An examination for prevalence of intestinal parasitic infection in Khlong Toei district community in Bangkok was carried out from October 2003 to February 2004. Four hundred and twenty stool specimens were obtained and examined by using the simple smear and Kato-Katz thick smear techniques. The results showed that the prevalence of intestinal parasitic infection was 9.05%. Hookworms comprised 2.38% of the parasites, Strongyloides stercoralis 1.90%, Ascaris lumbricoides 1.67%, Taenia spp. 1.19%, Entamoeba coli 0.95%, Endolimax nana 0.48%, Opisthorchris viverini 0.48% and Trichuris trichiura 0.24%.
Results from this study revealed that sex, age, personal background, socioeconomic status, housing sanitation and personal hygiene did not contribute to varying rates of infection ( p  >  0.05 ). On the basis of these results, we conclude that intestinal parasitic infection is an important public health problem in Khlong Toei district community and intestinal parasitic control programs need to be instituted.
