[Comparison of enteropathogenic Escherichia coli (EPEC) diagnosis by serology and by polymerase chain reaction (PCR)].

Introduction: The identification of EPEC in clinical laboratories is based on the determination of the serotypes by agglutination with O and H antiserum. Currently the proper diagnosis of EPEC should be done by the identification of the intimin gen (eaeA) by PCR.

Objectives: To compare the diagnosis of EPEC by serotyping and by PCR.
