The frequency of diarrhoeagenic Escherichia coli (DEC) strains was investigated in 253
children up to 3 years old, with (patient group, PG, 199 children) and without (control group�…

In a prospective study carried out in two urban centers in northeastern Brazil, 195 HEp-2-

Background Childhood diarrheal diseases remain highly endemic in developing areas of
Brazil. The importance of Escherichia coli among children with diarrhea in these areas was�…

The aim of the present study was to investigate the prevalence of D iarrheagenic E
scherichia coli (DEC) pathotypes, a leading cause of diarrhea worldwide, among diarrheal�…

In the present study, 470 children less than 72 months of age and presenting acute diarrhea
were examined to identify associated enteropathogenic agents. Viruses were the pathogens�…

OBJECTIVE: Since diarrheagenic E. coli are not identified by common clinical laboratory
techniques, we hypothesized that these organisms might be an unrecognized cause of�…
