Enteroparasitosis en alumnos de educación básica de la ciudad de Antofagasta (2006 - 2007) / Enteroparasitism in students of basic education in two municipal schools of the city of Antofagasta (2006-2007)

RESUMEN

In the northern part of Chile, due to its geoclimatic characteristics, enteroparasitosis in school children is mainly due to protozoos is such as Giardiosis and Blastocystosis, and Enterobiosis among helminthic infections. During the years 2006 and 2007, we made an enteroparasitosis survey of 92 school children in grades 1 to 8 in two municipal schools of Antofagasta. The global prevalence rate of parasites and commensals was 83.69%. We found frequencies of 68.48% for Blastocystis hominis, 8.70% for Giardia duodenalis, and 23.91% for Enterobius vermicularis. The frequencies for commensals were 18.48% for Entamoeba coli, 16.30% for Endolimax nana, 5.43% for Chilomastix mesnili and 3.26% for Lodamoeba bütschlii. We conclude that the frequency of infection by parasites and commensals among school children is related to the deficient sanitary conditions present in some sectors of the city of Antofagasta, associated with socioeconomic and cultural factors of the population.
