  • PREVALENCE OF BLASTOCYSTIS SP IN CHILDREN AND ADOLESCENTS OF PERIURBAN COMMUNITIES OF CÓRDOBA CITY, ARGENTINA The objective of the present study was to learn the distribution of Blastocystis sp in children and adolescents of periurban communities of Cordoba city, Argentina. 204 individuals aged 0-21 from the communes Los Cedros and Villa del Prado were included. The socio-environmental characteristics were evaluated by means of a survey, and the parasitological analysis was performed by means of a macroscopic and microscopic examination. The characteristics of the communes were: rural work and brick manufacture as a source of income for their inhabitants, lack of drinking water and defi cit of environmental sanitation. 74% of individuals were infected with enteroparasites; 33% with one species and 41% with more than one species. Blastocystis sp was found in 39% of cases and with a higher prevalence among poliparasited children over 5 yr old. This microorganism was signifi cantly associated to infection with Giardia lamblia, Entamoeba coli and Enterobius vermicularis in poliparasited individuals. These fi ndings show a high prevalence of enteroparasites and Blastocystis sp as a main intestinal protozoan in preschool and school children in these periurban communes. These data could help to establish and consolidate epidemiological control and vigilance programmes as well as to intensify the educational work carried out with the members of these communes in order to avoid transmission, dissemination and persistence of parasitic infections.
