Parasitoses intestinais de indígenas da comunidade Mapuera (Oriximiná, Estado do Pará, Brasil): elevada prevalência de Blastocystis hominis e encontro de Cryptosporidium sp e Cyclospora cayetanensis

Abstract

As fezes foram trazidas por pesquisadora que esteve na aldeia para realizar determinada investigação científica.Para conhecer particularidades concernentes a indígenas, no Brasil, várias apreciações já foram ou ainda são realizadas. Diversas publicações atestam isso e, como exemplos, abordaram diabetes, alcoolismo, estado nutricional, segurança alimentar, questão sociolingüística, epidemiologia, câncer e nutrição no âmbito da saúde infantil 8 9 . Parasitoses intestinais ficaram reiteradamente focalizadas e demonstraram percalços expressivos ABSTRACTOccurrences of intestinal parasitosis in Indians of the Mapuera community (Oriximiná, State of Pará, Brazil) were evaluated. Within the context of group assessment, this study makes a contribution towards adequate knowledge of this subject, which is significant from a medical-sanitary point of view. Parasitological examination of feces from 83 individuals, performed using four different methods, could be considered to have reasonable amplitude for establishing diagnoses. Protozoan cysts and helminth eggs of many types were found, even with significant percentages. The frequent presence of Blastocystis hominis (57.8%), along with findings of Cryptosporidium sp (3.6%) and Cyclospora cayetanensis (10.8%), deserved highlighting with specific comments. The findings show that these Indians live in an environment in which poor hygiene conditions prevail. In particular, these facilitate the dissemination of protozoa and helminths through contact with the soil or through intake of contaminated water and food.

Intestinal parasites in two indigenous ethnic groups in northwestern Amazonia

“…Though two parasitological techniques were used to detect intestinal protozoans and helminths, parasites commonly found in some indigenous populations were not detected, such as Cryptosporidium, Cyclospora cayetanensis (Borges et al 2009), and Strongyloides stercoralis (Santos et al 1995). Further analysis, including other methods of detection and staining of intestinal parasites (Clarke and Mclntyre 1996;Machado et al 1998), may reveal the prevalence of these species in Baniwa and Bare communities and may strengthen our evidence of a high frequency of intestinal parasites among these indigenous populations.…”

Additionally, the inclusion of other parasitological techniques could reveal occurrence of B. hominis, since other studies reported a high prevalence of B. hominis in indigenous communities in the Brazilian states of Pará (Borges et al 2009) and Mato Grosso do Sul (Aguiar et al 2007). …”

Molecular Characterization of Blastocystis Obtained from Members of the Indigenous Tapirapé Ethnic Group from the Brazilian Amazon Region, Brazil

“…15,16 The background prevalence of Blastocystis in Brazilian indigenous populations has been determined by direct examination of fecal samples on only two previous occasions, 17,18 and nothing is known about the subtype distribution of Blastocystis in these cohorts. The only published study on Blastocystis subtypes in Latin America, a region inhabited by > 500 million people, was performed on only 12 isolates from Colombia.…”

Potential for shistosomiasis in a municipality of Rondônia, Brazilian Amazon

“…Intestinal parasites are highly prevalent in the Brazilian Amazon Souza et al 2007;Borges et al 2009) and have also been reported in other regions of Brazil, such as the cities of Parnaíba, Piauí (Furtado and Melo 2011;Oliveira et al 2001), and São José da Bela Vista, as well as São Paulo, where the infection rate was 44.4% (Tavares-Dias and Grandini 1999), all these locations had inadequate sanitation.…”
