Abstract
A parasitological survey of children from five communitary day-care centers from Niteroi/ RJ – Brazil, was conducted in 1999. Of 218 children surveyed, 120 (55%) had positive samples for intestinal parasite. Among protozoa, Giardia lamblia was by far the most common species, detected in 38,3% of the cases, followed by Entamoeba coli (26,6%), Endolimax nana (17,5%), Entamoeba histolytica (11,6%) and Blastocystis hominis (2,5%). For the helminths, Ascaris lumbricoides (30%) was the most frequent, followed by Trichuris trichiura (26,6%), Hymenolepis nana (0,8%) and Enterobius vermicularis (0,8%). Monoparasitism was observed in 57,5% of the positive children. For the day-care center staff, Entamoeba coli was the specie with higher prevalence, probably due to ingestion of cysts in hands, food or water contaminated with human feaces. The high incidence of intestinal parasite, specially for protozoa, suggests the possibility of person-to-person transmition between children or the occurence of ingestion of contaminated food or water. These datas show the necessity of sanitary and educational programmes implementation for a better condition of children’s lifes from communitary areas of Niteroi/RJ.
