| مستخلص: | We evaluated a biochemical assay based on the ability to metabolise β‐phenylpropionic acid (PPA) as a diagnostic aid in the identification of typical enteropathogenic Escherichia coli(EPEC) strains. A total of 1061 E. colistrains of serogroups O55, O111, and O119 were initially characterised regarding their H types (serotypes) and the presence of EPEC DNA sequences, eae, EAF, and bfpA. In case of the serogroup O111 strains, 84.6% carried the typical EPEC markers, and the great majority of those (98.1%) were PPA‐positive. In contrast, only 0.9% of the serogroups O55 and O119 strains carrying the typical EPEC markers (53.6% and 75.4%, respectively) were PPA‐positive. We conclude that the PPA test is a useful method to detect typical EPEC strains only among strains of the O111 serogroup. |
