Abstract


Diphyllobothriosis, an infection caused by an adult parasite of the genus Dibothriocephalus, is associated with the intake of raw or undercooked fish. This disease is worldwide in distribution and present sporadic outbreaks. A few cases of Dibothriocephalus infections have been reported in Brazil. This report aims at presenting the case of a male patient from Southern Brazil (Rio Grande do Sul) who was suffering from chronic diarrhea, tested positive for fecal occult blood and upon anamnesis reported eating sushi recently. A parasitological stool test was conducted using the spontaneous sedimentation technique and the microscopic analysis revealed the presence of typical structures of Dibothriocephalus latus. Due to the association between the consumption of raw fish such as salmon and diphyllobothriosis, it is extremely important to consider this infection among the symptomatic population who eats raw or undercooked fishes.
