Abstract

LA INVENCION SE REFIERE A UN METODO PARA CONCENTRAR ORGANISMOS PATOGENOS TRANSPORTADOS POR AGUA POTENCIALMENTE CONTAMINADA POR DENSIDADES DILUIDAS DE DICHOS ORGANISMOS. EL AGUA POTENCIALMENTE CONTAMINADA SE DIRIGE A LO LARGO DE UNA VIA DE FLUJO ALARGADA (34) QUE QUEDA DENTRO DE UN PLANO PERPENDICULAR A UN EJE DE ROTACION, Y SE SOMETE A FUERZAS CENTRIFUGAS, MEDIANTE ROTACION DE DICHA VIA DE FLUJO ALREDEDOR DEL EJE ROTACIONAL. DICHO METODO SE PUEDE LLEVAR A CABO UTILIZANDO UNA CENTRIFUGA DE PLASMAFERESIS SANGUINEA DE TIPO CANAL DE FLUJO CONTINUO (30). DICHO METODO SE HA ENSAYADO RESPECTO A SU CAPACIDAD PARA RECUPERAR PARASITOS PROTOZOARIOS COMO CRYPTOSPORIDIUM Y GIARDA A PARTIR DE AGUA CONTAMINADA, HABIENDOSE OBSERVADO TASAS DE RECUPERACION DE HASTA EL 100 %.
