ABSTRACT
A difilobotríase é uma moléstia intestinal provocada por cestódeos do gênero Diphyllobothrium (tênia) que até pouco tempo havia poucos relatos em nosso país. Porém, em decorrência do aumento do consumo de peixes crus, mal cozidos ou defumados e da falta de cuidado nos seus preparos, vêm sendo identificados casos autóctones no Brasil. O número de pessoas parasitadas pelo platelminto difilobotríase, presente em várias regiões do mundo, vem aumentando desde 2003. A doença pode ser assintomática ou causar desconforto abdominal e interferir na absorção da vitamina B12, podendo causar anemia megaloblástica. Abster-se do consumo de pescado cru, defumado em temperaturas inadequadas ou mal cozido é a principal medida para a sua prevenção.
The intestinal diphyllobotriasis is a disease caused by Diphyllobothrium (cestodes of the genus Taenia [tapeworm]) that until recently had a few reports in our country. However, as a result of increased consumption of raw fish, soft-boiled or smoked and lack of care in their staging have been identified indigenous cases in Brazil. The number of people by the flatworm diphyllobotriasis parasitized, present in various regions of the world, comes increasing since 2003. The disease may be asymptomatic or cause abdominal discomfort and interferes in the absorption of vitamin B12, leading to megaloblastic anemia. Avoid from eating raw, smoked or soft-boiled fish is the primaries beware of their prevention.

Between may and july 1994, 17 adult returning salmons, oncorhynchus kisutch, were collected in the River Simpson, Chile. All fishes showed infection by plerocercoids of diphyllobothrium sp. in different locations: stomach, spleen, liver, mesenteries and gonads. Infection with larval cestodes of an unidentified species of phillobothriidae was determined in the intestine of seven (41,2 percent) salmons and its prevalences of infection showed significant differences between female and male salmons. The 94,4 percent of total plerocercoids of diphyllobothrium were isolated from the stomach wall. Prevalence and mean intensity of infection by diphyllobothrium sp. did not show significant differences between fishes of different sex

We report a 26 years old asymptomatic female that expelled spontaneously a 39 proglottid strobila. The taxonomic study of proglottids and eggs found in the stool examination concluded that the patient was infected by Diphyllobothrium pacificum. This infection was probably acquired by the ingestion of raw fish (Sciaena deliciosa) with lemon in a traditional plate called "cebiche". She was treated with a single dose of praziquantel in a dose of 10 mg/kg body weight. After 24 h of treatment there were no scolices on feces. The patient did not have anemia. All eight family members studied, did no have the infection. A follow up stool examination three months later remained negative
