Difilobotriosis humana: Un caso en área no endémica de la Argentina / Human diphyllobothriosis: A case in a non-endemic area of Argentina

La difilobotriosis es una parasitosis intestinal causada por la infección de cestodos del genero Diphyllobothrium. En la Argentina, la Patagonia Andina es considerada una zona endémica para esta parasitosis. La infección por Diphyllobothrium latum no ha sido previamente notificada en la provincia de Mendoza; en este trabajo comunicamos un caso de esta parasitosis que fue confirmada por el análisis de las características morfológicas de los huevos eliminados con la materia fecal de un paciente infectado. Se destaca la necesidad de información y capacitación de los profesionales de la salud en el diagnóstico y tratamiento de parasitosis no endémicas.

Diphyllobothriosis is an intestinal parasitosis caused by cestodes infection of the genus Diphyllobothrium. In Argentina, the Andean Patagonia is considered an endemic area for this parasitosis. Diphyllobothrium latum infection has not been previously reported in the province of Mendoza, Argentina. We are now reporting then the first case. Diphyllobothriosis was confirmed by examination of morphologic characteristics of the eggs eliminated in the patients' feces. These results suggest the requirement of a more specific training of health workers in the diagnosis and treatment of non endemic parasitosis. We want to emphasize the need of health workers' education on diagnosis and treatment of endemic and non-endemic parasitosis.

Infección por helmintos parásitos en salmón coho, oncorhynchus kisutch, durante su retorno al río Simpson, Chile / Infection by parasitic helmiths in coho sallmon, oncorhynchus kisutch, during their return to Simpson river, Chile

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
