Abstract
A 4-year-old female Barbary sheep (Ammotragus lervia) was found dead in the Gwangju Uchi Park Zoo. The animal had previously exhibited weakness and lethargy, but no signs of diarrhea. The carcass was emaciated upon presentation. The main gross lesion was characterized by severe serous atrophy of the fat tissues of the coronary and left ventricular grooves, resulting in the transformation of the fat to a gelatinous material. The rumen was fully distended with food, while the abomasum evidenced mucosal corrugation with slight congestion. Microscopic examination revealed the presence of Balantidium coli trophozoites within the lymphatic ducts of the gastric lymph node and the abdominal submucosa. On rare occasions, these organisms may invade extra-intestinal organs, in this case the gastric lymph nodes and abomasum.
