Em nosso estudo, realizamos pesquisa de ant\u00edgenos de E. histolytica em amostras fecais de pacientes residentes na cidade de Bel\u00e9m, Par\u00e1, Brasil, utilizando ensaio imunoenzim\u00e1tico (E. histolytica Test, TechLab Inc., Blacksburg, Estados Unidos) dispon\u00edvel comercialmente. Foram analisadas 845 amostras, com positividade em 248 (29,35%). A infec\u00e7\u00e3o por E. histolytica foi maior no grupo et\u00e1rio acima de 14 anos (30,36%) que no grupo de 0-14 anos (28,28%), por\u00e9m sem signific\u00e2ncia estat\u00edstica (p &lt; 0,05). Do total de amostras analisadas, 334 foram tamb\u00e9m investigadas por m\u00e9todos parasitol\u00f3gicos (direto, Hoffman e Faust et al.). Houve discord\u00e2ncia nos resultados dos m\u00e9todos ELISA e coprosc\u00f3pico em 83 amostras (24,85%), com maior n\u00famero de positivos no teste imunoenzim\u00e1tico.
