Estudio comparativo de recuperación de formas parasitarias por tres diferentes métodos de enriquecimiento coproparasitológico

Abstract

A total of 165 fecal samples were analyzed, using two sedimentation methods: Ritchie (R), Carles Barthelemy (CB), and one of flotation: Willis (W), in order to optimize intestinal parasites diagnosis and to determine the techniques effectiveness. Parasites were found in 119 (72.12%) of those analyzed. Significant differences were in protozoa recovery (p < 0,001), being observed 81.4% (R), 77.4% (CB), and 57.8% (W). Blastocystis hominis, Giardia lamblia, Ascaris lumbricoides and Trichuris trichiura were recovered more frequency by means of sedimentation, being Ritchie's method the most effective one (p < 0.05).
