ARIAS B, Isabel et al. Escherichia coli enteroagregativa en niños con diarrea de un hospital de Lima. Rev. perú. med. exp. salud publica [online]. 2004, vol.21, n.3, pp.176-178. ISSN 1726-4634.

Amongst Escherichia coli causing diarrheal disease, enteroaggregative E. coli is one of the most important organisms, and it is frequently associated to diarrhea in infants. The study was performed aiming at detecting virulence factors for the aforementioned organism, using colony blood hybridization with specific deoxyribonucleic acid (DNA) probes. 233 samples isolated in the Pediatric Emergency Hospital Laboratory between december 1998 and april 1999. Of all samples analyzed, it was found that 17,16% of them have the typical virulence factor for their category. The resultsprove that an important proportion of isolates in children with diarrheal disease have enteroaggregative E. coli.
