REQUENA, Ixora et al. Enterobius vermicularis in preschool children from a suburban area in San Félix, Bolívar State, Venezuela. Invest. clín [online]. 2007, vol.48, n.3, pp.277-286. ISSN 0535-5133.

To determine the enterobiosis prevalence in preschool children, a study was carried out from may-july 2003, in the SEU “Teresa de la Parra” in San Félix, Bolívar State, Venezuela. Three samples from the perianal region were obtained from every child, by applying the Graham method, and one sample was obtained of the subungueal deposit by scraping and cutting off their finger nails. These samples were preserved in 10% formol and processed by the formol-ether method. Also, a stool sample was collected and analyzed by direct examination and the formol-ether method. The prevalence of Enterobius vermicularis was 45.8% (27/59). No differences in relation to age (Χ ² = 1.23 d. f. = 2) and sex (p > 0.05) were observed between the infected children. The eggs E. vermicularis were not observed in the 59 samples of subungueal deposits. In conclusion, although the enterobiosis prevalence was high, as determined by the Graham method, a relationship could not be found between E. vermicularis in the scotch tape and the finger nail samples of the children evaluated.
