By the performance of parasitological examination of one fecal sample per individual, a total of 256 persons from a rural county in the X Region (41 degrees 50 minutes South lat., 73 degrees 05 minutes West long.) were studied. The general rates of infection by intestinal parasite and/or commensal protozoa and helminths found were: Giardia intestinalis 14.1%, Entamoeba histolytica 11.7%, Blastocystis hominis 36.0%, Entamoeba coli 9.8%, Endolimax nana 16.4%, Iodamoeba buetschlii 1.2%, Chilomastix mesnili 0.8%, Ascaris lumbricoides 13.7% and Trichuris trichiura 9.8%. The prevalence rates of intestinal infection led us to conclude that environmental conditions favorable for its transmission remain and show that intestinal parasitoses are still a public health problem in this region, affecting mostly children.
