SR Print(0) ID 1193138018 T1 Noninvasive Cestode Infections T2 Current Medical Diagnosis & Treatment 2023 YR 2023 FD 2023 PB McGraw-Hill Education PP New York, NY SN 9781264687343 LK accessmedicine.mhmedical.com/content.aspx?aid=1193138018 RD 2024/04/19 AB The four major tapeworms that cause noninvasive infections in humans are the beef tapeworm Taenia saginata, the pork tapeworm Taenia solium, the fish tapeworm Diphyllobothrium latum, each of which can reach many meters in length, and the dwarf tapeworm Hymenolepis nana. Taenia and Hymenolepis species are broadly distributed, especially in the tropics; D latum is most prevalent in temperate regions. Other tapeworms that can cause noninvasive human disease include the rodent tapeworm Hymenolepis diminuta, the dog tapeworm Dipylidium caninum, and other Taenia and Diphyllobothrium species. Invasive tapeworm infections, including T solium (when infective eggs, rather than cysticerci are ingested) and Echinococcus species, will be discussed separately.
