[Nasal, pulmonary, and abomasal aspergillosis (Aspergillus fumigatus) in a calf].

This study presents a case of nasal aspergillosis in a 17-days old calf (German Fleckvieh): it had been admitted moribund to the Clinic for Ruminants of the University of Munich, and died after a short time. Pathologically, the calf was diagnosed with purulent-necrotizing rhinitis, necrotizing pneumonia, and diphtheroid-necrotizing abomasitis. Histologically, fungal elements were found in all the localizations mentioned before, and mycologically, Aspergillus fumigatus was cultured from nasal cavity. Pathogenesis is discussed.
