| Abstract: | Eosinophilic enteritis (EOE) is a type of inflammatory bowel disease and is characterized
clinically by chronic obstinate diarrhea. Three Japanese Black (JB) fattening cattle (2
males and 1 female) on different cattle farms presented with chronic episodic diarrhea
without fever or dehydration. Soft reddish spherical carneous tissues (1−3 cm) were
occasionally excreted within the diarrheic feces. Administration of antibiotics,
antidiarrheal drugs and vermicides had no therapeutic effect, but dexamethasone improved
the fecal characteristics. The symptoms persisted until the animals were slaughtered at
27–30 months of age. Histopathological examination of the intestines revealed marked
eosinophilic infiltration in the lamina propria and submucosa. From these findings, we
diagnosed these cattle as the first cases of EOE in JB cattle. |
