- anesthetic overdose
- a congenital portosystemic shunt
- hypoglycemia
- congenital renal amyloidosis

- Neuromuscular disease may be causing the signs in this dog.
- Gastric neoplasia may be causing the signs in this dog.
- A positive-contrast barium radiographic series of the stomach and intestines should next be performed.
- A complete blood count and serum chemistry should next be performed.
- Abdominal ultrasonography should next be performed.
- What is the most common congenital cardiac disorder in horses?
- patent ductus arteriosus

- Definitive antemortem diagnosis of Johne’s disease in cattle can be based upon:
- positive reaction to intravenous johnin
- positive reaction to intradermal johnin
- positive agar gel immunodiffusion test
- positive serum neutralization test
- recovery of the causative organism from culture of feces or ileocecal lymph node
- At the time of an acute outbreak of transmissible gastro-enteritis, sows that are due to farrow within 2 wk should be:
- vaccinated with a gene-deleted, modified live-virus vaccine orally and intraperitoneally
- moved to an isolated farrowing area
- exposed to live virus through feeding of intestines from affected piglets
- induced to farrow and piglets treated with antiserum at birth
- vaccinated with a gene-deleted, killed-virus vaccine orally and intramammarily
- Any of the following conditions may be associated with cyanotic mucous membranes except:
- right-to-left shunting congenital cardiac defect
- sepsis
- methemoglobinemia
- hypoventilation

- Influenza A virus:
