Distribution of Sparganum mansoni in 7 species of terrestrial snakes in Wonju City was surveyed. All kinds of snakes were found to be served as intermediate hosts of this larval worm except Elaphe schrenkii which has already been recorded as important host. Authors believe that Zamenis spinalis was firstly recorded as intermediate host of Sparganum mansoni in Korea.

Some aspects of infection status, host-parasite relations and sources of human infection were briefly discussed.


Fig. 1: A section through mass of free stage of Sparganum mansoni (×30). Thin encapsulation with meager inflammatory response.

Fig. 2: The conglomerated masses of S. mansoni on the subcutaneous tissue of Agkistrodon halys.

Fig. 3: Section through encapsulated stage (×30). Viable worm is still present within wall and thick fibrous encapsulation is infiltrated by lymphocytes.

Fig. 4: Encapsulated stage of S. mansoni in subcutaneous tissue of Dinodon rufozonatum.

Fig. 5: Section through degenerative stage (×30). Amorphous eosinophilic material is filled within the granulomatous encapsulation.

Fig. 6: Elevated portion of snake muscle suggests the hidden intramuscular infection.
