Abstract
Objective: This work aims to test and compare three coproparasitological techniques for the diagnosis of intestinal parasites in humans. Methods: 141 analyzes of faecal samples from people of varying ages were carried out, using three methodologies: the method of Hoffman, Pons and Janer-adapted by Katagiri S and Oliveira-sequeira TCG (2007), the method of Willis-Mollay (1921) and the technique of Gordon and Whitlock-modified (or OPG). Results: he prevalence of helminthiasis using the Hoffman, Pons and Janer-adapted method was 14.18% (20), for the Willis-Mollay method it was 15.32% (19) and for the OPG technique it was 12 , 94% (15). Conclusion: The results showed that the Willis-Mollay method recovered a greater number of genera of instestinal parasites and proved to be faster and easier to perform. And with the realization of the three methodologies, it can be observed that the species of Ascaris lumbricoides and Trichuris trichiura were the most prevalent in this study.
