Infection with the plerocercoid or sparganum of a pseudophyllidean tapeworm, usually in a dermal sore resulting from application of infected flesh as a poultice; infection may also occur from ingestion of uncooked frog, snake, mammal, or bird intermediate or transport host bearing the spargana, but not from fish with Diphyllobothrium larvae, inasmuch as sparganosis is an infection with nonhuman pseudophyllidean tapeworms, usually species of Spirometra. Sparganosis may also develop from ingestion of water containing procercoid-infected Cyclops.
sparganosis/spar·ga·no·sis/ (spahr″gah-no´sis) infection with the larvae (spargana) of any of several species of tapeworms, which invade the subcutaneous tissues, causing inflammation and fibrosis.
Etymology: Gk, sparganon, swaddling clothes, osis, condition
an infection with larvae of the fish tapeworm of the pseudogenus Sparganum, recently identified as the plerocercoid stage of Diphyllobothrium. It is characterized by painful subcutaneous swellings or swelling and destruction of the eye. It is acquired by ingesting larvae in contaminated water or in inadequately cooked infected frog flesh. Treatment includes surgery and local injection of ethyl alcohol to kill the larvae.
