          Resumen Se compararon 4 métodos coproparasitológicos para determinar la prevalencia de Strongyloides stercoralis. Se analizaron 100 muestras fecales de individuos con edades comprendidas entre 1 y 50 años, de la comunidad de San Juan de Macarapana, municipio Sucre, estado Sucre, Venezuela; encontrándose una prevalencia del 24%, correspondiente al diagnóstico por el cultivo de heces en placas de agar, mientras que por el método directo, el método de Ritchie modificado y el método de Baermann modificado se detectó la presencia de Strongyloides stercoralis en un 13, 5 y 16% de las muestras, respectivamente. El grupo etario más afectado fue el de los niños menores de 10 años (83,33%), de los cuales el 80% pertenecían al sexo masculino. En conclusión, el cultivo de heces en placas de agar fue el más sensible para el diagnóstico de Strongyloides stercoralis, y permitió clasificar a San Juan de Macarapana como un área hiperendémica (>5%) de estrongiloidiasis.

          Abstract A comparative study of four coproparasitologic methods to determine Strongyloides stercoralis prevalence was carried out. One hundred faecal samples from individuals between 1 and 50 years old from the village of San Juan de Macarapana, Sucre municipality, Sucre state, Venezuela were analyzed. A prevalence of Strongyloides stercoralis was found in 24% of feces cultured in agar plates, whereas using the direct method, the modified Ritchie method and the modified Baermann method this parasite was detected in 13%, 5% and 16% of samples, respectively. The age group most affected were children under 10 years old (83,33%), of which 80% were male. In conclusion, the most sensitive method for the diagnosis of S. stercoralis was feces culture in agar plates. This method allowed us to classify San Juan de Macarapana as an hiperendemic area (>5%) for strongyloidiasis.

              Strongyloidiasis and other intestinal nematode infections.

              In contrast to other helminthic parasites, Strongyloides stercoralis can replicate within humans, causing a chronic persistent infection that can be severe and fatal in compromised hosts. This article reviews new developments to help meet the clinical challenges of this infection, including clinical clues to the diagnosis, new diagnostic methods, including stool culture and serological assays, new drugs such as albendazole and ivermectin, and difficult treatment issues. The other major intestinal nematode parasites, including Ascaris, hookworm, and Trichuris, are extremely common worldwide, but in North America their clinical presentation is often more subtly related to low-grade worm burdens or allergic manifestations. Special consideration is given to difficult management issues, including the patient with unexplained eosinophilia, the pregnant patient, and the patient who passes a worm.
