Dr. Leonardo Susta

After earning his veterinary degree, Dr. Susta spent the last 7 years working on high-consequence poultry diseases at the University of Georgia, where he earned his doctorate, and at the Southeast Poultry Research Laboratory (USDA-ARS), where he worked for two and a half years as research associate. Dr. Susta has worked extensively on

molecular characterization and clinico-pathological assessment of Newcastle disease virus (NDV) and avian influenza virus (AIV) isolates in multiple avian species.  Another area of Dr. Susta’s research included production of recombinant NDV clones in order to dissect NDV immunopathogenesis, and to evaluate the use of cytokines to enhance immune response to vaccination. As a board certified veterinary pathologist, Dr. Susta has extensive experience in diagnostic pathology of common poultry species.

At the University of Guelph, and as a member of the Poultry Health Research Network, Dr. Susta is establishing a research program that focuses on multiple infectious diseases of avian species, with particular emphasis for commercial and backyard poultry.  Dr. Susta’s work will include applied research for the development of more effective vaccine strategies, surveillance of important poultry pathogens in Ontario, and validation of next-generation sequencing for quick and reliable full-genome sequencing of important poultry viruses.  Basic research will be conducted to dissect the determinant of resistance avian pathogens, and to investigate quasispecies mutant spectra of avian viruses such as AIV and NDV.
