Intestinal Parasitism in San Cayetano, Corrientes, Argentina1
نویسنده
چکیده
An epidemiologic study was conducted in San Cayetano, a village in the province of Corrientes, Argentina, fo determine the prevalence of intestinal parasitoses in children. Eighty-eight households were randomly selected. Stool samples were collected from 207 children (72% of the school-age populafion and 12% of fhe total village population) over a period of six consecutive days, and were subjected to microscopic examination. Of the samples examined, 170 (83%) contained one or more parasites, of which the most frequently found was Blastocystis hominis (in 43% of the samples). Other parasites and commensals detected included Giardia larnblia (29%), hookworms (27%), Entamoeba coli (270/o), Enterobius vermicularis (4%), Strongyloides stercoralis (20/o), and Ascaris lumbricoides, Trichuris trichiura, Taenia saginata, Isospora belli, Iodamoeba bi&&lii, and Balantidium coli (each 0.5%). The high observed prevalence of intestinal parasitoses indicates active parasite fransmission in San Cayetano as a result of poor environmental hygiene-ascribable largely to a lack of public water supply, sewerage, and waste removal services.
