Diarrheagenic Escherichia coli markers and phenotypes among fecal E. coli isolates collected from Nicaraguan infants

J Clin Microbiol. 2010 Sep;48(9):3395-6. doi: 10.1128/JCM.00228-10. Epub 2010 Jul 14.


We analyzed the prevalence of diarrheagenic Escherichia coli (DEC) markers and common phenotypes in 2,164 E. coli isolates from 282 DEC-positive samples. Enteropathogenic E. coli (EPEC) and enteroaggregative E. coli (EAEC) were very diverse and were not correlated with diarrhea. Enterotoxigenic E. coli (ETEC) estA and enterohemorrhagic E. coli (EHEC) belonged to a few phenotypes and were significantly correlated with diarrhea.
