest genomics and molecular biology approaches will be used to characterise and optimise starter culture strains leading to improved flavour, quality and efficiency in cheese making.
