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

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

There is an urgent need for new antiparasitics to treat multi-drug resistant livestock infections. This project aims to explore the bacteria and fungi present in the microbiomes of heavily infected sheep faeces and pastures, challenging them with environmental cues, including those from associated parasites, to stimulate production of defensive chemicals hidden deep within their genomes. Enabled by an integrated pipeline of high throughput analytical cultivation, molecular networking, and chemical and biological analyses, expected outcomes include an enhanced ability to explore and exploit valuable chemistry hidden within microbial genomes, leading to the discovery of new classes of natural antiparasitic to safeguard livestock.
