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.
