Abstract

Systemic aspergillosis were outbroken of 17 Korean native calves at livestock farm in Kyunggi province. Two 3 months old calves were died after having diarrhea, coughing, dyspnea, nasal discharge, and abdominal breathing. These calves were diagnosed of aspergillosis as multifocal to coalescing pyogranulomatous inflammation with intralesional aspergillus infiltration at liver, kidney, spleen, heart, lymph nodes, lungs, intestine and cerebrum. Aspergillus fumigatus was cultured from the affected tissues. And the small intestine was positive against bovine viral diarrhea (BVD) virus on FA test. We considered that the secondary fungal infections killed the calves after BVD virus infection primarily.
