Ocorrência de enteroparasitoses em escolares do município de Jataizinho, Estado do Paraná, Brasil / Occurrence of enteroparasitosis in schoolchildren of the municipal district of Jataizinho, State of Paraná, Brazil

As enteroparasitoses são responsáveis por altos índices de morbidade principalmente nos países em desenvolvimento, onde o crescimento populacional não é acompanhado de melhoria das condições de vida da população. O objetivo deste estudo foi determinar a ocorrência e os fatores associados às enteroparasitoses em escolares de Jataizinho, Estado do Paraná, Brasil. Foram avaliadas 264 amostras de fezes pelos métodos de sedimentação espontânea, método direto e Kato-Katz. A prevalência geral de enteroparasitoses foi de 68,2% (180/264). Os protozoários de maior prevalência foram a Endolimax nana (47,5%) e a Entamoeba coli (23,5%). Já entre os helmintos foram o Ascaris lumbricoides (10,2%) e o Trichuris trichiura (6,1%). Houve predominância de casos de poliparasitismo (50,5%) em relação aos de monoparasitismo (49,5%). Ovos de Schistosoma mansoni foram encontrados em quatro (1,5%) amostras analisadas. O principal fator associado às parasitoses intestinais foi o hábito de freqüentar rio, riacho ou lagoa (OR = 2,78; IC 95%; 1,32 ? 5,92). De acordo com os resultados encontrados, medidas de educação sanitária devem ser implantadas com urgência, enfatizando o risco de freqüentar rios ou lagos, melhores hábitos de higiene pessoal e higienização dos alimentos

The enteroparasitoses are responsible for high death rates, mainly in developing countries where population growth is not followed by improvement in the population?s standard of living. The aim of this study was to determine the occurrence of and the factors associated with enteroparasitosis in schoolchildren from Jataizinho, State of Paraná, Brazil. 264 fecal samples were analyzed by sedimentation in water, direct technique and Kato-Katz methods. The general prevalence of enteroparasitosis was of 68.2% (180/264). The most frequent protozoans were Endolimax nana (47.5%) and Entamoeba coli (23.1%). Already among the helminthes were Ascaris lumbricoides (10.2%) and Trichuris trichiura (6.1%). There was a predominance of poliparasitism cases (50.5%) in relation to the monoparasitism (49.5%). Schistosoma mansoni eggs were found in four (1.5%) of the analyzed samples. The main factor associated with intestinal parasitosis was related to the habit of bathing in rivers, streams or lakes (OR = 2.78; IC 95%; 1.32 ? 5.92). According to the results obtained, sanitary education measures should be urgently implemented, emphasizing the risk of the habit of bathing in rivers and lakes, better personal hygiene habits and hygiene procedures for food

Toxoplasma antibody and stool parasites in public school children, Rolandia, Parana, Brazil

The occurrence of toxoplasmosis and enteroparasitosis was studied in 434 children from elementary schools in the rural and urban areas of RolÔndia, Paranß State, Brazil. Sera and fecal samples from all the students were submitted to IFA for Toxoplasma gondii and coproparasitological tests, respectively. The children were tested by Amsler grid and 72 of them were examined for the presence of lesions compatible with ocular toxoplasmosis. Some variables were tested but none showed increased risk for toxoplasmosis. The distribution according to sex and age and also same other variables are presented and discussed. Correlations between Amsler's grid test, toxoplama RIFI, occurrence of eyes lesions and enteroparasitosis are also considered.
