Development of a live vaccine for gut health in poultry. Development of a live vaccine for gut health in poultry. The project aims to develop a live vaccine against necrotic enteritis, a disease of poultry estimated to cost the global poultry industry $5-6 billion USD/annum. It builds on work that has demonstrated the efficacy of an experimental vaccine. The proven antigen, NetB, will be expressed in live delivery vehicles, including the apicomplexan parasite Eimeria and several bacteria strains ....Development of a live vaccine for gut health in poultry. Development of a live vaccine for gut health in poultry. The project aims to develop a live vaccine against necrotic enteritis, a disease of poultry estimated to cost the global poultry industry $5-6 billion USD/annum. It builds on work that has demonstrated the efficacy of an experimental vaccine. The proven antigen, NetB, will be expressed in live delivery vehicles, including the apicomplexan parasite Eimeria and several bacteria strains particularly suited to use in chickens. Comparative analysis of the different vaccine vehicles will allow evaluation of the relative advantages and disadvantage of the different vehicles for delivery of heterologous vaccine antigens, thus informing the choice of appropriate vectors for this and other vaccine applications.Read moreRead less
STRUCTURAL CHARACTERIZATION OF ACTIVE CONSTITUENTS IN PLANT EXTRACTS WITH POTENTIAL FOR THE CONTROL OF OVINE LICE AND PARASITIC WORMS. The control of lice and parasitic worms are two of the major problems currently confronting the Australian sheep industry. Several plant extracts utilized in traditional medicine have shown a remarkable efficacy in the control of these pests in humans. This project will investigate the sheep lousicidal and anthelmintic activity of a number of plants, and identif ....STRUCTURAL CHARACTERIZATION OF ACTIVE CONSTITUENTS IN PLANT EXTRACTS WITH POTENTIAL FOR THE CONTROL OF OVINE LICE AND PARASITIC WORMS. The control of lice and parasitic worms are two of the major problems currently confronting the Australian sheep industry. Several plant extracts utilized in traditional medicine have shown a remarkable efficacy in the control of these pests in humans. This project will investigate the sheep lousicidal and anthelmintic activity of a number of plants, and identify and chemically characterize the active constituents. This research will lead to the production of more environmentally friendly pest control methods and overcome problems of insecticidal resistance currently facing the industry.Read moreRead less
Towards the development of a novel live vaccine for the control of Glässer's disease (Haemophilus parasuis), a globally significant respiratory disease of swine. Respiratory diseases are common in intensively housed pigs, costing the Australian industry millions of dollars in lost production annually. Glässer's is a highly contagious and often fatal respiratory disease of pigs. Antibiotic therapy is expensive and often results in the emergence of antibiotic resistant organisms. There is also a t ....Towards the development of a novel live vaccine for the control of Glässer's disease (Haemophilus parasuis), a globally significant respiratory disease of swine. Respiratory diseases are common in intensively housed pigs, costing the Australian industry millions of dollars in lost production annually. Glässer's is a highly contagious and often fatal respiratory disease of pigs. Antibiotic therapy is expensive and often results in the emergence of antibiotic resistant organisms. There is also a trend to move away from the use of antibiotics in food production animals. Current vaccines are based on inactivated preparations and do not offer a high level of immune protection. Therefore, there is a great need worldwide for a live vaccine for the effective control of Glässer's disease.Read moreRead less
Reducing the health & economic burden of Campylobacter using a live vaccine. The aim of the project is to develop a vaccine to reduce Campylobacter bacteria in chickens. Campylobacters cause disease in both poultry and humans. Poultry products are the most common source of human infections. By reducing Campylobacter in poultry, the transfer to humans will be reduced. The expected outcomes arising from this work will be a reduction of the economic burden of poultry losses, in an Australian indust ....Reducing the health & economic burden of Campylobacter using a live vaccine. The aim of the project is to develop a vaccine to reduce Campylobacter bacteria in chickens. Campylobacters cause disease in both poultry and humans. Poultry products are the most common source of human infections. By reducing Campylobacter in poultry, the transfer to humans will be reduced. The expected outcomes arising from this work will be a reduction of the economic burden of poultry losses, in an Australian industry valued at $2.8 billion/year, and an improvement in food safety, thus helping to reduce the burden of foodborne illness, estimated to be $1.2 billion dollars/year. This project is, therefore, poised to benefit the Australian economy, specifically primary producers and the general public, by targeted vaccination of poultry.Read moreRead less
