Background: Human cysticercosis (CC) is a global public health problem, especially in Latin America, including Brazil. We aimed to analyze the seroprevalence of CC among school-age children and adolescents. Methods: We analyzed the presence of specific IgG antibodies against Taenia solium metacestodes in 500 serum samples from elementary school children and adolescents in Jataí City, state of Goiás, Brazil. IgG antibodies against the antigenic extract of the parasite were detected and analyzed by ELISA, and specific peptides were identified by confirmatory Western Blotting test. Results: Of the 500 study participants, 205 (41%) were male, and 295 (59%) were female. Participants aged between 4 and 18 years (mean age 8.4 years). The percentage of serum samples reactive by ELISA was 37.2%. These samples were analyzed by Western Blotting, which confirmed that the seropositivity rate was 6.2% (95% CI 2.4–14.7) in 31 samples reactive for CC-specific bands, determined in serum samples from 18 male (5–11 years old) and 13 female (4–12 years old) students. Conclusion: The CC seroprevalence demonstrated in schoolchildren suggests that this parasitosis is endemic in the study area. Further investigations are necessary to clarify the local epidemiology of this parasitosis.
O presente relato de experiência trata de um projeto de extensão do Curso de Biomedicina, da Universidade Federal de Jataí, que foi desenvolvido no município de Jataí-GO, com o objetivo de promover a educação em saúde de escolares sobre o tema enteroparasitoses, importante problema de saúde pública no Brasil. Foram distribuídos panfletos informativos sobre o tema, além de palestras, oficinas, teatros e brincadeiras. O total de 698 estudantes, matriculados desde a pré-escola até o 9º ano do ensino fundamental, participou do projeto. As ações foram desenvolvidas em quatro escolas públicas municipais, no período de janeiro de 2011 a dezembro de 2013. Os saberes dos escolares sobre parasitoses intestinais foram estimados numa amostra de 200 estudantes alfabetizados; em dois momentos, inicialmente, com 100 estudantes antes da realização das ações de educação em saúde (grupo denominado não instruído) e com outros 100 estudantes após as atividades (grupo instruído). As atividades de extensão desse projeto permitiram interações entre graduandos em Biomedicina e estudantes do ensino infantil e fundamental, contribuindo na formação de cidadãos com responsabilidade social baseada na reflexão sobre as medidas de profilaxia aplicadas às parasitoses intestinais.
