[Do enteroaggregative Escherichia coli is a significant clinical problem in Poland?].

Introduction: Enteroaggregative Escherichia coli are poorly discovered pathogenic subgroup of these microorganism. They can cause watery diarrhea witch is often persistent. It seems that infections due to EAEC could comprise significant epidemiologic problem, covered especially children from developing countries and travelers visiting these countries.

Methods: To find out, whether EAEC could comprise a problem in Poland, we examine 382 E. coli strains isolated from stool samples from patients with diarrhea in Poland in years 1997-2011. Three genes (aggR, aap and aat) were marked by Multiplex-PCR method.

Results: Six of examined strains (1.5%) were marked as EAEC and they were isolated equally from children and adults.

Conclusions: It seems that EAEC could not comprise a significant problem in Poland but it should be taken in to account as a potential etiologic factor of diarrhea.
