The genus Spirometra is a group of medical tapeworms that have been neglected for a long time.Its plerocercoid larvae can parasitize different tissues and organs in humans,causing a food/water-borne parasitic zoonosis known as sparganosis.The classification system of Spirometra was controversial for a extended period of time,causing confusion for related scientific research and teaching.In this paper,we provided a systematic review of systematic changes and taxonomic research progress of Spirometra tapeworms,to find appropriate answers to relevant questions and lay foundation for the study of related species.
