Abstract
The aim of this study was to collect data about the incidence of intestinal parasites in patients treated by the Public Health Service in the Municipal Hospital of Cumari, Goias. Parasitological tests were performed from January 2002 to December 2008, by Hoffmann, Pons and Janer’s method, or spontaneous sedimentation. From 1,029 samples, 373 (36.2%) presented parasites’ eggs or cysts, among them were species such as: Giardia lamblia, Entamoeba coli, Hymenolepis nana and Strongyloides stercoralis. Of these, Giardia lamblia presented the highest prevalence being constant over the six years of research. Its prevalence was high among different age ranges, with an average of 33.6% (n = 346). The high indexes of Giardiasis may be associated with the probable contamination of public drinking water systems, since this protozoan resists the action of chlorine added to treated water. This prevalence is similar to previously published studies; on those studies, the implementation of public health policies to control intestinal parasitosis was recommended.
