Frequency of enteroparasitic infections and serum positivity for Toxocara spp. in children from a public day care center in Southern Brazil

摘要: INTRODUCTION Day care centers play an important social role in children's early education and development. The objective of this study was to investigate the frequency intestinal parasitic infections infection with Toxocara spp. children from a day center city Rio Grande, Grande do Sul, Brazil. Methods: conducted using fecal samples 50 children, ages three six years, Ritchie, Faust, Rugai, Kinyoun's techniques. A closed structured epidemiological questionnaire used collect data parents/guardians children. Serological studies for detection antibodies by immunoenzymatic assays excretion secretion antigen (TES) were on sera collected 41 Results: enteroparasites 18%, 43.9% testing seropositive Low family income low literacy levels common factors between families parasite-positive For who tested positive spp., most reported only water sanitizing raw vegetables fruits. Conclusions: high seropositivity rates indicate that exposed parasite, it is reduce risk infection. In addition, interviews need educate studied population regarding modes parasite transmission prophylactic measures needed prevent their dissemination.
