Adem\u00e1s, se comprob\u00f3 un 5,3% y un 9,8% de prevalencia en perros de los distritos de Ri\u00f1ihue y Malihue, respectivamente, pero no se observ\u00f3 infecci\u00f3n en gatos y cerdos. Los par\u00e1sitos recuperados despu\u00e9s del tratamiento fueron identificados como Diphyllobothrium latum. La infecci\u00f3n humana por D. latum en los distritos afectados se favorece por el consumo de peces ahumados o sometidos a cocci\u00f3n insuficiente. La investigaci\u00f3n de 1450 peces (4 especies introducidas y 11 aut\u00f3ctonas) capturados entre 1986-1987 en la cuenca del r\u00edo Valdivia, demostr\u00f3 la existencia de plerocercoides de D. latum y\/o Diphyllobothrium dendriticum en Salmo gairdneri y Salmo trutta, entre los peces introducidos, y en algunas especies aut\u00f3ctonas. La prevalencia e intensidad media en las infecciones de los peces as\u00ed como el grado de agregaci\u00f3n de las infrapoblaciones var\u00eda en los distintos sectores. Algunas especies de peces actuar\u00edan como hu\u00e9sped intermediario y otras como hu\u00e9spedes parat\u00e9nicos de Diphyllobothrium spp. en la cuenca del r\u00edo Valdivia. Como medidas de control para la difilobotriasis en los distritos afectados se propone un mejoramiento de las condiciones de saneamiento b\u00e1sico, educaci\u00f3n sanitaria y tratamiento de las personas infectadas.<\/jats:p>","DOI":"10.1590\/s0034-89101989000100007","type":"journal-article","created":{"date-parts":[[2005,4,27]],"date-time":"2005-04-27T14:05:18Z","timestamp":1114610718000},"page":"45-57","source":"Crossref","is-referenced-by-count":18,"title":["Epidemiolog\u00eda de la difilobotriasis en la cuenca del r\u00edo Valdivia, Chile"],"prefix":"10.1590","volume":"23","author":[{"given":"Patricio","family":"Torres","sequence":"first","affiliation":[{"name":"Universidad Austral de Chile, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ren\u00e9","family":"Franjola","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"P\u00e9rez","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sadi","family":"Auad","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Uherek","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan C.","family":"Miranda","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luisa","family":"Flores","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Riquelme","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel","family":"Salazar","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Hermosilla","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rub\u00e9n","family":"Rojo","sequence":"additional","affiliation":[{"name":"Universidad Austral de Chile, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","first-page":"45","article-title":"Studies of the helminth fauna of Norway.
