Combined adenovirus and rotavirus enteritis with Escherichia coli septicemia in an emu chick (Dromaius novaehollandiae).
A 2-week-old emu chick (Dromaius novaehollandiae) of approximately 200 g body weight was presented for necropsy with a history of weakness, diarrhea, pallor of the head, and acute death. Hemorrhagic enteritis with mild hepatomegaly was noted on gross examination. Microscopic examination revealed necrohemorrhagic enteritis with intralesional intranuclear basophilic viral inclusion bodies in intestinal epithelial cells; splenic lymphoid necrosis and fibrin exudation; hepatocellular vacuolar change; and multiple clusters of small gram-negative bacilli in the liver, spleen, yolk sac, and intestine. Transmission electron microscopy of negatively stained fecal specimens and thin sections of small intestine revealed clusters of viral particles consistent with adenovirus and rotavirus. Attempts at viral isolation from pooled tissue specimens were unsuccessful. Escherichia coli was isolated from specimens of liver and intestine and from an abdominal swab.
