Virulence determinants influencing re-emergence of a complex RNA virus. This project intends to examine the effects that specific genes in naturally occurring recombinants have on their capacity to cause disease and spread between chickens. Coronaviruses are major pathogens of domestic animals throughout the world.

This project intends to examine the effects that specific genes in naturally occurring recombinants have on their capacity to cause disease and spread between chickens. Coronaviruses are major pathogens of domestic animals throughout the world. Recurrent re-emergence of the coronavirus of chickens, infectious bronchitis virus, has been associated with recombination between wild type viruses and vaccine viruses, but the factors influencing this, and in particular the selective advantages genes from vaccine viruses confer on these recombinants, are unknown. The ultimate aim of the project is to identify both novel vaccines and alternative management strategies that might reduce the frequency of re-emergence of this virus and other coronaviruses.Read moreRead less
Harnessing innate immunity to mitigate bovine respiratory disease. Bovine Respiratory Disease (BRD) is the most significant health problem faced by the beef industry worldwide, causing economic losses of up to $40 million annually in Australia alone. This Project aims to assess an immunostimulant for its ability to induce resistance to infection with bovine respiratory viruses associated with BRD. The Project is expected to generate fundamental new knowledge in veterinary virology. Expected outc ....Harnessing innate immunity to mitigate bovine respiratory disease. Bovine Respiratory Disease (BRD) is the most significant health problem faced by the beef industry worldwide, causing economic losses of up to $40 million annually in Australia alone. This Project aims to assess an immunostimulant for its ability to induce resistance to infection with bovine respiratory viruses associated with BRD. The Project is expected to generate fundamental new knowledge in veterinary virology. Expected outcomes include scholarly publications. The Project will provide significant benefits, such as advances to fundamental knowledge, training of higher research degree students and proof-of-concept data to promote collaborations with commercial partners to develop novel treatment strategies to limit BRD.Read moreRead less
