Applied and molecular immunology, animal disease
Professor Frank Griffin is the Director of the Ag@Otago research theme at the University of Otago, a new initiative drawing on the strengths in plant and animal production, food and health, and sustainability. With over 40 years experience in the Department of Microbiology and Immunology he is a consultant to many international committees and consortia, and a member of societies of immunology and microbiology in New Zealand, Australia and the United States.
The focus of Ag@Otago is:
Professor Frank Griffin was the founding director of DRL, which has been carrying out research on mycobacterial diseases (tuberculosis/paratuberculosis) in ruminants and wildlife species for the past 35 years. In the past decade their work has led to the development of improved immunodiagnostics and molecular techniques for the detection of paratuberculosis (Johnes disease). DRL has recently identified deer breeds with polarised phenotypes for resistance and susceptibility to paratuberculosis.
DRL is now a part of Otago Innovation Limited.
DRL research is currently focused on exploring immune mechanisms that are associated with either pathological (diagnostic) or protective responses in deer exposed to M.paratuberculosis. Purebred lines of deer that display extremes of resistance or susceptibility to paratuberculosis are being studied to identify candidate genes that result in a resistant (R) or susceptable (S) phenotype In vivo and in vitro. Transcriptomics on mononuclear cells studies on deer with either R or S genotypes are being carried out currently.
Objectives of current studies
Characterise pathways of immunepathogenesis in experimentally infected deer displaying different stages of Johne's disease
Identify immune markers associated with protective immunity in animals with resistant genotypes.
Map genes associated with resistance or susceptable deer phenotypes.
These projects have involved collaboration with researchers at AgResearch (Invermay and Wallaceville). Important key relationships have been formed with the end users who are supporting these programmes with co-funding and access to unique deer breeds. Government support is through the Foundation for Research Science and Technology (FoRST) and the Johnes Disease Research Consortium (JDRC).
