RESUMO

The parasitic infections are the major public health problems, presenting an endemic form in several areas of Brazil. They may present narrow relationship with social-demographical and environmental factors, such as: social-economical precarious conditions, consumption contaminated water, deficient nutritional condition of individuals and others, being frequently the infant population the most affected. In order to investigate the prevalence of intestinal parasites in indigenous and deprived populations and the key factors involved in the epidemiology of intestinal parasites, it was realized intestinal parasitological survey in residents of two Indian reservations: Bororó Reservation/MS and Xingu Reservation/MT (Kayabí and Juruna tribes); and also in residents of two cities: Pontes e Lacerda/MT and Ibateguara/Al. The data collection was conducted from 2002 to 2009. 2,754 faeces samples were analyzed by the methods of Faust, Hoffman, Kato-Katz, Rugai, Direct and modified Ziehl-Neelsen. The study obtained personal data and social-economical parameters. It was observed the presence of 73% of intestinal parasites in the Bororó Reservation, 62.77% in the Xingu Reservation, 52.61% in the cities of Pontes e Lacerda/MS and 67.42% in the Ibateguara city. The species of most prevalence in male individuals were Entamoeba coli (22.5%), Giardia duodenalis (11.6%), Entamoeba histolytica (13.9%) and Ascaris lumbricoides (13.6%). In female individuals were Entamoeba coli (24.1%), Giardia duodenalis (8.8%), Entamoeba histolytica/ E. díspar (13.8%) and Ascaris lumbricoides (13.3%). The prevalence of protozoan (42.6%) was higher than helminths (31.1%). For most analyzed groups there was no difference between the diarrhea clinical situation and the intestinal parasite type and number. The multiple intestinal parasite was detected in 12.8% of samples and monoparasitism in 46.5%. The minor age individuals presented the preponderance of protozoan infections.
