%X Blastocystis hominis es un organismo emergente cuya prevalencia se ha incrementado en los 迆ltimos a os. La frecuencia en M谷xico va de 4,0% a 62%, sin reportes previos en el estado de Guerrero. La poblaci車n estudiada fueron tres localidades del estado de Guerrero: Chilpancingo, Petaquilla y Tixtla en un total de 1.138 ni os preescolares y escolares, de ambos sexos. Mediante tres t谷cnicas coproparasit車scopicas (CPS): examen directo, concentraci車n por flotaci車n de Faust y cultivo de Barret, se detectaron un total de 38% de ni os parasitados y B. hominis ocup車 el primer lugar con el 61% de los CPS positivos. El 90% de los casos fueron parasitosis 迆nica. El 58% de los ni os aparentemente sanos y con B. hominis declararon tener alg迆n s赤ntoma gastrointestinal. La asociaci車n de B. hominis con dolor abdominal y beber agua de la llave tuvo diferencia significativa. Proponemos una transici車n parasitaria a B. hominis como principal par芍sito del hombre, como resultado de las medidas de control para las parasitosis intestinales. Blastocystis hominis is an enteric emergen organism found in human it's prevalence has been increasing in the lasts years. The frequency in Mexico is from 4.0% to 62%, without reports in the Guerrero state. The aim of this study was to inform the parasitic transition to B. hominis in the Central Zone of Guerrero state. The population in this study were three communities of Guerrero state: Chilpancingo, Petaquilla and Tixtla in a total of 1,138 preschools and schools children of both sexs. Three parasitological tests were used for detection of the parasite in stool specimens: micrscopy of direct smears, concentration and flotation technique and serum-solution saline culture. Global prevalence of parasites was of 38% and B. hominis was the principal parasite with 61% on the positive tests. The 90% were only B. hominis and 10% with others parasites. A total of 58% of the children healthy with B. hominis declarated have gastrointestinal symptoms. The association ofB. hominis with abdominal pain and drinking taste water had significant difference. We propuse a parasitic transition to B. hominis as principal human parasite, this can be the result of man-made intervention in the intestinal parasitosis control.
