Parasitoses intestinais na comunidade de Martinésia, zona rural de Uberlândia, Minas Gerais / Intestinal parasitosis in the community of Martinésia, rural zone of the municipality of Uberlândia, state of Minas Gerais

Este estudo foi realizado para determinar as taxas de prevalência de parasitos intestinais e avaliar possíveis comportamentos de risco, em nível domiciliar, na comunidade do distrito rural de Martinésia (Uberlândia, MG). Amostras fecais individuais de 162 moradores foram examinadas, segundo os métodos Ruggai e Lutz, entre julho e outubro de 1998. O coeficiente geral de prevalência das enteroparasitoses foi de 21,6% (13,6% de helmintíases e 9,3% de protozooses). Homens foram mais acometidos do que mulheres (30,3% e 15,6%, respectivamente). Dos 35 indivíduos positivos, 22 portavam helmintos, que foram mais freqüentes entre jovens e adultos jovens (11 a 30 anos). Protozooses foram mais prevalentes em crianças (até 10 anos). Os principais parasitos encontrados foram: Giardia lamblia (9,3%), ancilostomatídeos (5,6%) e Enterobius vermicularis (4,3%). Não lavar as mãos antes das refeições ou após usar o banheiro, consumir alimentos não lavados, ingerir água não tratada e baixa renda familiar foram variáveis associadas à ocorrência de parasitos intestinais.

This study was carried out to determine the prevalence rates of intestinal parasites and to evaluate possible risk behaviors, at domiciliary level, in the community of the rural district of Martinésia, municipality of Uberlândia, State of Minas Gerais. Individual fecal samples of 162 dwellers were examined, by Rugai and Lutz methods, from July to October 1998. The overall prevalence rate was 21,6% (13.6% to Helminthiasis and 9.3% to Protozoosis). Men were more attacked than women (30.3% and 15.6% respectively). From 35 positive individuals, 22 hosted helminthes, which were more frequent in youths and young adults (from 11 to 30 years old). Protozoosis were more prevalent in children (under 10 years). The main parasite founded were: Giárdia lamblia (.3%), hookworms (5.6%) and Enterobius vermicularis (4,3%). No wash hands before meals and/or after to use baths, to consume food no washed, to drink water not treated and low familiar rent were variables associated to the occurrence of intestinal parasites.

Ocorrência de parasitas e comensais intestinais em crianças de escola localizada em assentamento de sem-terras em Campo Florido, Minas Gerais, Brasil / Occurrence of intestinal parasites and commensal organisms among schoolchildren living in a 'landless farm workers' settlement in Campo Florido, Minas Gerais, State Brazil

O objetivo deste estudo foi verificar a ocorrência de parasitas e comensais intestinais em crianças de escola localizada em assentamento de sem-terras em Campo Florido, Minas Gerais, Brasil. Exames coproparasitológicos realizados em 72 indivíduos evidenciaram 59,7 por cento de positividade, sendo identificados 4 tipos de protozoários e 5 de helmintos. Concluiu-se que há necessidade de acompanhamento das condições de saúde desta populaçäo

Parasitological and immunological diagnoses of strongyloidiasis in immunocompromised and non-immunocompromised children at Uberlândia, state of Minas Gerais, Brazil

Parasitological and immunological diagnoses were part of a study conducted among 151 children, 83 immunocompromised (IC) and 68 non-immunocompromised (non-IC) aged from zero to 12, seen at the University Hospital, Universidade Federal de Uberlândia, State of Minas Gerais, Brazil, from February, 1996, to June, 1998. Three fecal samples from each child were analyzed for the parasitological diagnosis by Baermann-Moraes and Lutz methods. The immunological diagnosis to detect IgG and IgM antibodies was carried out by the indirect immunofluorescence antibody test (IFAT) with cryo-microtome sections of Strongyloides stercoralis and Strongyloides ratti larvae as antigens and by the ELISA test with an alkaline extract of S. ratti as the antigens. Of the 151 children 5 (3.31 percent) were infected with larvae of S. stercoralis (2 cases IC, 2.41 percent, and 3 cases non-IC, 4.41 percent). The IFAT-IgG detected 7 (8.43 percent) serum samples positive among IC, and 2 (2.94 percent) cases among non-IC. The ELISA-IgG test detected 10 (12.05 percent) serum samples positive among IC, and 1 (1.47 percent) case among non-IC. The IFAT-IgM detected 6 (7.22 percent) positive cases among IC, and 3 (4.41 percent) cases among non-IC. ELISA-IgM test detected 10 (12.05 percent) positive cases among IC, and 3 (4.41 percent) cases among non-IC. It was concluded that the immunological tests can help in the diagnosis of strongyloidiasis in immunocompromised children
