Animal parasitology & immunogenetics lab

We are the Animal Parasitology & Immunogenetics Lab (API) and are based at the AgriBio Centre for AgriBioscience at La Trobe University, Bundoora.

Our group is led by Professor Mike Stear, who has over 40 years of experience in parasite research. The major aim of the group is to understand host-parasite interactions in animals, and to use this understanding to improve methods of parasite control.

Of particular interest to our group are roundworms, the most-costly animal health condition in Australian livestock. In Victoria, the major parasite effecting sheep flocks is the brown stomach worm. This parasite is rapidly developing drench resistance, therefore better methods of control need to be developed.

Research areas

  • Breeding sheep and cattle for resistance to disease
  • Immunity to parasitic infections
  • The role of eosinophils in host resistance to parasites
  • The role of the MHC in resistance to roundworm infections
