RESUMO
The effecto of El Niño/ENSO on terrestrial atmosphere appears to be extremelly clear. However there are outstanding evidences showing its effect on humans and their activities. In fact, prevalence of some parasitic infections have increased during El Niño phenomenon. The reasons for that are the migrations of sylvatic mammals, fishes and birds as well as by environmental contamination. In this report, we show evidence respect of new cases of human infection by Diphyllobothrium pacificum clearly associated with a cyclic manifestation of El Niño in the Chilean Pacific coast during 1975-2000

La diphyllobothriosis constituye una zoonosis relacionada con el consumo de carnes crudas o insuficientemente cocida de peces de agua dulce o mar. Se presenta un caso de diphyllobothriosis por Diphyllobothrium pacificum diagnosticado en Antofagasta en un niño de tres años, residente permanente en esta ciudad-puerto del Norte de Chile. El paciente eliminó espontáneamente una estróbila de 55 cm, a partir de la cual se realizó estudio morfométrico de proglótidas y huevos, concluyéndose que se trataba de un ejemplar de D. pacificum. Se administró tratamiento con praziquantel sin que se eliminaran nuevos ejemplares ni huevos, como tampoco se presentó anemia. Se investigó al grupo familiar constituido por cuatro personas sin encontrar otros infectados. Se destaca que los 16 casos de diphyllobothriosis por D. pacificum documentados en Chile, tres corresponden a niños entre 7 y 3 años

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
