FRECUENCIA DE ENTEROPARASITOSIS EN JARDINES INFANTILES ALEDAÑOS A LA CUENCA BAJA DEL RÍO TUNJUELITO

The purpose of this research was to determine the relationship between the frequency of entero-parasitism and the demographic and the socio-economic variables within pre-primary school nurseries located near the low basin of the Tunjuelito river (Bogota, D.C., Colombia), between august and september 2009. A study of the observational, descriptive and transverse type was realized. Demographic data and socio-economic factors were registered through the application of an instrument designed by the authors. Seriated samples of fecal material from 92 children, both males and females, were collected and processed by copro-parasitological methods. A frequency of 75% of intestinal parasites was determined; 57.6% were intestine commensals and 17.4% intestinal pathogens. As most frequent pathogens Giardia lamblia 7.6% and Entamoeba histolytica 7.6% were detected, followed by Ascaris lumbricoides (2.2%). The contact with the water of the river, the socio-economic level, the houses floor characteristics, the waste accumulation and the barefoot walking were the five variables, statistically significant in relation to the parasitic results. The existence of conditions suffered by the studied population constitutes a favorable context for the elevated existence of the parasitic intestinal diseases.
