Bovine Aspergillosis Produced by the Inoculation of Conidiospores of Aspergillus fumigatus into a Mesenteric or Jugular Vein.

Conidiospores of Aspergillus fumigatus were inoculated during the second trimester of pregnancy into a mesenteric vein of 14 heifers and into a jugular vein of three additional heifers. Heifers were killed at intervals after inoculation. Lesions were confined largely to the placentas, livers, and lungs.
