Abstract: 

Acute disseminated aspergillosis caused by Aspergillus fumigatus is reported in a 4-year-old cow given broad spectrum antibiotics and anti-inflammatory therapy. All stomach compartments were infected and hyphal invasion of gastric blood vessels was the probable source of generalization to the liver, lung and kidneys. Throughout the Peyer's patches of the jejunum there were acute necrotic foci with Aspergillus hyphae and similar foci occurred in the corresponding mesenteric lymph nodes. This points to the Peyer's patches being a portal of entry for A. fumigatus to the lymphatic system of the intestine.
