Diphyllobothrium pacificum human infection. Report of one case

We report a 26 years old asymptomatic female that expelled spontaneously a 39 proglottid strobila. The taxonomic study of proglottids and eggs found i n the stool examination concluded that the patient was infected by Diphyllo bothrium pacificum. This infection was probably acquired by the ingestion o f raw fish (Sciaena deliciosa) with lemon in a traditional plate called "ce biche". 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 remain ed negative.
