A deceased 10-year-old male ostrich was diagnosed with severe
necrotizing enteritis and septicemia. The bird was inappetent for 3
weeks and had neurologic signs 2 days prior to death. Macroscopically,
no significant lesions were noted aside from congestion of the liver,
kidneys, and spleen. Histopathology revealed severe fibrinonecrotic
enteritis associated with large numbers of gram-negative bacteria,
multifocal fibrinoid necrosis in portal arteries, accumulation of fibrin
in hepatic sinusoids, myocardial degeneration, and necrosis. There was
also squamous metaplasia in the glands of the esophagus and external
ears. A gramnegative rod was isolated in pure culture from intestine,
liver, lungs, and trachea and identified as an Aeromonas species. The
concentration of vitamin A in the liver was extremely low. The lesions
seen in the intestine and liver and the isolation of an Aeromonas
species from various tissues strongly suggest that this bacterium was
the cause of the necrotizing enteritis, septicemia, and death of this
ostrich. Vitamin A deficiency might have predisposed the bird to the
Aeromonas infection. 2009;53:310-316. |
