Intimin subtyping of atypical enteropathogenic Escherichia coli isolated from children with and without diarrhea: a possible temporal shift in the distribution of intimin alleles.

Intimins of atypical EPEC strains from children with and without diarrhea were genotyped. κ was not found and ß was the most common. η- and ζ-alleles prevailed in strains from children without diarrhea and ι-allele among children older than 13 months. ε-allele emerged in 2006 and was the most common in 2007.
