sparganosis

...The important second intermediate hosts in Japan are cherry salmon, pink salmon, rainbow trout, and salmon. Humans become infected by ingesting the plerocercoids when eating raw fish, which then develop into adults in the small intestine. However, when the plerocercoids of D. mansoni , which is also a member of the same order of phyllostachys and whose definitive hosts are dogs and cats (snakes, frogs, chickens, etc.), are ingested, the larvae do not develop into adults, but move around the body as larvae and cause sparganosis, which causes tumors in various places under the skin. The order Cestoda includes important human parasites such as the Taeniidae family's Taenia, Taenia, Taenia, and Taenia, as well as the Hymenocoele family's Taenia, Taenia, and Taenia. It also includes the Hymenocoele family's Taenia, Taenia, and Taenia, and the Dipylidium caninum family's Taenia.
