Resumo: | Between March and October 1987, the prevalence of infection by Blastocystis hominis and other intestinal protozoan, their relationship with the age and sex of the hosts, and the percentage of in fected persons in family groups were determined in riverside communities of Valdivia River Basin, Chile. One or more intestinal protozoan species were determined in 72.5% of the examined persons. The prevalence was greater for B. hominis (61.8%). The prevalences of B. hominis, Endolimax nana and Entamoeba coli were greater in relation to the age of the host. The sex of the host and prevalence of infections by B. hominis and other species of intestinal protozoans did not show association. Prevalence of B. hominis was greater in persons from houses with no sanitary faeces disposal. Over 60% of the members of family groups showed infection by B. hominis in 53.1% of the groups compared to 2.4%-21.8% of infections by other protozoan species. Faecal samples of 45 pigs revealed 22.2% of infection by Blastocystis. |

Faecal samples of 45 pigs revealed 22.2% of infection by Blastocystis. Entre marzo y octubre de 1987 se examinaron muestras coprológicas de 970 personas (20, 9% de la población) pertenecientes a 209 grupos familiares de las comunidades ribereñas de la cuenca del rio Valdivia, Chile; con el propósito de determinar las prevalencias de infección por Blastocystis hominis y otros protozoos intestinales para establecer relaciones con la edad y sexo de los hospedadores, saneamiento ambiental y porcentaje de individuos infectados por grupo familiar. Un 72, 5% de las personas presentó una o más especies de protozoos intestinales. La mayor prevalencia se registró para B. hominis (61, 8%), que se incrementó con la edad del hospedador al igual que en las infecciones por Endolimax nana y Entamoeba coli. No se demostró asociación entre el sexo del hospedador y la prevalencia de infección por B. hominis y otras especies de protozoos. La prevalencia de B. hominis fue mayor en individuos que habitaban viviendas cuya disposition de excrementos era no sanitaria. Más del 60% de los integrantes de los grupos familiares presentaron infección por B. hominis en el 53, 1% de las familias encuestadas en contraposición al 2,4%-21,8% observado en infecciones por otros protozoos. El examen de 45 muestras de excrementos de cerdos, reveló infección por Blastocystis en el 22,2% de estos animales. Universidade de São Paulo.
