[Hemolytic-uremic syndrome--microbiological study].

In autumn 1988 in one locality of the North Bohemia region young children developed severe diarrhoea and the children were sent because of their serious clinical condition with the diagnosis of haemolytic-uraemic syndrome (HUS) to the Prague-Motol hospital. The probable aetiological agent which was detected was Escherichia coli producing verotoxin (VTEC)--026:H11, 026:H?, O157:H7, 05:H- and 01:H?. Biotyping and serotyping of the strains was made, the verotoxin level was assessed and their sensitivity to antibiotics was tested. Concurrently contacts were examined and suspect colonies of Escherichia coli were subjected to bio- and serotyping, however, none of the serovars found in the sick children was detected.
