Se procesan "a ciegas" 511 muestras de heces por las técnicas de Kato-Katz, Willis, Ritchie y directo. Al comparar los resultados obtenidos en el diagnóstico de Trichuris trichiura, Necator americanus y Ascaris lumbricoides, vimos que la de Kato-Katz fué más sensible, revelando el mayor número de casos, siguiéndole en orden sucesivo, el Willis, el Ritchie, y el examen directo. Si se tiene en cuenta que el método de Kato-Katz es además cuantitativo, podemos recomendar-lo como técnica de elección para el diagnóstico de las geohelmintiasis intestinales. Five hundred and eleven samples of feces were examined by several coproparasilological techniques: Kalo-Katz, Willis, Ritchie and direct wet mount. It was found that Kato-Katz was the most reliable technique for the diagnosis of Trichuris trichiura, Necator americanus, and Ascaris lumbricoides, demonstrating the largest number of cases. Willis, Ritchie and direct wet mount were effective in that order. Taking into account that Kato-Katz is a quantitative method, it should be recommended in the diagnosis of soil-transmitted helminthiasis.
