“…The medicines used in the villages, including, in particular, the products used against intestinal parasites, were exclusively those prescribed and distributed free of charge by the nurse and the health care agents of the clinic at Zidock. Three recent studies on the Indians of Brazilian Amazonia (Ferrari et al, 1992;Miranda et al, 1999) and central Brazil (Santos et al, 1995) reported frequencies of parasitism lower than those reported here, except for…”

Summary :Intestinal parasitism and its epidemiological characteristics were studied in an isolated Amerindian population from Upper Oyapock (French Guiana) that has retained its traditional social and cultural specificities. This population consisted of 138 Wayampi Indians, 68 adults and 70 children (below the age of 15 years), with a sex ratio (M/F) of 0.86, spread over the four villages of the community of Trois Sauts, corresponding to more than two thirds of the population recorded as inhabiting the sector in the last census (375 inhabitants). Fecal examination combined the direct examination of fresh feces with the quantitative techniques of Kato-Katz method, Baermann and MIF staining. Overall, 92 % of the subjects were found to have intestinal parasites, 85 % if only direct examination of fresh stools was taken into account. Fourteen species of human parasite were identified: seven protozoa and seven helminths. We observed in particular 1) a high frequency of hookworm infection due to Necator americanus. Over 50 % of subjects were affected, with a range of 25 % to 75 % according to the village, but with only moderate parasite loads; 2| a high level of parasitism by E. histolytica/E. dispar (17 %), Stongyloides stercoralis (16 %) and Hymenolepis nana (18%) ; 3) a lower level of parasitism by Ascaris lumbricoides and very low levels (almost absent) of Trichiuris trichiura ; 4) the absence of Schistosoma and fluke eggs. With the exception of H. nana, which was more frequent in children than in adults, there was no significant difference in the level of parasitism according to sex and age. Although the Wayampi of French Guiana are French citizens and consequently have quite high incomes and ready access to clinics and medicines, intestinal parasites are far from under control in this population. A lack of fecal hygiene and the habit of walking barefoot are widespread in the unchanging Amazonian environment and contribute to this phenomenon.KEY WORDS : intestinal parasites, epidemiology, Amerindians, French Guiana.

“…The rate of infestation in the present study is similar to the reported in other studies in indigenous communities in Brazil, for instance in Suruí Indians (29.5%) and in the ethnic group Karitiana (10.8%) from State of Rondônia, in Maxakali Indians, from State of Minas Gerais (18.16%), in members of the ethnic group Kaigàng from State of Pará (31.7%) and in children from the Xingu Indian Reservation (28.5%) [10,11,12,13,14]. Our results are also in agreement with studies performed in other parts of the world [15,16].…”

A total of 1528 stool samples were examined during a survey of intestinal parasites in 542 members of the Tapirapé ethnic group (279 females and 263 males), who live in the Brazilian Amazon region of Mato Grosso. Overall, 542 individuals from six indigenous villages were enrolled of whom 45 (8.3%) were positive for Hymenolepis nana based on analysis by microscopy of fecal concentrates. H. nana was more prevalent in male individuals (77.8%) as compared to females (22.2%). Moreover, males aged under 15 years have been associated with positivity for H. nana (P = 0.02). This study is the first report of the prevalence of H. nana in members of the indigenous Tapirapé ethnic group from the Brazilian Amazon.

“…Recent use of anti-helminthic drugs, reported by nearly-one third of our study subjects, could account at least partially for the low prevalence of helminth infections in this and other rural Amazonian settings 19 . Intestinal parasitism seems to remain highly prevalent, in contrast, in more remote Amazonian communities, with little access to health care and medications 6,8 .…”

Prevalence and spatial distribution of intestinal parasitic infections in a rural Amazonian settlement, Acre State, Brazil

IntroductionIntestinal parasites are estimated to infect more than three billion people worldwide 1 . Most intestinal parasites are heterogeneously distributed in host populations; according to a frequently quoted estimate, 10% of hosts harbor 70% of the intestinal helminths 2 . Specific groups at increased risk of intestinal parasitic infections represent ideal targets of public health interventions. Chemotherapy-based programs to control intestinal nematodes, for example, usually target schoolchildren, who are often at increased risk of both infection and significant morbidity 3 .Despite the widely recognized role of environmental determinants of intestinal parasitism, the impact of interventions such as improved water supply and increased availability of latrine facilities has attracted relatively little attention 4 . The design and evaluation of large-scale sanitation interventions require appropriate spatial analysis of epidemiological data, since their targets are high-risk geographic units instead of high-risk individuals. Therefore, the study of the spatial distribution of intestinal parasitic infections can facilitate identification of modifiable factors that could be addressed by suitable interventions, or at least guide public health policies to appropriate interventions. Such an example is provided by a recent study of risk factors and spatial patterns of hookworm infection in a rural area in Côte d'Ivoire, where spatial analysis was ARTIGO ARTICLE
