Sure, the bird (a male) had marked endothelial hyperplasia and
intracytoplasmic granular parasitic cysts confined mainly to the
endothelium of arteioles in the brain and pecten although occasional cysts
were found in the kidney and lungs. Initial tests were positive for
Toxoplasma antigen (done at WA Dept. Agriculture), although repeat tests
performed by the US Dept of Agriculture indicated that the agent was not
Toxo but probably a new Theilerian parasite. We have since seen more than
a dozen similar cases (all female) in Kestrels from the Geraldton region.
It is an interesting disease, I only wish I had the resources to
investigate it further.
