dc.description.abstractThe aim of the study was to determine the frequency of six genes encoding serine protease autotransporter proteins Enterobacteriaceae (SPATE) in diffusely adherent Escherichia coli (DAEC) isolates from children with (WD, n=63) and without diarrhea (WOD, n=41) from Lima, Peru. WOD were considered a control group. For the detection of the genes, 2 multiple PCRs were standardized: triple A (sigA, pet, espP) and triple B (sat, pic, espC). In both groups, the most frequent SPATE gene was Sat (39.7% of WD and 41.5% of WOD), followed by spP (20.6% and 9.7% in WD and WOD respectively). The other genes were detected in proportions lower than 10.0%, in the following order of frequency: pet, sigA, espC and pic, without significant differences between the groups. It was concluded that Sat is the most frequent SPATE in DAEC and that these strains may possess SPATE genes regardless of whether they are isolated in WD or WOD.en_US
dc.description.abstractEl objetivo del estudio fue determinar la frecuencia de seis genes que codifican proteínas autotransportadoras serin-proteasa de Enterobacteriaceae (SPATE) en aislamientos de Escherichia coli difusamente adherente (DAEC) provenientes de niños con diarrea (NCD, n=63) y sin diarrea (NSD, n=41) de Lima, Perú. Los NSD se consideraron como grupo control. Para la detección de los genes se estandarizaron 2 PCRs múltiples: triple A (sigA, pet, espP) y triple B (sat, pic, espC). En ambos grupos el gen SPATE más frecuente fue sat (39,7% de NCD y 41,5% de NSD), seguido de espP (20,6% y 9,7% en NCD y NSD respectivamente). Los otros genes se detectaron en proporciones inferiores al 10,0%, en el siguiente orden de frecuencia: pet, sigA, espC y pic, sin diferencias significativas entre los grupos. Se concluye que Sat es la SPATE más frecuente en cepas DAEC, y que estas cepas pueden poseer genes SPATE independientemente de si se aíslan en NCD o NSD.es_PE
