Description
Summary:Toxoplasmosis is one of the most common zoonoses worldwide. The seroprevalence for T. gondii in human population from Brazil might range from 40 to 80%. The aim of this paper was to study the seroprevalence of T. gondii infection in children from age one to 15 living in a low socioeconomic community, named community of Jardim São Remo in the year of 2002. The community is located in the West area of São Paulo municipality, São Paulo State, Brazil. Antibodies to T. gondii were found in 110 (32.4%, CI 95%: 27.5 - 37.7) of the 339 children tested with indirect immunofluorescent antibody test. The titration of the samples revealed 29 children with serum titer equal to 16, 14 children with 32, 18 children with 64, 21 children with 128, 20 children with 256 and eight children with serum titer > 512. The age dependence of the prevalence of T. gondii infection and the association between seroprevalence for T. gondii and seroprevalence for T. canis suggest that the infection is chiefly postnatal. Seroconversion in infant population of community Jardim São Remo occurs in children as young as two years old, earlier than in the children attended at health centers of São Paulo city. The seroprevalence of T. gondii in children from Jardim São Remo was compared to the prevalence in children from other urban centers of Brazil. A toxoplasmose é uma das zoonoses mais comuns em todo o mundo. Estima-se que a soroprevalência desta enfermidade na população humana do Brasil esteja entre 40 e 80%. O objetivo deste estudo foi estimar a soroprevalência para a infecçção pelo T. gondii em crianças entre um e 15 anos de idade em uma comunidade de baixa renda denominada comunidade Jardim São Remo, durante o ano de 2002. A comunidade estudada localiza-se na região Oeste do município de São Paulo, no estado de São Paulo, Brasil. Anticorpos contra T. gondii foram encontrados em 110 (32,4% IC 95%: 27.5 - 37.7) das 339 crianças submetidas ao teste de imunofluorescência indireta. A titulação das amostras revelou 29 amostras com título igual a ...
