ABSTRACT

Enterohaemorrhagic Escherichia coli O157:H7 is an emerging pathogen, being actually an important cause of food-borne illness. Is responsible for serious outbreaks and sporadic cases of haemorrhagic colitis (HC) and haemolytic uraemic syndrome (HUS).
The major challenge of induced diarrhoeal disease is in children under the age of 10 and elderly people, especially the ones that live in lessdeveloped countries of the world, in which bacterial diarrhoeal diseases remain a significant public health problem. In incidence data, the reported rates in developed countries are 5-8 cases/100,000 population per year, with regional variations. Rarely reported in patients in less developed countries.
The epidemiology of the microorganism is revised in several countries being correlated serotypes of E. coli O157: H7 to the lethal indexes.
