Epidemiología de la difilobotriasis en la cuenca del río Valdivia, Chile

Abstract: RESUMEN:Entre los meses de marzo y octubre de 1987 fueron examinados 1295 personas de seis distritos ribereños de la cuenca del río Valdivia, determinándose un 1,2% de prevalencia de infección por Diphyllobothrium en los distritos de Riñihue y Las Huellas. Además, se comprobó un 5,3% y un 9,8% de prevalencia en perros de los distritos de Riñihue y Malihue, respectivamente, pero no se observó infección en gatos y cerdos. Los parásitos recuperados después del tratamiento fueron identificados como Diphyllobothriu… Show more

“…5 Results of this study also support the as-sumption that the source of human infections with D. pacificum is sea fish, whereas human-infecting taxa of Diphyllobothrium widely distributed in the northern hemisphere, such as D. latum and D. dendriticum, are transmitted by freshwater fishes. 10,11,13,14 Received February 14, 2006. Accepted for publication April 5, 2006.…”

“…Despite the fact that D. pacificum was differentiated from other Diphyllobothrium species by a number of morphological characters, 4,5,8 the validity and identity of this species found in humans was questioned because other species of the genus, such as D. latum and D. dendriticum, have been reported from fish and humans on the Pacific Coast of South America and in Brazil. 2,5,[9][10][11][12][13][14][15] Therefore, a comparative study of several species of Diphyllobothrium and related genus Spirometra was carried out. Their phylogenetic relationships were assessed on the basis of the ITS2 gene sequences.…”

“…Two of those infections are caused by the nematodes Anisakis simplex and Pseudoterranova decipiens, and the other two are produced by the cestodes Diphyllobothrium latum and Diphyllobothrium pacificum. Except for D. latum which infects salmonids and authocthonous fish introduced into sweetwater 16 , other parasites are transmitted to man by his eating sea fish 9,15,17 . Human infections produced by larval stages of P. decipiens are commonly named anisakiasis in the broad sense 5 , codworm anisakiasis 12 or Pseudoterranovosis according to standardized nomenclature of animal parasitic diseases 6 .…”

“…Los casos de difilobotriasis detectados son independientes del sexo y de la edad de los hospedadores, como ocurre en otros países donde también se ha presentado esta parasitosis 1,5,7,16,20,35,37,38,41 . Los 2 antihelmínticos más utilizados (niclosamida y praziquantel) son los recomendados actualmente para eliminar este parásito por su efectividad y ausencia de contraindicaciones.…”
