Abstract: Intestinal parasites infect a large parcel of the world population and are prevalent in poor communities. In indigenous communities, the environment is highly favourable to the spread of these parasitic agents due to poor sanitation, unhealthy eating habits, lack of personal hygiene among other factors. Objective: perform an investigation about the incidence of parasites in three communities of the Potiguar ethnic group located in the city of Baía da Traição, Province of Paraíba, Brazil. Methods: the raw material consisted by 109 feces samples from people of Coqueirinho, São Miguel and Forte communities.
