Characterization of the Intestinal Corynosoma stru-mosum (Phylum: Acanthocephala) from the Harbor Seal, Phoca largha, from the East Sea, Korea

초록

An acanthocephalan parasite, Corynosoma strumosum, was found in the intestine of harbor seal, Phoca largha, living in the East Sea, Korea. The probosci’s hook and trunk spine patterns typical of the collected worms indicat-ed it to be C. strumosum. The body lengths measured are 4.2-5.8 (4.9) mm in males and 5.3-6.8 (5.7) mm in females. The proboscis is bent ventrally, armed with 18 longitudinal rows of 9-13 hooks in males and 20 longitudinal rows of 11-13 hooks in females. The proboscis receptacle is double-walled with the robust trapezoidal neck being unarmed. The hind-trunk is pipe-shaped with posterior parallel sides. The characteristic hind trunk spines cover the anterior third of the ventral surface. The lemnisci are equal and slightly shorter than the dou-ble-walled proboscis receptacle, which is longer than the proboscis. This species is an acanthocephalan parasite reported for the first time in Korea. © The Korean Society of Veterinary Clinics.
