Novel vaccines and serotyping scheme for Haemophilus parasuis. Glasser's disease, caused by the bacterium Haemophilus parasuis, is a significant problem in Australian and overseas pig industries. Current approaches to the management of Glassers disease utilise antibacterials and also vaccines. However, antibacterials are of limited effectiveness in juvenile pigs (weaners) that are difficult to medicate other than by injection, and current vaccines are only protective against the serotypes incl ....Novel vaccines and serotyping scheme for Haemophilus parasuis. Glasser's disease, caused by the bacterium Haemophilus parasuis, is a significant problem in Australian and overseas pig industries. Current approaches to the management of Glassers disease utilise antibacterials and also vaccines. However, antibacterials are of limited effectiveness in juvenile pigs (weaners) that are difficult to medicate other than by injection, and current vaccines are only protective against the serotypes included in the vaccine. We propose to examine the immune response to natural infection and identify potential vaccine candidates which will then be tested in vaccine trials. The APAI will focus on developing a DNA-based typing scheme for H. parasuis.Read moreRead less

Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase ge ....Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase gene and encapsulate them, creating bioreactors secreting chitinases. Therapeutic effects will be tested by grafting bioreactors to mice inoculated with Aspergillus. The research is a new approach to fighting chitin containing pathogens, with potential applications from parasite infestations in livestock to fungal infections in humans.Read moreRead less
Flea Control by Immunological Intervention. Fleas are bloodsucking parasites that are the major cause of skin disease in pets. Currently, all available flea products rely upon chemical control and many have active components that have real or perceived health problems. Given that insect growth regulators do not kill adult fleas and pet owners are interested in using alternatives to insecticides, there is a clear need for a complementary form of flea control. We describe the novel use of Prote ....Flea Control by Immunological Intervention. Fleas are bloodsucking parasites that are the major cause of skin disease in pets. Currently, all available flea products rely upon chemical control and many have active components that have real or perceived health problems. Given that insect growth regulators do not kill adult fleas and pet owners are interested in using alternatives to insecticides, there is a clear need for a complementary form of flea control. We describe the novel use of Proteomic technology to identify flea proteins that are "switched on" during feeding and are specifically located in the gut. This project will enable the development of a vaccine that is systemic, kills adult fleas, is long-lasting and residue-free.Read moreRead less

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
