Enteroaggregative Escherichia coli (EAEC) isolates obtained from non-diarrheic children carry virulence factor-encoding genes from Extraintestinal Pathogenic E. Coli (ExPEC).

Enteroaggregative E. coli (EAEC) is one of the most frequent pathogens isolated from diarrheal patients as well as from healthy individuals in Brazil and has recently also been implicated as an extraintestinal pathogenic E. coli (ExPEC) associated with bloodstream and urinary tract infections.
