Sparganosis is a parasitic infection caused by the Diphyllobothrium or the plerocercoid larvae of the genus Spirometra including S. mansoni, S. ranarum, S. mansonoides and S. erinacei.[1][2] it was first described by Patrick Manson from China in 1882,[3] and the first human case was reported by Charles Wardell Stiles from Florida in 1908.[4] The infection is transmitted by ingestion of contaminated water, ingestion of a second intermediate host such as a frog or snake, or contact between a second intermediate host and an open wound or mucous membrane.[5][6] Humans are the accidental hosts in the life cycle, while dogs, cats, and other mammals are definitive hosts. Copepods (freshwater crustaceans) are the first intermediate hosts, and various amphibians and reptiles are second intermediate hosts.[7]
