knabe,
We see Coxiella burnetti placentitis/abortion in goats through the lab here, with some regularity.
I see an occasional case in cattle - all in dairy cattle, to date. Had a case submitted earlier this week, from a dairy herd that's experienced 4 early 3rd trimester abortions in the last week or so; placenta was PCR-positive for Coxiella; will be examining histologic sections next week - veterinarian did not request histopathology, but I fixed a piece, just in case...
