Outbreaks generated by VTEC In contrast to infections with EPEC, ETEC and EIEC, human disease caused by VTEC belonging to serogroup O157 (VTEC O157) has been recognized as an emerging problem in the UK. VTEC O157 and strains belonging to other serogroups are associated with a spectrum of disease, including mild diarrhoea, loathly bloody diarrhoea and haemolytic uraemic syndrome, which is the close to common cause of acute renal failure in children in the UK. The massive majority of data on VTEC in the UK relate to serogroup O157 because of the eclipse of simple tests and laboratory surveillance for VTEC of other serogroups. Outbreaks of infection caused by non-O157 VTEC study not been reported so far in the UK, save several have been investigated in the Republic of Ireland and Continental Europe. Outbreaks of VTEC O157 infection in the UK have been reported since 1985.
