[Enterohaemorrhagic Escherichia coli O157:H7 infection].
Escherichia coli O157:H7 differs from previously described diarrheagenic E. coli classes (enteropathogenic, enteroinvasive, enterotoxigenic) by distinct clinical symptoms, production of verotoxin (VT) and a specific plasmid. Cattle are the primary reservoirs of E. coli O157:H7. The organism may be transmitted through the consumption of contaminated foods (mainly of bovine origin) and by person-to-person contact. The most typical clinical manifestations of E. coli O157:H7 infection are hemorrhagic colitis and hemolytic-uremic syndrome. Since the 1982 many outbreaks of E. coli O157:H7 infections as well as sporadic cases have been documented. Diagnosis of E. coli O157:H7 is based on a positive stool culture, presence of VT and elevated serum antibodies. The best currently available and inexpensive method for diagnosing E. coli O157:H7 is culture of stool on sorbitol-Mac Conkey agar medium.
