Abstract: In order to compare the prevalence of intestinal microsporidiosis in children with severe mal- nutrition and eutrophic children at the Nutritional Recovery Unit, Chiquinquirá Hospital in Mara- caibo, State of Zulia, a chain reaction technique was performed on the polymerase (PCR) to iden- tify Encephalitozoon intestinalis and Enterocytozoon bieneusi in stool samples from 50 healthy and 50 severely malnourished children, whose ages were stratified as follows: younger infants (0-11 months), older infants (12-23 months), preschool (2-6 years) and school children (7-12 years). Of the microsporidia species investigated, Enterocytozoon bieneusi was evident in 14% of severely malnourished children and 8% of the eutrophic children. No amplifications for Encepha- litozoon intestinalis were obtained in the groups studied. On applying the chi-square statistical test, the result was not significant for the variables intestinal microsporidiosis and malnutrition. Conclusions are that the extent to which malnutrition and microsporidiosis relate is difficult to clarify, because malnutrition is a multifactorial condition, and it is not yet well established which of these two factors is the cause and which is the consequence. Resumen: Con la finalidad de comparar la prevalencia de Microsporidiosis intestinal en niños con des- nutrición severa y niños eutróficos de la Unidad de Recuperación Nutricional del Hospital Chi- quinquirá de Maracaibo, Estado Zulia, se realizó la técnica de reacción en cadena de la polimerasa (PCR) para la identificación de Encephalitozoon intestinalis y Enterocytozoon bieneusi en las muestras de heces de 50 niños desnutridos graves y 50 niños eutróficos, cuyas edades fueron estra- tificadas de la siguiente manera: lactantes menores (0-11 meses), lactantes mayores (12-23 meses), preescolares (2-6 años), y escolares (7 a 12 años). De las especies de microsporidios investigadas, se evidenció Enterocytozoon bieneusi en el 14% de los niños desnutridos graves y 8% en los niños eutróficos, no se ...
