Epizootic Bovine Abortion.

Epizootic Bovine Abortion.
Epizootic bovine abortion, or Foothill Abortion, appears to be geographically limited to the western United States. Live fetuses may be aborted, and most dead fetuses are fresh. Fetal lesions include granulomatous hepatitis, which is generally periportal, and central veins are dilated.
