[Outbreak of paraventricular and ventricular mucormycosis in fattening bulls].
There is a description of mass occurrence of nine cases of acute, fatal paraventricular and ventricular mucormycosis in fattened bulls at the age of about 18 months. In the reticulum, the disease was characterized by numerous ulcerations penetrating into the submucosa. In rumen the deposits were of hemorrhagic character penetrating through a thick muscular layer into the subserosa. Hemorrhagic peritonitis was within the range of those changes. Thromboses of arteries and veins prevailed in the microscopic picture. Inflammatory reparative changes were formed by neutrophile leucocytes. Mucoraceum fibres were demonstrated in pathological manifestations. In three cases, strains of Rhizopus cohnii and Absidia ramosa were cultivated simultaneously from the sub-ulcerous layers in the reticulum. A number of findings testify that the mass occurrence of mucormycosis followed the feeding of mouldy bakery wastes on the basis of acidosis.
