title: A Case of Chaunocephalosis byChaunocephalus ferox(Digenea: Echinostomatidae) in an Oriental White Stork,Ciconia boyciana, in Korea.
abstract: We intended to describe a case of chaunocephalosis and morphological characteristics of its causative agent,Chaunocephalus ferox, recovered from an oriental white stork,Ciconia boyciana, in the Republic of Korea. An oriental white stork was referred to the Wildlife Center of Chungbuk in Korea in February 2014 for severe depression with cachexia and it died the next day. At necropsy, the stomach was severely expanded and 7 thick-walled nodules were observed in the upper part of the intestine. Although the stomach was filled with full of foreign materials, the intestine was almost empty. The nodules were globular and total 9 flukes were recovered. They were 8,030-8,091 μm in length and 3,318-3,333 μm in maximum width. Because the flukes had bulbous forebody with short narrow subcylindrical hindbody, 27 collar spines, and vitelline follicles not reaching to the posterior end, the specimens were identified as beingC. ferox. The cyst formation induced thickening of the intestinal wall with narrowing of the lumen that could have contributed to the gastric impaction to the death of the host. This is the first described case of chaunocephalosis and its causative agentC. feroxfound from an oriental white stork in Korea.
