Using multiplex PCR, we detected Escherichia coli strains harbouring genes for virulence factors typical for Shiga-like toxin-producing Escherichia coli strains. In our study we included two groups of patients: the first with uncomplicated diarrhoea and the second with clinical signs of haemolytic uremic syndrome. The aim of study was to find STEC among children with diarrhoea and haemolytic uremic syndrome, and to confirm the presence of STEC in those suffering from HUS using multiplex PCR. We have found STEC among children with gastroenteritis but we did not detect any STEC in children with HUS.


Key words: STEC, multiplex PCR, shiga-like toxins, HUS.
