    Abstract
    Con el objeto de determinar el comportamiento de los Astrovirus como agentes causantes de diarrea en algunas regiones colombianas, se colectaron 1147 muestras de diarrea de niños menores de 5 años que acudieron a los servicios de consulta externa de cuatro centros de salud de regiones de Bogotá, Facatativa, Cartagena y Quibdo durante el periodo comprendido entre 1996 y el año 2002. La determinación de la presencia viral se realizó por medio de pruebas de ELISA encontrando una prevalencia global de 2,8%. De las muestras positivas se seleccionaron 14 a las cuales se les obtuvo su ARN, se realizaron pruebas de RT-PCR y secuenciación de un segmento de 348 pb del ORF 2 del genoma viral para elaborar dendrogramas con el método de Neiborg joining y así, determinar su comportamiento filogenético. Las conclusiones generales de este estudio fueron:que en Colombia los HAstV poseen comportamientos endémicos y que las cepas colombianas no han sufrido cambios evolutivos que les permitan distanciarse de cepas de otros países.
     
    In order to find the behavior of the Astrovirus isolates from diarrheic samples taken from children under 5 in four different cities of Colombian, there were tested 1147 samples between 1996 and 2002. The diagnosis of HastV was done by EIA and there were found 2,8% of global prevalence. Fourteen of the positive samples were typed by RT PCR and sequencing the 384bp region of the ORF2 segment of the viral genome (which codes for the capsid protein). Neighbor joining was done in order to make the phylogenetic study. The conclusions of the study were that in Colombia, HastV has an endemic behavior and the Colombian strains, obtained from samples of geographically distant or the same places, show that there is no genetic variability among the same genotype and among strains with the same typed but collected out of this country.
