Investigating the role of wildlife and wild canids in
transmission of Neospora caninum
Neosporosis is an important emerging protozoal reproductive
disease of cattle worldwide that is considered to involve a
canine-bovine life cycle. In eastern Australia, outbreaks occur on
dairy and beef cattle properties, particularly in coastal regions
and often associated with proximity to bushland.
Wild canids have been suggested as a source of infection.
However data to support the hypothesis that wild canids are the
source of infection is lacking and a possible role of foxes in
bovine neosporosis needs investigation.
A research group has been formed which included the two
investigators that initiated bovine neosporosis research in
Australia, plus expertise in wild canid and fox ecology. I am
improving the diagnostic tests for Neosporosis, managing the
collection of samples of faeces, blood and tissues from foxes and
wild dogs during routine culling; and conducting prevalence
surveys, relating collection points to habitat and using GIS to
determine the spatial epidemiology of Neosporosis and develop
models to assist management of neosporosis.
Isolation and transmission studies on N caninum in wild
dogs and foxes will form part of my project.
