Fifteen new human cases of diphyllobothriasis in Chile are reported, one of them a multiple case of infection by Diphyllobothrium latum. Five scolices and 28 m of strobila were recovered after treatment with Niclosamide in a male adult patient with multiple infection. In other 5 cases, after treatment, only one worm was recovered in each person and all corresponded to D. latum species; worms measured between 2.9 to 11.0m. In 9 cases, only the eggs of parasites were reported in the coprological exam. Thirteen cases were determined in the lakes area from south of Chile where infection by plerocercoids in salmonids is very frequent and the persons consume smoked and raw ("cebiche") fishes.
